The Beesley's Point Bridge was a bridge in New Jersey , United States, that was built privately by the Ocean City Automobile Club in 1927. Completed in 1928, control of the bridge was acquired by the Beesley's Point Bridge Company. It was a toll bridge from its opening. Prior to its closing, it was best known for carrying U.S. Route 9 (US 9) over the Great Egg Harbor Bay , connecting Upper Township , in Cape May County to Somers Point in Atlantic County . Route 9 and the Garden State Parkway temporally concurred over the Beesley's Point Bridge from the Parkway's opening in 1954 until a separate bridge over the bay for the Parkway, the Great Egg Harbor Bridge , opened in 1955.
69-745: The Great Egg Harbor Bridge is a series of four bridges along the Garden State Parkway in New Jersey , with tolls collected in the southbound direction. It crosses the Great Egg Harbor Bay , connecting Upper Township , in Cape May County to Somers Point in Atlantic County . The bridge crosses over a section of Egg Harbor Township , and Drag Island. It has carried a portion of U.S. Route 9 since 2013. The Garden State Parkway
138-596: A bridge-restaurant which is a bridge built to serve as a restaurant. Other suspension bridge towers carry transmission antennas. Conservationists use wildlife overpasses to reduce habitat fragmentation and animal-vehicle collisions. The first animal bridges sprung up in France in the 1950s, and these types of bridges are now used worldwide to protect both large and small wildlife. Bridges are subject to unplanned uses as well. The areas underneath some bridges have become makeshift shelters and homes to homeless people, and
207-520: A bridge is to be designed, standards authorities specify simplified notional load models, notably HL-93, intended to give the same load effects as the characteristic maximum values. The Eurocode is an example of a standard for bridge traffic loading that was developed in this way. Most bridge standards are only applicable for short and medium spans - for example, the Eurocode is only applicable for loaded lengths up to 200 m. Longer spans are dealt with on
276-471: A case-by-case basis. It is generally accepted that the intensity of load reduces as span increases because the probability of many trucks being closely spaced and extremely heavy reduces as the number of trucks involved increases. It is also generally assumed that short spans are governed by a small number of trucks traveling at high speed, with an allowance for dynamics. Longer spans on the other hand, are governed by congested traffic and no allowance for dynamics
345-561: A causeway, and form a part of the Garden State Parkway. In construction, the bridge project utilized 140 prestressed concrete beams, each 40 feet (12 m) in length, at an individual cost of $ 640 (equivalent to $ 7,261 in 2023). The project also used a concrete deck at the cost of less than $ 2 per square foot . On May 26, 1956, the Great Egg Harbor Bridge opened at a cost of US$ 4.5 million , completing
414-549: A causeway. A small portion of the bridge enters Egg Harbor Township . Another bridge crosses Drag Channel to the mainland of Atlantic County in Somers Point. As with the rest of the Garden State Parkway, the bridge is a component of the National Highway System , a network of roadways that are important to the country's economy, defense, and mobility. The bridge carries two lanes of traffic in each direction. The bridge
483-480: A combination of structural health monitoring and testing. This is regulated in country-specific engineer standards and includes an ongoing monitoring every three to six months, a simple test or inspection every two to three years and a major inspection every six to ten years. In Europe, the cost of maintenance is considerable and is higher in some countries than spending on new bridges. The lifetime of welded steel bridges can be significantly extended by aftertreatment of
552-399: A different site, and re-used. They are important in military engineering and are also used to carry traffic while an old bridge is being rebuilt. Movable bridges are designed to move out of the way of boats or other kinds of traffic, which would otherwise be too tall to fit. These are generally electrically powered. The Tank bridge transporter (TBT) has the same cross-country performance as
621-594: A few will predominate. The separation of forces and moments may be quite clear. In a suspension or cable-stayed bridge , the elements in tension are distinct in shape and placement. In other cases the forces may be distributed among a large number of members, as in a truss. The world's longest beam bridge is Lake Pontchartrain Causeway in southern Louisiana in the United States, at 23.83 miles (38.35 km), with individual spans of 56 feet (17 m). Beam bridges are
690-564: A form of boardwalk across marshes ; examples of such bridges include the Sweet Track and the Post Track in England, approximately 6000 years old. Ancient people would also have used log bridges consisting of logs that fell naturally or were intentionally felled or placed across streams. Some of the first human-made bridges with significant span were probably intentionally felled trees. Among

