79-598: The Sheffield Parkway is a major dual carriageway which runs between the City of Sheffield and junction 33 of the M1 in South Yorkshire , England . The 5.5-mile (8.9 km) road was opened in 1974. The route runs east of the City, connecting Park Square in the city centre with the inner ring road , outer ring road and out to the M1 motorway at junction 33. It passes the districts of

158-407: A divided highway ( AmE ) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways , freeways, etc., rather than dual carriageways. A road without a central reservation is known as

237-428: A single carriageway regardless of how many lanes there are. Dual carriageways have improved road traffic safety over the years and over single carriageways and typically have higher speed limits as a result. In some places, express lanes and local or collector lanes are used within a local-express-lane system to provide more capacity and to smooth out traffic flows for longer-distance travel. A very early (perhaps

316-501: A 'motorway/freeway' standard divided road. Most states only declare a divided road as a 'motorway' or 'freeway' if access is completely controlled . Speed limits are usually 100 km/h or 110 km/h. Belt Parkway The Belt Parkway is the name given to a series of controlled-access parkways that form a belt-like circle around the New York City boroughs of Brooklyn and Queens . The Belt Parkway comprises three of

395-414: A broken line indicating passing zones and a solid line indicating no passing zones and solid white baseline shoulder stripes. On undivided roads with more than one lane in each direction, the center is normally marked with a double solid line. The double solid stripe denotes that it is illegal to pass on the other side of the center line. Multilane one-way carriageways use broken white lines between lanes;

474-473: A built up area is indicated by the presence of street lights; on lit dual carriageways that are not considered to be in a built-up area, the speed limit will be clarified with intermittent signs. Although in Ireland the term dual carriageway technically applies to any road with physically separated lanes, it is usually used only to refer to those route sections that do not have a motorway designation. Most often it

553-567: A central median, usually fitted with guardrails. The most heavily used expressways in Croatia is the D10 road , connecting capital Zagreb to Vrbovec and Križevci . In the United States, this type of road may be called a divided highway, boulevard, parkway, expressway, freeway, or interstate, and has a grassy median or Jersey barrier separating the traffic directions. With few exceptions, all roads in

632-583: A decade before construction began, of turning Coney Island from an island into a peninsula. The Gowanus Parkway, in part replacing the demolished Fifth Avenue Line , was built as an elevated structure over Third and Hamilton Avenues in order to avoid the active docks and industrial areas including Sunset Park, Brooklyn . Like most parkways in New York State , the parkways comprising the Belt System were closed to commercial traffic, including any vehicle with

711-473: A freeway from the 1950s to 1970s. Opened to traffic in 1940, the 160-mile-long (260 km) Pennsylvania Turnpike was the first rural dual carriageway built in the United States. By 1955 several states had built dual carriageway freeways and turnpikes and in 1957 the Interstate Highway System began. Completed in 1994, the major highway system links all the major cities of the United States. In

790-597: A junction with the JFK Expressway and the airport. Crossing under the Van Wyck, the Belt continues east through multiple underpasses and overpasses before reaching exit 21A, westbound side, which services 150th Street and Rockaway Boulevard . Crossing under Guy R. Brewer Boulevard, the Belt passes exit 21B, which connects to Farmers Boulevard and Guy R. Brewer Boulevard. Exit 22 services Springfield Boulevard , where

869-467: A lack of funding elsewhere, partial controlled-access "expressways" and limited-mobility divided arterial roads are more common in the western provinces where there are no specially numbered systems of freeways. On some portions of Ontario 's 400-series highway network, the median may be either steel guardrail or an Ontario tall-wall barrier rather than an unpaved strip, particularly in urban areas. Some partial limited-access divided highways such as

948-498: A median barrier preventing left turns (motorists have to use a "turnabout" overpass to access exits on the opposing direction). Speed limits in Canada are usually 80 to 90 km/h on signalized divided highways and 100 to 120 km/h on freeways. In Australia, dual carriageways are referred to in some regions as divided roads, though there is no official terminology. Each state's road agency has its own definition of what constitutes

