108-555: The Old Hume Highway , an urban and rural road , may be described as any part of an earlier route of the Hume Highway , which traverses Victoria and New South Wales between the cities of Sydney and Melbourne in Australia . In some places, the highway has been deviated several times since the first rough track was made between Sydney and Melbourne in November 1842. Since the time of

216-400: A road use tax , is payable on some vehicles used on the public road. The definition of a road depends on the definition of a highway; there is no formal definition for a highway in the relevant Act. A 1984 ruling said "the land over which a public right of way exists is known as a highway; and although most highways have been made up into roads, and most easements of way exist over footpaths,

324-411: A single carriageway road is converted into dual carriageway by building a second separate carriageway alongside the first, it is usually referred to as duplication , twinning or doubling . The original carriageway is changed from two-way to become one-way, while the new carriageway is one-way in the opposite direction. In the same way as converting railway lines from single track to double track ,

432-457: A 25 to 50 millimeter hole through the pavement into the sub-base with a dry-bit roto-hammer . Next, a two-part epoxy is poured into the hole – dyed for visual clarity. Once the epoxy hardens, technicians drill through the hole. If a void is present, the epoxy will stick to the core and provide physical evidence. Common stabilization materials include pozzolan -cement grout and polyurethane. The requirements for slab stabilization are strength and

540-605: A May 2009 report by the American Association of State Highway and Transportation Officials (AASHTO) and TRIP – a national transportation research organization – driving on rough roads costs the average American motorist approximately $ 400 a year in extra vehicle operating costs. Drivers living in urban areas with populations more than 250,000 are paying upwards of $ 750 more annually because of accelerated vehicle deterioration, increased maintenance, additional fuel consumption , and tire wear caused by poor road conditions. When

648-506: A capacity of 20 people. There was also a cabin. The minister onboard, Rev. William Bussell, doubled as captain. On 16 August 1898, Etona arrived at Renmark , where the Bishop of Adelaide , Rev. Dr. John Harmer , held services the following Sunday with the assistance of Rev H M Wylie. In September of the same year, the service due in Holder on the 18th was suspended due to the vessel grounding on

756-419: A double-wheeled, steel roller to insert the rod to the desired depth. After inserting the backer rod, the sealant is placed into the joint. There are various materials to choose for this method including hot pour bituminous liquid, silicone and preformed compression seals. Careful design and construction of roads can increase road traffic safety and reduce the harm (deaths, injuries, and property damage) on

864-518: A list of birds and mammals . George "Chinese" Morrison , then aged 18, navigated the river by canoe from Wodonga to its mouth, in 65 days, completing the 1,555-mile (2,503 km) journey in January 1881. Shipping cannot enter the Murray from the sea because it does not have an estuary . However, in the 19th century the river supported a substantial commercial trade using shallow-draft paddle steamers ,

972-641: A major deviation of the highway was constructed in the 1930s due to the inundation of the original route caused by the raising of the wall of the Hume Dam on the Murray River . The deviation commences at Bowna and terminates at Guinea Street, Albury (the first part of the Riverina Highway east from Albury as far as what is now Old Sydney Road was until then the Hume Highway). On the southern side at Bowna Waters

1080-413: A major two-level (and at one point, three-level) roadway in the downtown area, are being rebuilt with a designed service life of 100 years. Virtually all roads require some form of maintenance before they come to the end of their service life. Pro-active agencies use pavement management techniques to continually monitor road conditions and schedule preventive maintenance treatments as needed to prolong

1188-402: A number of both historic paddle steamers and newer boats offering cruises ranging from half an hour to five days. The Murray River has been a significant barrier to land-based travel and trade. Many of the ports for transport of goods along the Murray have also developed as places to cross the river, either by bridge or ferry. The first bridge to cross the Murray, which was built in 1869, is in

1296-593: A river in Southeastern Australia . It is Australia's longest river at 2,508 km (1,558 mi) extent. Its tributaries include five of the next six longest rivers of Australia (the Murrumbidgee , Darling , Lachlan , Warrego and Paroo Rivers ). Together with that of the Murray, the catchments of these rivers form the Murray–Darling basin , which covers about one-seventh the area of Australia. It

1404-428: A road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which includes "bridges, tunnels, supporting structures, junctions, crossings, interchanges, and toll roads, but not cycle paths". The Eurostat , ITF and UNECE Glossary for Transport Statistics Illustrated defines

1512-494: A road as a "Line of communication (traveled way) open to public traffic, primarily for the use of road motor vehicles, using a stabilized base other than rails or air strips. [...] Included are paved roads and other roads with a stabilized base, e.g. gravel roads. Roads also cover streets, bridges, tunnels, supporting structures, junctions, crossings and interchanges. Toll roads are also included. Excluded are dedicated cycle lanes." The 1968 Vienna Convention on Road Traffic defines