Included in the project was demolishing the Beesley's Point Bridge , built in 1928, and closed to traffic in June 2004 due to damage. On September 20, 2012, the NJTA held a public meeting in Upper Township about the proposed bridge. In March 2013, the NJTA awarded Route 52 Constructors a $ 129.8 million (2013 USD) contract to build
897-453: A project that also replaced the Great Egg Harbor Bridge. On September 7, 2016 the toll bridge section caught fire. The last section of the bridge was demolished on November 18, 2016. The bridge carried two lanes of traffic for approximately 4,800 feet (1,500 m). The structure immediately north over the Drag Channel was a separate structure and is commonly referred to incorrectly as
966-556: A proper evacuation route, the New Jersey Turnpike Authority (NJTA) proposed a replacement bridge as early as 2010. The NJTA worked with the United States Coast Guard as the lead federal agency for the project due to the crossing over a navigable roadway. The proposed project would construct a new southbound bridge, wide enough to carry traffic in both directions in the event of an emergency, as well as carrying
1035-578: A span of 552 m (1,811 ft). The bridge was opened 29 April 2009, in Chongqing , China. The longest suspension bridge in the world is the 4,608 m (15,118 ft) 1915 Çanakkale Bridge in Turkey. The longest cable-stayed bridge since 2012 is the 1,104 m (3,622 ft) Russky Bridge in Vladivostok , Russia. Some Engineers sub-divide 'beam' bridges into slab, beam-and-slab and box girder on
1104-732: A stream. Often in palaces, a bridge will be built over an artificial waterway as symbolic of a passage to an important place or state of mind. A set of five bridges cross a sinuous waterway in an important courtyard of the Forbidden City in Beijing, China. The central bridge was reserved exclusively for the use of the Emperor and Empress, with their attendants. The estimated life of bridges varies between 25 and 80 years depending on location and material. Bridges may age hundred years with proper maintenance and rehabilitation. Bridge maintenance consisting of

Upper Township in Cape May County connects with Somers Point via the Great Egg Harbor Bridge on the Parkway. This bridge first crosses over Harbor Road, which is the last street in Beesley's Point , connecting homes along Great Egg Harbor Bay and Peck Bay to U.S. Route 9 . The bridge then crosses Great Egg Harbor Bay to Drag Island, which it crosses as
1311-456: Is a bridge that carries water, resembling a viaduct, which is a bridge that connects points of equal height. A road-rail bridge carries both road and rail traffic. Overway is a term for a bridge that separates incompatible intersecting traffic, especially road and rail. Some bridges accommodate other purposes, such as the tower of Nový Most Bridge in Bratislava , which features a restaurant, or
1380-462: Is also historically significant as it is the world's oldest open-spandrel stone segmental arch bridge. European segmental arch bridges date back to at least the Alconétar Bridge (approximately 2nd century AD), while the enormous Roman era Trajan's Bridge (105 AD) featured open-spandrel segmental arches in wooden construction. Rope bridges , a simple type of suspension bridge , were used by
1449-574: Is an early example of a double-decked bridge. The upper level carries a railway, and the lower level is used for road traffic. Other examples include Britannia Bridge over the Menai Strait and Craigavon Bridge in Derry, Northern Ireland. The Oresund Bridge between Copenhagen and Malmö consists of a four-lane highway on the upper level and a pair of railway tracks at the lower level. Tower Bridge in London