1027-490: A narrow strip of trees down the middle. In 1907 the Long Island Motor Parkway opened, and roughly 20% of it featured a semi-dual-carriageway design. The New York City Belt Parkway system, which was built between 1907 and 1934, also pioneered the same design. However the majority of it featured concrete or brick railings as lane dividers instead of grass medians. In the year of 1924 the first Italian autostrada

1106-593: A new standard was set to designate certain high-quality routes formally as "Expressways". Many roads such as the A1 , the A14 , the A19 and the A42 are built to a high quality, with grade-separated junctions, full barriers at roadside and central reservations and, in some cases, three lanes of traffic. They may still fall short of motorway standard in terms of hard shoulders, the height of overpasses or

1185-465: A non-passenger registration and all commercial trucking of any size. Originally even station wagons , which had "suburban" registrations, were excluded but they were later allowed, along with passenger-registered SUVs and vans. The Belt Parkway formed the southern portion of a system of parkways and highways that connected every borough except Staten Island . At its eastern end, the Belt Parkway became

1264-751: A point on Southern Parkway, just east of the Rockaway division of the Long Island Railroad in Queens. Work on the conversion of the Sunrise Highway into a genuine parkway is already under way. This will be known as Southern Parkway. Construction began in 1934. New highway designs were implemented, including dark main roads and lighter-colored entrance and exit ramps. The parkway first opened on June 29, 1940, with most of Cross Island, Southern, and Shore Parkway sections completed. A 12-mile (19 km) bike path along

1343-494: A precedent for future highways. Although it, like the first autostrada , did not feature a dual-carriageway design, it inspired the mass construction of future high-speed roadways. During the 1930s, Germany, Italy, and the Soviet Union began construction of a network of dual carriageway expressways. By 1942, Germany had over 3,200 km (2,000 mi) of dual carriageway roads, Italy had nearly 1,300 km (810 mi), and

1422-416: A result of their misjudging the speed of approaching traffic on the other carriageway when doing so. The majority of dual carriageway roads now have barriers. Some are heavy concrete obstructions which can bounce a vehicle back into the path of other traffic; others are made from steel ropes mounted on moderately weak posts, where the rope cuts into the vehicle body to slow the vehicle while keeping it against

1501-510: Is autovía (literally autoway ). All of them are government-owned and not tolled. First-generation autovías, built in the 1980s and early 1990s, were just duplications in parallel of existing roads, as shown in the photograph. Modern autovías are two carriageways built from scratch, leaving the old road they replace as an alternative route for pedestrians, bicycles and other non-motorized vehicles. Private properties may have direct access to an autovía, as well as bus stops and gas stations in

1580-399: Is national roads (roads with a route number prefix of N ; e.g. N8 ) that are built as or upgraded to dual carriageway. A number of non-national roads (for example, regional roads ) are dual carriageway, for example in urban areas near or in cities, or where the road was part of a national route. Dual carriageways of this class differ from motorways in a number of ways. The hard shoulder

1659-450: Is demarcated with a dashed yellow line (as opposed to an unbroken yellow line on motorways). The standard speed limit of 100 km/h (62 mph) for national routes usually applies (by default the limit is 80 km/h (50 mph) for non-national roads, even if dual carriageway). Local authorities have the power to apply a limit of up to 120 km/h (75 mph) as used on most motorways (The High Quality Dual Carriageway section of

Paralleling Third Avenue, the parkway turns west and crosses over the Long Island Rail Road Bay Ridge Branch , a freight-only line. Bypassing Bay Ridge, the Belt passes exit 1, which services 65th–67th Streets in Bay Ridge. Crossing south past Owl's Head Park , the parkway turns southward and enters Shore Road Park, paralleling

2133-493: The Hanlon Parkway and Black Creek Drive have stop-controlled at-grade intersections and private entrances, but have sufficient right-of-way to convert them to full freeways with interchanges if traffic warrants. There are also RIRO expressways , such as Highway 11 and a portion of Highway 35 , which are not full freeways since they allow access to existing properties, but traffic speeds are faster than regular roads due to

2212-676: The Mediterranean world . This influx of road activity necessitated the construction of a dual thoroughfare as the road approached the Porta Portese , the corresponding gate in the Aurelian Walls of Rome for the Via Portuensis . One claim for the first divided highway in the United States was Savery Avenue in Carver, Massachusetts , first built in 1860, where the two roadways were separated by