1620-494: A road as the entire surface of any way or street open to public traffic. In urban areas roads may diverge through a city or village and be named as streets, serving a dual function as urban space easement and route. Modern roads are normally smoothed, paved, or otherwise prepared to allow easy travel . Part 2, Division 1, clauses 11–13 of the National Transport Commission Regulations 2006 defines

1728-519: A road in Australia as 'an area that is open to or used by the public and is developed for, or has as one of its main uses, the driving or riding of motor vehicles.' Further, it defines a shoulder (typical an area of the road outside the edge line, or the curb) and a road-related area which includes green areas separating roads, areas designated for cyclists and areas generally accessible to the public for driving, riding or parking vehicles. In New Zealand,

1836-426: A sandbank. During its year of launch, the boiler of Etona gave way, being replaced at a cost of £87. The Murray was plagued by "snags", fallen trees submerged in the water, and considerable efforts were made to clear the river of these threats to shipping by using barges equipped with steam-driven winches . In recent times, efforts have been made to restore many of these snags by placing dead gum trees back into

1944-546: A series of barrages was built near the Murray Mouth to stop seawater entering the lower part of the river during low flow periods. They are the Goolwa Barrage, with a length of 632 metres (2,073 ft); Mundoo Channel Barragel 800 metres (2,600 ft); Boundary Creek Barragel 243 metres (797 ft); Ewe Island Barrage, 853 metres (2,799 ft); and Tauwitchere Barrage, 3.6 kilometres (2.2 mi). These dams inverted

2052-521: A similar number of barges were working the river in season. River transport began to decline once the railways touched the Murray at numerous points. The unreliable levels made it impossible for boats to compete with the rail and later road transport . However, the river still carries pleasure boats along its entire length. Today, most traffic on the river is recreational. Small private boats are used for water skiing and fishing. Houseboats are common, both commercial for hire and privately owned. There are

2160-518: A spear. However, the shock to the fish was so great it launched him forward in a straight line to a place called Peindjalang, near Tailem Bend . Eager to rectify his failure to catch his prey, the hunter and his two wives (sometimes the escaped sibling wives of Waku and Kanu) hurried on, and took positions high on the cliff on which Tailem Bend now stands. They sprung an ambush on Pondi only to fail again. Ngurunderi set off in pursuit again but lost his prey as Pondi dived into Lake Alexandrina. Ngurunderi and

2268-432: Is 40 years for new bitumen and concrete pavement. Maintenance is considered in the whole life cost of the road with service at 10, 20 and 30-year milestones. Roads can be and are designed for a variety of lives (8-, 15-, 30-, and 60-year designs). When pavement lasts longer than its intended life, it may have been overbuilt, and the original costs may have been too high. When a pavement fails before its intended design life,

2376-433: Is a non-destructive method of solving this problem and is usually employed with other concrete pavement restoration methods including patching and diamond grinding. The technique restores support to concrete slabs by filing small voids that develop underneath the concrete slab at joints, cracks or the pavement edge. The process consists of pumping a cementitious grout or polyurethane mixture through holes drilled through

2484-731: Is actually on the Mitta Mitta River upstream of Lake Hume (completed 1979). The Murray also receives water from the complex dam and pipeline system of the Snowy Mountains Scheme . An additional reservoir was proposed in the 1960s at Chowilla Dam , which was to have been built in South Australia and would have flooded land mostly in Victoria and New South Wales. It was cancelled in favour of building Dartmouth Dam due to costs and concerns relating to increased salinity. From 1935 to 1940

2592-487: Is also common. Some road fixtures such as road signs and fire hydrants are designed to collapse on impact. Light poles are designed to break at the base rather than violently stop a car that hits them. Highway authorities may also remove larger trees from the immediate vicinity of the road. During heavy rains, if the elevation of the road surface is not higher than the surrounding landscape, it may result in flooding. Speed limits can improve road traffic safety and reduce

2700-485: Is another common procedure used to locate voids. It is recommended to do this testing at night as during cooler temperatures, joints open, aggregate interlock diminishes and load deflections are at their highest. Ground penetrating radar pulses electromagnetic waves into the pavement and measures and graphically displays the reflected signal. This can reveal voids and other defects. The epoxy/core test, detects voids by visual and mechanical methods. It consists of drilling

2808-418: Is discovered it is removed, moisture content is managed and replaced with standard fill compacted to meet the design requirements (generally 90–95% relative compaction). Blasting is not frequently used to excavate the roadbed as the intact rock structure forms an ideal road base. When a depression must be filled to come up to the road grade the native bed is compacted after the topsoil has been removed. The fill

2916-540: Is in most places quite close to the previous highway, most of which remains for local use. This section also included the abandoning of the route over the Mundoonen Range which, when it was rebuilt in the 1960s, was designed to be duplicated. Between Conroys Gap and Coolac , most of the earlier alignment was replaced in 1983 and 1996 by realignment associated with dual carriageway construction, although sections such as that south of Connors Creek were rebuilt in 1979 with