A viaduct is made up of multiple bridges connected into one longer structure. The longest and some of the highest bridges are viaducts, such as the Lake Pontchartrain Causeway and Millau Viaduct . A multi-way bridge has three or more separate spans which meet near
1587-417: Is led by architects, bridges are usually designed by engineers. This follows from the importance of the engineering requirements; namely spanning the obstacle and having the durability to survive, with minimal maintenance, in an aggressive outdoor environment. Bridges are first analysed; the bending moment and shear force distributions are calculated due to the applied loads. For this, the finite element method
1656-540: Is needed. Calculating the loading due to congested traffic remains a challenge as there is a paucity of data on inter-vehicle gaps, both within-lane and inter-lane, in congested conditions. Weigh-in-Motion (WIM) systems provide data on inter-vehicle gaps but only operate well in free flowing traffic conditions. Some authors have used cameras to measure gaps and vehicle lengths in jammed situations and have inferred weights from lengths using WIM data. Others have used microsimulation to generate typical clusters of vehicles on
1725-737: Is the most popular. The analysis can be one-, two-, or three-dimensional. For the majority of bridges, a two-dimensional plate model (often with stiffening beams) is sufficient or an upstand finite element model. On completion of the analysis, the bridge is designed to resist the applied bending moments and shear forces, section sizes are selected with sufficient capacity to resist the stresses. Many bridges are made of prestressed concrete which has good durability properties, either by pre-tensioning of beams prior to installation or post-tensioning on site. In most countries, bridges, like other structures, are designed according to Load and Resistance Factor Design (LRFD) principles. In simple terms, this means that
1794-614: Is used heavily in the summertime, peaking on Saturdays. In 1952, the New Jersey Highway Authority (NJHA) was created to facilitate the construction of the Garden State Parkway. In October 1954, the NJHA received bids for constructing a 3,650-foot (1,110 m) bridge crossing the Great Egg Harbor Bay, beginning at Beesley's Point, as well as a 750-foot (230 m) bridge crossing Drag Channel. The bridges would be linked by

Likewise, in Toronto , the Prince Edward Viaduct has five lanes of motor traffic, bicycle lanes, and sidewalks on its upper deck; and a pair of tracks for the Bloor–Danforth subway line on its lower deck. The western span of the San Francisco–Oakland Bay Bridge also has two levels. Robert Stephenson 's High Level Bridge across the River Tyne in Newcastle upon Tyne , completed in 1849,
2070-596: The ancient Romans . The Romans built arch bridges and aqueducts that could stand in conditions that would damage or destroy earlier designs, some of which still stand today. An example is the Alcántara Bridge , built over the river Tagus , in Spain. The Romans also used cement, which reduced the variation of strength found in natural stone. One type of cement, called pozzolana , consisted of water, lime , sand, and volcanic rock . Brick and mortar bridges were built after
2139-495: The river Severn . With the Industrial Revolution in the 19th century, truss systems of wrought iron were developed for larger bridges, but iron does not have the tensile strength to support large loads. With the advent of steel, which has a high tensile strength, much larger bridges were built, many using the ideas of Gustave Eiffel . In Canada and the United States, numerous timber covered bridges were built in

2208-511: The 18th century, there were many innovations in the design of timber bridges by Hans Ulrich Grubenmann , Johannes Grubenmann , as well as others. The first book on bridge engineering was written by Hubert Gautier in 1716. A major breakthrough in bridge technology came with the erection of the Iron Bridge in Shropshire, England in 1779. It used cast iron for the first time as arches to cross
2277-434: The Garden State Parkway. The bridge carried traffic in both directions, but soon was unable to accommodate the increasing traffic. A parallel bridge carrying northbound traffic was opened in 1972. In 1999, the northbound span was closed for seven weeks after cracks were found in the steel hangars. In 2000, after cracking was found in the steel supports on the southbound bridge, construction crews made emergency repairs at
2346-544: The Great Egg Harbor Bay. In 2006, Hurricane Ernesto made Cape May County officials nervous because they lacked the use of the bridge as an additional evacuation route. As a result, Cape May County purchased the bridge from the Beesley's Point Bridge Company for $ 1 with the intent of rehabilitating it and opening it in 2012. Several studies were commissioned regarding the feasibility of doing so, but Cape May County engineers concluded that significant rehabilitation would extend