2291-686: The N1 between the end of the M1 and the border with Northern Ireland and the N25/N22 Ballincollig Bypass in Cork are the only route sections with such special limits). Traffic lights and junctions are permitted at grade on dual carriageways. For older sections of dual carriageway, this has resulted in fewer flyover junctions. Newer dual carriageway sections are usually near motorway standard, with grade-separated junctions, but may not be designated as motorways due to

2370-674: The autobahn network nor in the Bundesstraße network are given black on white signs, following the same sign code as high-speed dual carriageways—this is mostly seen on urban trunk roads. Italian Highway Code ( Codice della strada ) divides dual carriageways into three different classifications: Italian type-B and type-C roads do not follow a specific numbering criterion. They may be numbered as Strade Statali (SS; "state roads"), Strade Regionali (SR; "regional roads"), Strade Provinciali (SP; "provincial roads") or Strade Comunali (SC; "municipal roads"). The Spanish word for dual carriageway

The City of New York was vested title in an extension along Gravesend Bay to Bensonhurst Park, and is about to acquire the remaining rights-of-way up to Guilder Avenue, including sufficient land for

3081-512: The Southern Brooklyn section of the Belt Parkway opened in 1941. The construction of Belt Parkway entailed: All the original parkways, except the Gowanus, were built on grassy rights-of-way with trees, in a more green surrounding than most highways of their time. To build sections between exits 7 and 8 in the 1930s parts of Coney Island Creek were filled in, finishing the process, begun over

3318-656: The UK, although the term "dual carriageway" applies to any road with physically separated lanes, it is frequently used as a descriptive term for major routes built in this style. Such major dual carriageways usually have two lanes of traffic in each direction, with the lane nearest the centre being reserved for overtaking. Occasionally dual carriageways have only one lane in each direction, or more than two lanes each way (sometimes to permit easier overtaking of slower uphill traffic). Different speed limits apply on dual carriageway sections from those that apply on single carriageway sections of

3397-428: The barrier until it has stopped. Often on urban dual carriageways where the road has been converted from a four-lane single carriageway the central reservation will not be substantial: often just a small steel divider to save space. Turning right (that is, across the line of traffic heading in the opposite direction) is usually permitted only at specific locations. Often the driver will be required to turn left (away from

3476-455: The basis of their structure these roads have, comparable to the German autobahn , the legal foundation that no default speed limit exists (design speed 130 km/h), although the standard advisory speed limit ( German : Richtgeschwindigkeit ) still exists. Nevertheless, expressways are often given speed limit signs. Exit signs. At the moment some (blue) motorways have been taken out of

3555-682: The central reservation, the policy being to use a wider median instead. Crash barriers are now mandatory for such routes, and wire cabling or full crash barriers (depending on whether or not the route is a motorway, and median width) have been fitted to existing routes. Between 2000 and 2010, three major types of dual carriageway were built on national road schemes in Ireland: In Germany the term Autobahnähnliche Straße (motorway-like road) refers to roads that are similar to German autobahn in grade-separation and signage. Most of them are designated as Kraftfahrstraßen (expressways), which means that

It is proposed to acquire the rights-of-way for the extension of Guilder Avenue by means of a new parkway parallel to, and north of Emmons Avenue to the Marine Parkway extension, for which land is already in the possession of the City. It is proposed to carry the Circumferential Parkway from Flatbush Avenue where the Marine Parkway extension ends, along or near Jamaica Bay to

3792-435: The dual carriageway) in order to loop around to an access road that permits crossing the major road. Roundabouts on dual carriageways are relatively common, especially in cities or where the cost of a grade-separated junction would be prohibitive. Where space is even more limited, intersections may be controlled by traffic lights. Smaller residential roads adjoining urban dual carriageways may be blocked off at one end to limit

3871-514: The eastbound lanes. Exit 24B on the eastbound lanes connects also to Merrick Boulevard and 130th Avenue and on the westbound lanes connect Francis Lewis Boulevard. Just after crossing under 130th Avenue, the Belt passes exit 25A–B. At this interchange, the Laurelton Parkway segment ends, with exit 25A connecting to the western terminus of the Southern State Parkway and exit 25B servicing Elmont Road. At this interchange,