3024-581: Is known to have sold his share in the Bungaree Station , which he founded with his brothers, and relocated alongside the Murray at a site near Moorundie . In 1852, Francis Cadell , in preparation for the launch of his steamer service, explored the river in a canvas boat, travelling 1,300 miles (2,100 km) downstream from Swan Hill . In 1858, while acting as Minister of Land and Works for New South Wales, Irish nationalist and founder of Young Ireland , Charles Gavan Duffy , founded Carlyle Township on

3132-451: Is made by the "compacted layer method" where a layer of fill is spread then compacted to specifications, under saturated conditions. The process is repeated until the desired grade is reached. General fill material should be free of organics , meet minimum California bearing ratio (CBR) results and have a low plasticity index . The lower fill generally comprises sand or a sand-rich mixture with fine gravel, which acts as an inhibitor to

3240-412: Is often portrayed as a man) on rafts (or lala ) made from red gums and continually launched spears at his target. But Pondi was a wily prey and carved a weaving path, carving out the river's various tributaries. Ngurunderi was forced to beach his rafts, and often create new ones as he changed from reach to reach of the river. At Kobathatang, Ngurunderi finally got lucky and struck Pondi in the tail with

3348-564: Is primarily due to environmental effects such as frost heaves , thermal cracking and oxidation often contribute, however accumulated damage from vehicles also contributes. According to a series of experiments carried out in the late 1950s, called the AASHO Road Test , it was empirically determined that the effective damage done to the road is roughly proportional to the fourth power of axle weight . A typical tractor-trailer weighing 80,000 pounds (36.287 t ) with 8,000 pounds (3.629 t) on

3456-517: Is some ambiguity between the terms highway and road . For the purposes of the English law , Highways Act 1980 , which covers England and Wales but not Scotland or Northern Ireland , road is "any length of highway or of any other road to which the public has access, and includes bridges over which a road passes". This includes footpaths, bridleways and cycle tracks, and also road and driveways on private land and many car parks. Vehicle Excise Duty ,

3564-410: Is taken to preserve reference Benchmarks Roads are designed and built for primary use by vehicular and pedestrian traffic. Storm drainage and environmental considerations are a major concern. Erosion and sediment controls are constructed to prevent detrimental effects. Drainage lines are laid with sealed joints in the road easement with runoff coefficients and characteristics adequate for

3672-542: Is the border between New South Wales and Victoria – specifically at the top of the bank of the Victorian side of the river. In a 1980 judgement, the High Court of Australia ruled on the question as to which state had jurisdiction in the unlawful death of a man who was fishing by the river's edge on the Victorian side of the river. This boundary definition can be ambiguous, since the river changes its course over time, and some of

3780-546: Is the native material underneath a constructed road. Road construction requires the creation of an engineered continuous right-of-way or roadbed , overcoming geographic obstacles and having grades low enough to permit vehicle or foot travel , and may be required to meet standards set by law or official guidelines. The process is often begun with the removal of earth and rock by digging or blasting, construction of embankments , bridges and tunnels , and removal of vegetation (this may involve deforestation ) and followed by

3888-482: Is the point at which the Murray River empties into the sea, and the interaction between its shallow, shifting and variable currents and the open sea can be complex and unpredictable. During the peak period of Murray River commerce (roughly 1855 to 1920), it presented a major impediment to the passage of goods and produce between Adelaide and the Murray settlements, and many vessels foundered or were wrecked there. Since

3996-559: Is usually stripped and stockpiled nearby for rehabilitation of newly constructed embankments along the road. Stumps and roots are removed and holes filled as required before the earthwork begins. Final rehabilitation after road construction is completed will include seeding, planting, watering and other activities to reinstate the area to be consistent with the untouched surrounding areas. Processes during earthwork include excavation, removal of material to spoil, filling, compacting, construction and trimming. If rock or other unsuitable material

4104-502: Is widely considered Australia's most important irrigated region. The Murray rises in the Australian Alps , draining the western side of Australia's highest mountains, then meanders northwest across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows into South Australia . From an east–west direction it turns south at Morgan for its final 315 km (196 mi), reaching

4212-406: The land zoning and storm water system. Drainage systems must be capable of carrying the ultimate design flow from the upstream catchment with approval for the outfall from the appropriate authority to a watercourse , creek , river or the sea for drainage discharge. A borrow pit (source for obtaining fill, gravel, and rock) and a water source should be located near or in reasonable distance to

4320-401: The river banks have been modified. For 11 km (6.8 mi) west of the line of longitude 141°E, the border is between Victoria and South Australia, in the middle of the river. The discrepancy was caused during the 1840s, when the border was originally surveyed, by an east–west miscalculation of 3.72 kilometres (2.31 miles). West of this sector, the Murray is entirely within

4428-517: The river red gum . The health of the Murray has declined significantly since European settlement, particularly through regulation of its flows. Extreme droughts between 2000 and 2007 put significant stress on river red gum forests, leading to mounting concern over their long-term survival. The Murray has also flooded on occasion. The most significant was the flood of 1956 : lasting for up to six months, it inundated many towns on its lower reaches in South Australia. Between 2.5 and 0.5 million years ago,