2484-610: The appearance of the bridge can have great importance. Often, this is the case with a large bridge that serves as an entrance to a city, or crosses over a main harbor entrance. These are sometimes known as signature bridges. Designers of bridges in parks and along parkways often place more importance on aesthetics, as well. Examples include the stone-faced bridges along the Taconic State Parkway in New York. Bridges are typically more aesthetically pleasing if they are simple in shape,
2553-613: The attention of the general public in the 1990s by the novel, movie and play The Bridges of Madison County . In 1927, welding pioneer Stefan Bryła designed the first welded road bridge in the world, the Maurzyce Bridge which was later built across the river Słudwia at Maurzyce near Łowicz , Poland in 1929. In 1995, the American Welding Society presented the Historic Welded Structure Award for

A slab can be solid or voided (though this is no longer favored for inspectability reasons) while beam-and-slab consists of concrete or steel girders connected by a concrete slab. A box-girder cross-section consists of a single-cell or multi-cellular box. In recent years, integral bridge construction has also become popular. Most bridges are fixed bridges, meaning they have no moving parts and stay in one place until they fail or are demolished. Temporary bridges, such as Bailey bridges , are designed to be assembled, taken apart, transported to

As a result, the Company agreed to close the bridge and it closed to traffic on June 18, 2004. After the bridge closed, US 9 was not rerouted, and as such was rendered incomplete. This remained unchanged until 2013, when the permanent US 9
2829-437: The bridge to Poland. Bridges can be categorized in several different ways. Common categories include the type of structural elements used, by what they carry, whether they are fixed or movable, and by the materials used. Bridges may be classified by how the actions of tension , compression , bending , torsion and shear are distributed through their structure. Most bridges will employ all of these to some degree, but only

2898-494: The bridge would reopen to traffic in 2012. On June 28, 2010 a Press of Atlantic City article revealed that a previous crack in the existing deck had turned into a three-foot chasm. At the 7th Annual Cape May County Transportation Infrastructure Conference on February 22, 2011, it was announced that the bridge would be demolished but discussions were in the preliminary mode. Demolition of the bridge began in July 2013 in conjunction with
2967-451: The bridge's life by no more than 15 years. Estimates of the price of rehabilitation varied, but it appeared that a lifespan of just 15 years on the investment would not be worth the cost. The NJDOT planned to fund a project to rehabilitate the bridge to last at least to 2019 in their Statewide Transportation Program 2011-2019. Cape May County officials, including Jeff Van Drew , stated that bridge rehabilitation would begin in mid-2010 and

In 1997, the bridge company, in conjunction with private outside investors, secured a $ 1 million loan from the New Jersey Department of Transportation to fund the necessary improvements in exchange for a promise that they would continue to keep
3105-439: The center of the bridge. Multi-way bridges with only three spans appear as a "T" or "Y" when viewed from above. Multi-way bridges are extremely rare. The Tridge , Margaret Bridge , and Zanesville Y-Bridge are examples. A bridge can be categorized by what it is designed to carry, such as trains, pedestrian or road traffic ( road bridge ), a pipeline ( Pipe bridge ) or waterway for water transport or barge traffic. An aqueduct
3174-511: The cost of $ 900,000 (equivalent to about $ 1,592,000 in 2023). A 2002 study by the NJDOT Bridge Management System indicated that both the northbound and southbound bridges over Great Egg Harbor were structurally deficient , and the crossing of Drag Channel was functionally obsolete . A traffic study in 2004 identified poor pavement on the bridge. To address the structural deficiency along substandard roadway, and to maintain
3243-445: The current southbound bridge so that the northbound bridge could undergo repairs. In July 2016, the NJTA awarded a $ 49.8 million contract to rehabilitate the northbound span and demolish the old southbound bridge. The road project was completed in May 2019. After the current south bridge was finished, Southbound traffic was then redirected to the current southbound bridge, at which point
3312-467: The deck is thinner in proportion to its span, the lines of the structure are continuous, and the shapes of the structural elements reflect the forces acting on them. To create a beautiful image, some bridges are built much taller than necessary. This type, often found in east-Asian style gardens, is called a Moon bridge , evoking a rising full moon. Other garden bridges may cross only a dry bed of stream-washed pebbles, intended only to convey an impression of
3381-485: The lake. Between 1358 and 1360, Rudolf IV, Duke of Austria , built a 'new' wooden bridge across the lake that was used until 1878; it was approximately 1,450 metres (4,760 ft) long and 4 metres (13 ft) wide. On 6 April 2001, a reconstruction of the original wooden footbridge was opened; it is also the longest wooden bridge in Switzerland. The Arkadiko Bridge is one of four Mycenaean corbel arch bridges part of