3950-597: The entire length featured a dual-carriageway design. In the early 1930s, it was extended southward all the way to Naples and northward to Florence. Most of the original routing was destroyed by the Allies in World War II. By 1930 several US and European cities had built dual-carriageway highways, mostly to control traffic jams and/or to provide bypass routes for traffic. In 1932 the first German autobahn opened between Cologne and Bonn. It ran 21 km (13 mi) and became

4029-615: The federally funded Interstate Highway System are fully controlled access divided highways known as freeways . A broader definition, expressways , includes both freeways and partial limited-access divided highways, and "expressway" is often used specifically to refer to the latter. United States Numbered Highways , state highways and other locally maintained highways may also be divided. Speed limits on rural divided highways range from 65 to 75 miles per hour (105 to 121 km/h), with some portions as high as 80 miles per hour (130 km/h). One privately run toll road in Texas, SH 130, has

4108-438: The first) example of a dual carriageway was the Via Portuensis , built in the first century by the Roman emperor Claudius between Rome and its harbor of Portus . The route between the city and the port experienced a great deal of commercial and pedestrian traffic, as Portus served as the primary avenue for the grain shipments of the Cura Annonae into Rome, as well as transporting the majority of goods imported from across

4187-485: The four parkways in what is known as the Belt System : the Shore Parkway , the Southern Parkway (not to be confused with the Southern State Parkway ), and the Laurelton Parkway . The three parkways in the Belt Parkway are a combined 25.29 miles (40.70 km) in length. The Cross Island Parkway makes up the fourth parkway in the system, but is signed separately. The Shore Parkway, Southern Parkway, Laurelton Parkway, and Cross Island Parkway are collectively known as

4266-619: The generic speed limit is 120 km/h (75 mph), minimum speed is 60 km/h (37 mph), driving backwards is strictly prohibited, and they shall not have at-grade junctions. Dual carriageways or expressways in Croatia (Croatian: brza cesta ) are non- tolled roads with 2 or more lanes in each direction, but without emergency lanes . The main motorways in Croatia are also dual carriageways, but they have emergency lanes and tolls. Many bypasses and beltways of smaller cities in Croatia have been recently constructed or planned as dual carriageways. All dual carriageways in Croatia house

4345-429: The hard shoulders. A controlled-access highway (motorway) in Spain is referred to as autopista (literally autotrack ). They may be operated by private companies and be tolled. The two major accesses to Spain from France, AP-7 into Catalonia and AP-8 into the Basque Country , are autopistas. In comparison, the prime road between Spain and Portugal is the photographed autovía A-5 . In both autopistas and autovías,

4424-478: The highest speed limit in the United States at 85 miles per hour (137 km/h). Urban divided highways which are at grade and typically have much lower speed limits are sometimes called boulevards . In keeping with the U.S. Department of Transportation 's Manual on Uniform Traffic Control Devices (MUTCD), since the early 1970s all divided highways are striped by color to show the direction of traffic flow. Two-way undivided roads have an amber center line, with

4503-539: The introduction the Irish Planning system in 1964. Today Irish planning policy prohibits such development on National Primary or National Secondary roads where the speed limit exceeds 60 km/h (37 mph). This policy results from concerns expressed by the National Roads Authority. A local authority is not obliged to implement this policy and can disregard this policy at its own discretion. This would usually only occur in exceptional circumstances or where planners are overruled by elected councillors using section 140 of

4582-655: The lanes of an existing road (for example US Highway 33 between Elkhart and Goshen in northern Indiana). Like other countries, there are several types of divided highways; fully controlled-access divided routes with interchanges (commonly known as "freeways" in the United States, Australia, and regionally within Canada), expressways that often include a mix of interchanges and traffic signals, and divided arterial roads that are almost entirely stop-controlled. Unlike some other countries, divided dual carriageways in Canada are seldom equipped with traffic circles , roundabouts, or rotaries as alternatives to stoplights. In Canada,