4536-461: The Cadell Fault. About 25,000 years ago, displacement occurred along this fault, raising its eastern edge, which runs north–south, 8 to 12 m (26 to 39 ft) above the floodplain. This created a complex series of events. A section of the original Murray River channel immediately behind the fault was rendered abandoned (it exists today as an empty channel known as Green Gully). The Goulburn River

4644-509: The Hume Highway and takes on the conditions of an urban highway . Many of the superseded sections of the Hume Highway are of historical interest as they provide insights into the small historical towns which have since been bypassed . In the past when the highway passed through these towns, many were thriving centres. Many of the superseded sections of the highway still form the main access roads into and through these towns. One section of

4752-491: The Murray River, after his close friend, Scottish historian and essayist Thomas Carlyle . Included in the township were "Jane Street", named in honour of Carlyle's wife Jane Carlyle and "Stuart-Mill Street" in honour of political philosopher John Stuart Mill In 1858, the Government Zoologist , William Blandowski , together with Gerard Krefft , explored the lower reaches of the Murray and Darling rivers, compiling

4860-422: The Murray and its tributaries by destroying aquatic plants and permanently raising turbidity . Carp is the most common species, and can be found in all segments of the river. Four large reservoirs were built along the Murray. In addition to Lake Victoria (completed late 1920s), these are Lake Hume near Albury-Wodonga (completed 1936), Lake Mulwala at Yarrawonga (completed 1939), and Lake Dartmouth , which

4968-458: The Murray persists in numerous forms in various language groups that inhabit the enormous area spanned by the Murray system. The Wotojobaluk people of Victoria tell of Totyerguil from the area now known as Swan Hill , who ran out of spears while chasing Otchtout the cod. Roonka Flat , near Blanchetown , was a site of occupation since at least 7000BC. The first Europeans to encounter the river were Hamilton Hume and William Hovell , who crossed

5076-466: The Murray short-necked turtle, broad-clawed yabbies and the large-clawed Macrobrachium shrimp, in addition to aquatic species more widely distributed through Southeastern Australia such as common long-necked turtles, common yabbies , the small claw-less paratya shrimp, water rats and platypus . The Murray crayfish , an endangered species, was able to increase its numbers thanks to scientists. The Murray also supports fringeing corridors and forests of

5184-473: The Murray terminated in a vast freshwater lake – Lake Bungunnia – formed by earth movements that blocked the river near Swan Reach . At its maximum extent, Lake Bungunnia covered 33,000 km (12,741 sq mi), extending to near the Menindee Lakes in the north and to near Boundary Bend in the south. The draining of Lake Bungunnia occurred approximately 600,000 years ago. Deep clays deposited by

5292-669: The Old Hume Highway, called the Yass Valley Way , travels through Yass in southern New South Wales. The section of the Hume Highway between the Cross Roads, at Prestons on Sydney's southwestern fringe, and the Medway Rivulet near Berrima , was completely superseded in the period 1973–1992 by a new route built as a freeway. Most of the highway route between Breadalbane, west of Goulburn , and Derringullen Creek, west of Yass ,

5400-513: The Red Gum forests, actually travels through the Edward River channel. The Murray has not had enough flow power to naturally enlarge The Barmah Choke and The Narrows to increase the amount of water they can carry. The Cadell Fault is quite noticeable as a continuous, low, earthen embankment as one drives into Barmah from the west, although to the untrained eye it may appear man-made. The Murray Mouth

5508-422: The ability to flow into or expand to fill small voids. Colloidal mixing equipment is necessary to use the pozzolan-cement grouts. The contractor must place the grout using a positive-displacement injection pump or a non-pulsing progressive cavity pump. A drill is also necessary but it must produce a clean hole with no surface spalling or breakouts. The injection devices must include a grout packer capable of sealing

5616-491: The advent of large-scale river regulation , the waters at the Murray Mouth are almost invariably slow and shallow. As of 2010 , the Murray River system received 58 per cent of its natural flow; the figure varies considerably. The border between Victoria and New South Wales (NSW) lies along the top of the southern or left bank of the Murray River. The Murray forms part of the 3,750 km (2,330 mi) long combined Murray–Darling river system that drains most of

5724-433: The area. These conditions are perfect for River Red Gums , which rapidly formed forests in the area. Thus the displacement of the Cadell Fault 25,000 BP led directly to the formation of the famous Barmah River Red Gum Forests. The Barmah Choke and The Narrows restrict the amount of water that can travel down this part of the Murray. In times of flood and high irrigation flows the majority of the water, in addition to flooding

5832-521: The average US motorist pays about $ 335/year. In contrast, the average motorist pays about $ 171/year in road maintenance taxes (based on 600 gallons/year and $ 0.285/gallon tax). Distress and serviceability loss on concrete roads can be caused by loss of support due to voids beneath the concrete pavement slabs. The voids usually occur near cracks or joints due to surface water infiltration . The most common causes of voids are pumping, consolidation, subgrade failure and bridge approach failure. Slab stabilization