After the current south bridge was finished, Southbound traffic was then redirected to the current southbound bridge, at which point the original was demolished. Traffic was available on both the north bound and southbound bridges for a small amount of time, after which northbound traffic was redirected to
3519-748: The late 1700s to the late 1800s, reminiscent of earlier designs in Germany and Switzerland. Some covered bridges were also built in Asia. In later years, some were partly made of stone or metal but the trusses were usually still made of wood; in the United States, there were three styles of trusses, the Queen Post, the Burr Arch and the Town Lattice. Hundreds of these structures still stand in North America. They were brought to

#17328519168603588-427: The load is factored up by a factor greater than unity, while the resistance or capacity of the structure is factored down, by a factor less than unity. The effect of the factored load (stress, bending moment) should be less than the factored resistance to that effect. Both of these factors allow for uncertainty and are greater when the uncertainty is greater. Most bridges are utilitarian in appearance, but in some cases,
3657-512: The new crossing. The bridge was supported by 20 piers with 3 columns each, using prestressed concrete beams. This created a wider channel than the original 1954 bridge. To test the performance of the pilings, the crew performed the first statnamic load test in the state of New Jersey. Construction crews worked to avoid disrupting migratory bird and fish species. In August 2016, the new southbound bridge opened, and in November of that year,
3726-616: The oldest timber bridges is the Holzbrücke Rapperswil-Hurden bridge that crossed upper Lake Zürich in Switzerland; prehistoric timber pilings discovered to the west of the Seedamm causeway date back to 1523 BC. The first wooden footbridge there led across Lake Zürich; it was reconstructed several times through the late 2nd century AD, when the Roman Empire built a 6-metre-wide (20 ft) wooden bridge to carry transport across

The Oxford English Dictionary also notes that there is some suggestion that the word can be traced directly back to Proto-Indo-European *bʰrēw-. However, they also note that "this poses semantic problems." The origin of the word for the card game of the same name is unknown. The simplest and earliest types of bridges were stepping stones . Neolithic people also built
3864-494: The original was demolished. Traffic was available on both the north bound and southbound bridges for a small amount of time, after which northbound traffic was redirected to the current southbound bridge so that the northbound bridge could undergo repairs. On July 8, 2020, a bike and walking path opened on the southbound span, connecting Beesley's Point with US 9 in Somers Point. The northern portion in Somers Point required bikers and walkers to navigate traffic entering and exiting
3933-629: The past, these load models were agreed by standard drafting committees of experts but today, this situation is changing. It is now possible to measure the components of bridge traffic load, to weigh trucks, using weigh-in-motion (WIM) technologies. With extensive WIM databases, it is possible to calculate the maximum expected load effect in the specified return period. This is an active area of research, addressing issues of opposing direction lanes, side-by-side (same direction) lanes, traffic growth, permit/non-permit vehicles and long-span bridges (see below). Rather than repeat this complex process every time
4002-405: The path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where

4485-740: The undertimbers of bridges all around the world are spots of prevalent graffiti. Some bridges attract people attempting suicide, and become known as suicide bridges . The materials used to build the structure are also used to categorize bridges. Until the end of the 18th century, bridges were made out of timber, stone and masonry. Modern bridges are currently built in concrete, steel, fiber reinforced polymers (FRP), stainless steel or combinations of those materials. Living bridges have been constructed of live plants such as Ficus elastica tree roots in India and wisteria vines in Japan. Unlike buildings whose design