4661-535: The median-side baseline is solid amber, and the right sideline is solid white. Frequently in the U.S. the two carriageways are separated by some distance (wide medians with small forests or even hills in them), but drivers can always tell whether the roadway is two-way or one-way—and, if one-way, the direction in which the traffic flows—by looking at the striping coloration. For an example, see inset showing U.S. Route 52 near Lafayette, Indiana . Some divided highways have been turned into undivided highways by widening

4740-499: The namesake Neptune Avenue, the parkway enters Sheepshead Bay and connections to Coney Island . At exit 8, the Belt Parkway connects to Coney Island Avenue , approaching the namesake bay as it continues east. Paralleling Emmons Avenue through Sheepshead Bay, the parkway passes exit 9A eastbound, which connects to Knapp Street and exit 9B, which is a ramp to the eastern end of Emmons Avenue. Westbound, exit 9 services Knapp Street. Crossing south of Gerritsen Beach ,

4819-678: The need to preserve access to adjoining property or to the absence of a non-motorway alternative route. Also, dual carriageways that are not motorway classified do not need to be equipped with emergency phones. Motorway restrictions only apply to motorway sections, rather than all dual carriageway sections of national roads (these are signposted with the N prefix on the route number, rather than M ). Some national secondary roads , and regional roads in particular often have houses, schools and other developments fronting on to them. Less important national primary roads , and older sections not yet upgraded may also feature such developments built before

4898-467: The number of junctions on the dual carriageway; often other roads will pass over or under the dual carriageway without an intersection. A dual carriageway with grade-separated junctions and which meets other requirements may be upgraded to motorway standard, denoted by an (M) added after the road number (e.g. " A1(M) " or " A38(M) "). Unlike in Ireland, there was no official terminology for 'high-quality dual carriageways' until April 2015, when in England

4977-491: The official "Belt Parkway". It is designated an east–west route, and its exit numbering system begins, in standard fashion, at the western terminus of the Shore Parkway, the westernmost parkway in the system. The numbering increases as the parkway proceeds eastward, and continues onto the Cross Island at the eastern terminus of the Belt Parkway. The north–south parkway retains the numbering scheme to its northern terminus. The Belt Parkway begins at an interchange (exit 22) with

5056-399: The original system were converted to expressways , which could be used by commercial traffic. The Gowanus Expressway replaced the Gowanus Parkway in 1950 and became part of the Interstate Highway System as I-278. The Whitestone Parkway was expanded into the Whitestone Expressway starting in 1957; it also became an Interstate Highway and is signed as part of I-678 . In the late 1940s,

5135-421: The park, the Belt begins to parallel Cropsey Avenue and passes another parking area before reaching exit 5, a junction with Bay Parkway . This marks the eastern end of Dyker Beach Park, and the route begins to parallel shoreline strip malls before reaching Calvert Vaux Park . Now in the Gravesend section of Brooklyn, the Belt passes exit 6, which connects to Cropsey Avenue. Westbound, this junction

5214-419: The parkway passes south of the Plum Beach Channel and passes a small rest area on the eastbound lanes. Turning northeast through the Floyd Bennett Field area, the parkway bends north and passes a service area with gas services in the median. Just north of the service area, the Belt passes exit 11N–S, a cloverleaf interchange which connects to Flatbush Avenue and the Rockaways . After exit 11N,

5293-407: The parkway was removed in 1972. In the 1980s, the viaduct carrying traffic over the Coney Island Yard was reconstructed. In September 2002, Exit 15 was opened to serve the nearby Gateway Center commercial development. in 2005, a project to reconstruct Exit 17 was competed. The old cloverleaf interchange was demolished, and a new Dimond interchange with wider deacceleration lanes and gentler turns

5372-422: The parkway was widened in its entirety. In 1969, the New York City Council co-named the Belt Parkway Leif Ericson Drive between exit 2 and exit 9, to recognize the large Scandinavian population in Bay Ridge. By 1970, signage on much of the parkway's length (except for the Cross Island Parkway section) had been replaced by signs reading "Belt Parkway". The segment of NY 27A that ran concurrently with