5940-538: The definition of a road is broad in common law where the statutory definition includes areas the public has access to, by right or not. Beaches, publicly accessible car parks and yards (even if privately owned), river beds, road shoulders (verges), wharves and bridges are included. However, the definition of a road for insurance purposes may be restricted to reduce risk. In the United Kingdom The Highway Code details rules for "road users", but there

6048-465: The design structural capacity, stop erosion or eliminate faulting. It does, however, restore the slab support, therefore, decreasing deflections under the load. Stabilization should only be performed at joints and cracks where the loss of support exists. Visual inspection is the simplest manner to find voids. Signs that repair is needed are transverse joint faulting, corner breaks and shoulder drop off and lines at or near joints and cracks. Deflection testing

6156-562: The driest continents on Earth, the Murray has significant cultural relevance to Aboriginal Australians . According to the people of Lake Alexandrina , the Murray was created by the tracks of the Great Ancestor, Ngurunderi, as he pursued Pondi, the Murray Cod . The chase originated in the interior of New South Wales. Ngurunderi pursued the fish (who, like many totem animals in Aboriginal myths,

6264-532: The early 2000s, dredging machines have operated at the Murray Mouth for 24 hours a day, moving sand from the channel to maintain a minimal flow from the sea and into the Coorong's lagoon system. Without the dredging, the mouth would silt up and close, cutting the supply of fresh sea-water into the Coorong National Park, which would then warm up, stagnate and die. Being one of the major river systems on one of

6372-521: The earthworks being done for a second carriageway, which was subsequently built in 1994. The current route of the highway between Tumblong and Tarcutta is the third route of the highway in this location. The original route led west from Tumblong along the Murrumbidgee River , before turning south over difficult country, crossing what is now the Sturt Highway and rejoining the current route of

6480-684: The eastern edge of Lake Alexandrina , which fluctuates in salinity . The water then flows through several channels around Hindmarsh Island and Mundoo Island . There it is joined by lagoon water from The Coorong to the south-east before emptying into the Great Australian Bight (often referenced on Australian maps as the Southern Ocean ) through the Murray Mouth , 10 km (6.2 mi) east of Goolwa South . Despite discharging considerable volumes of water at times, particularly before

6588-441: The first pathways were the trails made by animals has not been universally accepted; in many cases animals do not follow constant paths. Some believe that some roads originated from following animal trails. The Icknield Way may exemplify this type of road origination, where human and animal both selected the same natural line. By about 10,000 BC human travelers used rough roads/pathways. In transport engineering , subgrade

6696-402: The first track, the route of what is now the Hume Highway has been the main road link between the Australia's two largest cities – Sydney and Melbourne . Since February 1960 a freeway standard of road has been developed along this route. Where the alignment of the original road is reasonably flat and straight it has been duplicated and retained for traffic in one direction. In some locations

6804-499: The first trips being made by two boats from South Australia on the spring flood of 1853. The Lady Augusta , captained by Francis Cadell , reached Swan Hill while another, Mary Ann , captained by William Randell , reached Moama (near Echuca ). In 1855 a steamer carrying gold-mining supplies reached Albury but Echuca was the usual turn-around point, though small boats continued to link with up-river ports such as Tocumwal , Wahgunyah and Albury. The arrival of steamboat transport

6912-416: The functional condition of the road while reducing the need for routing maintenance, leading to extended service life without increasing structural capacity. Older concrete pavements that develop faults can be repaired with a dowel bar retrofit , in which slots are cut in the pavement at each joint, and dowel bars are placed in the slots, which are then filled with concrete patching material. This can extend

7020-464: The growth of plants or other vegetable matter. The compacted fill also serves as lower-stratum drainage. Select second fill ( sieved ) should be composed of gravel , decomposed rock or broken rock below a specified particle size and be free of large lumps of clay . Sand clay fill may also be used. The roadbed must be "proof rolled" after each layer of fill is compacted. If a roller passes over an area without creating visible deformation or spring

7128-559: The highway as Lower Tarcutta Road. This was replaced in December 1938 by the first Tumblong deviation, to the east of the current route. The main features of this section of the highway were a deep, narrow cutting and the reinforced concrete bowstring arch bridge over Hillas Creek. This has been preserved, and is visible on the western side of the highway close to the interchange with the Snowy Mountains Highway . North of Albury ,

7236-404: The highway system from traffic collisions. On neighborhood roads traffic calming , safety barriers , pedestrian crossings and cycle lanes can help protect pedestrians, cyclists, and drivers. Lane markers in some countries and states are marked with Cat's eyes or Botts dots. Botts dots are not used where it is icy in the winter, because frost and snowplows can break the glue that holds them to