5451-453: The quality of intersecting junctions. The national speed limit applies on dual carriageways (unless it is in a ' built-up area ', or a lower limit is posted), which is as follows: A dual carriageway in a built up area will have a statutory speed limit of 30 mph (48 km/h) unless otherwise sign-posted. It is common for such urban dual carriageways to have an increased speed limit of 40 mph (64 km/h). A road deemed to be in

5530-454: The roads allow higher speed traffic than is common on other roads. This in turn requires them to have dual carriageways in most cases. An exception is the 2+1 road system in some rural areas; these roads are also referred to as expressways. Autobahnähnliche Straßen mostly are colloquially referred to as gelbe Autobahn (yellow motorway) because they have the same technical standard as the Autobahn but have black on yellow signs instead of

5609-403: The same class of road, except in cities and built-up areas where the dual carriageway is more of a safety measure. When first constructed, many dual carriageways—including the first motorways—had no crash- or other barriers in the central reservation. In the event of congestion, or if a driver missed their exit, some drivers made U-turns onto the opposite carriageway; many accidents were caused as

5688-587: The shore of the Upper New York Bay . The eastbound lanes of the Belt Parkway pass several small parking areas that serve as viewing spots for the bay. Connections across the parkway to Bay Ridge are also present at these parking areas. Beginning the bend to the southeast, the parkway passes Andrew Lehman Field . Just east of the field, the Belt Parkway comes within the shadows of the Verrazzano-Narrows Bridge and passes exit 2, which serves as

5767-547: The southern end of Rockaway Parkway . Crossing over another bridge over Spring Creek, the parkway passes exit 14, which connects to Pennsylvania Avenue in Starrett City . The interchange is adjacent to the former Pennsylvania Avenue Landfill . After crossing another waterway, Hendrix Creek, the Belt passes the former Fountain Avenue Landfill and passes exit 15, a diamond interchange with Erskine Street leading to

5846-503: The southern terminus of Fourth Avenue . After crossing under the bridge, the westbound lanes enter exit 3 which connects to the Verrazzano. Eastbound, the lanes from the bridge connecting to the Belt merge in, as the road enters Dyker Beach Park and Golf Course . During a short gap away from the shore, the Belt passes a parking area for Dyker Beach Park, entering exit 4, which services Bay 8th Street and 14th Avenue. Continuing along

5925-646: The term "divided highway" is used for this type of road, and the segment between the roadways is referred to as a "median". There may be gaps in the median strip of a partially controlled-access road to allow turning and crossing. More informally, a divided highway may be referred to as "twinned". This stems from the practice of "twinning" an existing two-lane highway and converting it into a divided highway. Such highways in southern Ontario, southern Quebec, and parts of Atlantic Canada usually feature full controlled-access with interchanges where robust federal and provincial funding has made such freeways possible. However, due to

6004-551: The time, the Belt project was referred to as the "Marginal Boulevard". The Belt system was part of a "Metropolitan Loop" running through all five boroughs of New York City as well as New Jersey , proposed by the Regional Plan Association in 1929. Other highways proposed in this loop included the future Cross Bronx Expressway and Staten Island Expressway . In a 1937 report titled "New Parkways in New York City",

6083-414: The white on blue signs used on the Autobahn motorway network. These are generally high-speed arterial roads in larger cities or important roads within a federal state that do not connect to major cities, so that they do not fall under the federal budget for the Autobahn network. The federal road Bundesstraße 27 is an example where about half of its length is upgraded to a high speed motorway standard. On

6162-567: Was constructed in its place. In October 2009, NYCDOT launched the first phase of a capital project to reconstruct seven obsolete bridges along the Belt Parkway. The first phase included the reconstruction of an overpass ramp from Guider Avenue, as well as the replacement of the Paerdegat Basin and Rockaway Parkway bridges, which was completed in 2012. In 2021, the Metropolitan Transportation Authority proposed widening

6241-517: Was opened running 55 km (34 mi) from Milan to Varese . It featured a broad road bed and did not feature lane dividers except near cities and through the mountains. The London end of the Great West Road became Britain's first dual carriageway when it was opened in 1925 by King George V . In 1927 the Rome bypass was opened. It ran 92 km (57 mi) bypassing Rome to the east. Almost