7344-580: The hole. The injection device must also have a return hose or a fast-control reverse switch, in case workers detect slab movement on the uplift gauge. The uplift beam helps to monitor the slab deflection and has to have sensitive dial gauges. Also called joint and crack repair, this method's purpose is to minimize infiltration of surface water and incompressible material into the joint system. Joint sealants are also used to reduce dowel bar corrosion in concrete pavement restoration techniques. Successful resealing consists of old sealant removal, shaping and cleaning

7452-419: The inland of Victoria, New South Wales and the southern part of Queensland. The Murray carries only a small fraction of the water of comparably sized rivers in other parts of the world, and with great annual variability of its flow. It has dried up completely during extreme droughts on three occasions since official record-keeping began. More often, a sandbar formed at the mouth and stopped the flow. The Murray

7560-486: The intervening stretch of the river a series of locks and weirs were built. These were originally proposed to support navigation even in times of low water, but riverborne transport was already declining due to improved highway and railway systems. The disruption of the river's natural flow, run-off from agriculture, and the introduction of pest species such as the European carp has led to serious environmental damage along

7668-491: The irrigation has led to dryland salinity that now threatens the agricultural industries. In 2006, the Government of South Australia released a plan to investigate the construction of controversial Wellington Weir . Lock 1 was completed near Blanchetown in 1922. Torrumbarry weir downstream of Echuca began operating in December 1923. Of the several locks that were proposed, only thirteen were completed; Locks 1 to 11 on

7776-656: The lake are evident in cliffs around Chowilla in South Australia. Considerably higher rainfall would have been required to keep such a lake full; the draining of Lake Bungunnia appears to have marked the end of a wet phase in the history of the Murray–Darling Basin and the onset of widespread arid conditions similar to today. A species of Neoceratodus lungfish existed in Lake Bungunnia; today Neoceratodus lungfish are only found in several Queensland rivers. The noted Barmah River red gum forests owe their existence to

7884-404: The laying of pavement material. A variety of road building equipment is employed in road building. After design, approval , planning , legal, and environmental considerations have been addressed alignment of the road is set out by a surveyor . The radii and gradient are designed and staked out to best suit the natural ground levels and minimize the amount of cut and fill. Great care

7992-518: The life of the concrete pavement for 15 years. Failure to maintain roads properly can create significant costs to society. A 2009 report released by the American Association of State Highway and Transportation Officials estimated that about 50% of the roads in the US are in bad condition, with urban areas worse. The report estimates that urban drivers pay an average of $ 746/year on vehicle repairs while

8100-609: The lifespan of their roads. Technically advanced agencies monitor the road network surface condition with sophisticated equipment such as laser/inertial profilometers . These measurements include road curvature , cross slope , asperity , roughness , rutting and texture . Software algorithms use this data to recommend maintenance or new construction. Maintenance treatments for asphalt concrete generally include thin asphalt overlays, crack sealing, surface rejuvenating, fog sealing, micro milling or diamond grinding and surface treatments . Thin surfacing preserves, protects and improves

8208-515: The new carriageway is not always constructed directly alongside the existing carriageway. Roads that are intended for use by a particular mode of transport can be reallocated for another mode of transport, i.e. by using traffic signs . For instance, in the ongoing road space reallocation effort, some roads (particularly in city centers) which are intended for use by cars are increasingly being repurposed for cycling and/or walking . Like all structures, roads deteriorate over time. Deterioration

8316-466: The number of road traffic casualties from traffic collisions . In their World report on road traffic injury prevention report, the World Health Organization (WHO) identify speed control as one of various interventions likely to contribute to a reduction in road casualties. Road conditions are the collection of factors describing the ease of driving on a particular stretch of road, or on

8424-964: The old route terminates at dead end. On the northern side the old route is now a road that services local farms, including Willow Park, with the remainder of the old route now being part of private property and inaccessible to road traffic. Parts of the old route are visible when the waters of Lake Hume are low from the air and satellite imagery (Google Map) Road There are many types of roads , including parkways , avenues , controlled-access highways (freeways, motorways, and expressways), tollways , interstates , highways , thoroughfares , and local roads. The primary features of roads include lanes , sidewalks (pavement), roadways (carriageways), medians , shoulders , verges , bike paths (cycle paths), and shared-use paths . Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines

8532-459: The original road has been replaced by a dual carriageway road right beside the original road. In other locations the new road deviates from the original by many kilometres. In both Victoria and New South Wales since 2013, 100% of the Hume Highway has been upgraded to at least dual carriageway standard and is called the Hume Freeway . In both metropolitan Sydney and Melbourne, the road reverts to

8640-506: The owner may have excessive repair and rehabilitation costs. Some asphalt pavements are designed as perpetual pavements with an expected structural life in excess of 50 years. Many asphalt pavements built over 35 years ago, despite not being specifically designed as a perpetual pavement, have remained in good condition long past their design life. Many concrete pavements built since the 1950s have significantly outlived their intended design lives. Some roads like Chicago 's Wacker Drive ,

8748-474: The patterns of the river's natural flow from the original winter-spring flood and summer-autumn dry to the present low level through winter and higher during summer. These changes ensured the availability of water for irrigation and made the Murray Valley Australia's most productive agricultural region, but have seriously disrupted the life cycles of many ecosystems both inside and outside the river, and

8856-418: The pavement performance, reduce construction costs and decrease maintenance. The completed roadway is finished by paving or left with a gravel or other natural surface. The type of road surface is dependent on economic factors and expected usage. Safety improvements such as traffic signs , crash barriers , raised pavement markers and other forms of road surface marking are installed. According to

8964-569: The presence or absence of a made road has nothing to do with the distinction. Another legal view is that while a highway historically included footpaths , bridleways , driftways, etc., it can now be used to mean those ways that allow the movement of motor vehicles , and the term rights of way can be used to cover the wider usage. In the United States, laws distinguish between public roads , which are open to public use, and private roads , which are privately controlled. The assertion that

9072-472: The public so that drivers going through a particular area can be aware of hazards that may exist in that area. News agencies, in turn, rely on tips from area residents with respect to certain aspects of road conditions in their coverage area. Murray River The Murray River (in South Australia: River Murray ) ( Ngarrindjeri : Millewa , Yorta Yorta : Dhungala ( Tongala )) is

9180-511: The remaining length of the Murray to finally reach Lake Alexandrina and the river's mouth. The vicinity of the Murray Mouth was explored more thoroughly by Captain Collet Barker in 1831. The first three settlers on the Murray River are known to have been James Collins Hawker (explorer and surveyor) along with Edward John Eyre (explorer and later Governor of Jamaica ) plus E.B. Scott (onetime superintendent of Yatala Labour Prison ). Hawker

9288-418: The reservoir, installing the backer rod and installing the sealant. Sawing, manual removal, plowing and cutting are methods used to remove the old sealant. Saws are used to shape the reservoir. When cleaning the reservoir, no dust, dirt or traces of old sealant should remain. Thus, it is recommended to water wash, sand-blast and then air blow to remove any sand, dirt or dust. The backer rod installation requires

9396-426: The river channel is unusually narrow), before entering into the proper Murray River channel again. The primary result of the Cadell Fault – that the west-flowing water of the Murray River strikes the north-south fault and diverts both north and south around the fault in the two main channels (Edward and ancestral Goulburn) in addition to a fan of small streams, and regularly floods a large amount of low-lying country in

9504-615: The river promoted an expansion of farming and led ultimately to the development of irrigation areas (including the Murrumbidgee Irrigation Area ). In 1915, the three Murray states – New South Wales, Victoria, and South Australia – signed the River Murray Agreement which proposed the construction of storage reservoirs in the river's headwaters as well as at Lake Victoria near the South Australian border. Along

9612-610: The river where Albury now stands in 1824: Hume named it the Hume River after his father. In 1830, Captain Charles Sturt reached the river after travelling down its tributary the Murrumbidgee River and named it the Murray River in honour of the then British Secretary of State for War and the Colonies , Sir George Murray , not realising it was the same river that Hume and Hovell had encountered further upstream. Sturt continued down

9720-595: The river's length. There are widespread concerns that the river will be unusably salty in the medium to long term – a serious problem given that the Murray supplies 40 per cent of the water supply for Adelaide . Efforts to alleviate the problems have proceeded but disagreement between various groups has hampered progress. Introduced fish species such as carp , gambusia , weather loach , redfin perch , brown trout , and rainbow trout have also had serious negative effects on native fish. The most pernicious are carp, which have contributed to environmental degradation of

9828-527: The river. The primary purpose of this is to provide habitat for fish species whose breeding grounds and shelter were eradicated by the removal of the snags. Author E.J. Brady chronicled an eventful journey downriver in a small motor boat from Albury to the coast in 1911 in River Rovers. The volume and value of river trade made Echuca Victoria's second port and in the decade from 1874 it underwent considerable expansion. By this time up to thirty steamers and

9936-494: The road conditions". Specific aspects of road conditions can be of particular importance for particular purposes. For example, for autonomous vehicles such as self-driving cars , significant road conditions can include "shadowing and lighting changes, road surface texture changes, and road markings consisting of circular reflectors, dashed lines, and solid lines". Various government agencies and private entities, including local news services, track and report on road conditions to

10044-399: The road construction area may be marked for retention. These protected trees should not have the topsoil within the area of the tree's drip line removed and the area should be kept clear of construction material and equipment. Compensation or replacement may be required if a protected tree is damaged. Much of the vegetation may be mulched and put aside for use during reinstatement. The topsoil

10152-512: The road construction site. Approval from local authorities may be required to draw water or for working (crushing and screening) of materials for construction needs. The topsoil and vegetation is removed from the borrow pit and stockpiled for subsequent rehabilitation of the extraction area. Side slopes in the excavation area not steeper than one vertical to two horizontal for safety reasons. Old road surfaces, fences, and buildings may need to be removed before construction can begin. Trees in

10260-473: The road, although they can be embedded in short, shallow trenches carved in the roadway, as is done in the mountainous regions of California. For major roads risk can be reduced by providing limited access from properties and local roads, grade separated junctions and median dividers between opposite-direction traffic to reduce the likelihood of head-on collisions. The placement of energy attenuation devices (e.g. guardrails, wide grassy areas, sand barrels)

10368-404: The roads of a particular locality, including the quality of the pavement surface , potholes , road markings, and weather . It has been reported that "[p]roblems of transportation participants and road conditions are the main factors that lead to road traffic accidents". It has further been specifically noted that "weather conditions and road conditions are interlinked as weather conditions affect

10476-406: The section is deemed to comply. Geosynthetics such as geotextiles , geogrids , and geocells are frequently used in the various pavement layers to improve road quality. These materials and methods are used in low-traffic private roadways as well as public roads and highways. Geosynthetics perform four main functions in roads: separation, reinforcement, filtration, and drainage; which increase

10584-437: The slab. The grout can fill small voids beneath the slab and/or sub-base. The grout also displaces free water and helps keep water from saturating and weakening support under the joints and slab edge after stabilization is complete. The three steps for this method after finding the voids are locating and drilling holes, grout injection and post-testing the stabilized slabs. Slab stabilization does not correct depressions, increase

10692-571: The state of South Australia. Major settlements along the course of the river, from its source to the Southern Ocean, and their populations from the 2016 Australian census are as follows. The Murray and its tributaries support a variety of river life adapted to its vagaries. This includes native fish such as the famous Murray cod , trout cod , golden perch , Macquarie perch , silver perch , eel-tailed catfish , Australian smelt and western carp gudgeon , as well as other aquatic species such as

10800-476: The steer axle and 36,000 pounds (16.329 t) on both of the tandem axle groups is expected to do 7,800 times more damage than a passenger vehicle with 2,000 pounds (0.907 t) on each axle. Potholes on roads are caused by rain damage and vehicle braking or related construction work. Pavements are designed for an expected service life or design life . In some parts of the United Kingdom the standard design life

10908-434: The stretch downstream of Mildura , Lock 15 at Euston and Lock 26 at Torrumbarry . Construction of the remaining weirs purely for navigation purposes was abandoned in 1934. The last lock to be completed was Lock 15, in 1937. Lock 11, just downstream of Mildura, creates a 100-kilometre (62 mi) long lock pool that aided irrigation pumping from Mildura and Red Cliffs . Each lock has a navigable passage next to it through

11016-468: The town of Murray Bridge, formerly called Edwards Crossing. To distinguish this bridge from the many others that span the Murray River, this bridge is known as Murray River road bridge, Murray Bridge Tolls applied on South Australian ferries until abolished in November 1961. Small-scale pumping plants began drawing water from the Murray in the 1850s and the first high-volume plant was constructed at Mildura in 1887. The introduction of pumping stations along

11124-409: The weir, which is opened during periods of high river flow, when there is too much water for the lock. The weirs can be completely removed, and the locks completely covered by water during flood conditions. Lock 11 is unique in that the lock was built inside a bend of the river, with the weir in the bend itself. A channel was dug to the lock, creating an island between it and the weir. The weir is also of

11232-400: The women settled on the shore, only to suffer bad luck with fishing, being plagued by a water fiend known as Muldjewangk . They later moved to a more suitable spot at the site of present-day Ashville . The twin summits of Mount Misery are said to be the remnants of his rafts; they are known as Lalangengall or the two watercraft . This story of a hunter pursuing a Murray cod that carved out

11340-597: Was dammed by the southern end of the fault to create a natural lake. The Murray River flowed to the north around the Cadell Fault, creating the channel of the Edward River which exists today and through which much of the Murray's waters still flow. Then the natural dam on the Goulburn River failed, the lake drained, and the Murray changed its course to the south and started to flow through the smaller Goulburn River channel, creating "The Barmah Choke" and "The Narrows" (where

11448-428: Was launched as a mission steamer, replacing an earlier steam launch, also named Etona , which had been operating on the Murray since 1891. The vessel was based at Murray Bridge , and operated between Goolwa and the Victorian border, stopping at towns such as Mannum , Morgan and Renmark as well as isolated settlements and workcamps. The forepart of the vessel was used a chapel fitted with an altar and organ, with

11556-584: Was replaced during 1994. This included a bypassing of the Cullerin Range. The previous route of the highway over the Cullerin Range was itself a deviation built in 1920, using sections of railway formation abandoned several years earlier when the Main Southern railway line was deviated at the time it was duplicated. The deviations were an attempt to ease the gradients against heavily laden Sydney-bound steam trains. The Breadalbane–Derringullen Creek deviation

11664-455: Was welcomed by pastoralists who had been suffering from a shortage of transport due to the demands of the gold fields. By 1860 a dozen steamers were operating in the high water season along the Murray and its tributaries. Once the railway reached Echuca in 1864, the bulk of the woolclip from the Riverina was transported via river to Echuca and then south to Melbourne. The steam paddleship Etona
