68-607: A repurposed rail viaduct provides a garden promenade on top and workspace for artisans below. The garden promenade is called the Coulée verte René-Dumont while the workspaces in the arches below are the Viaduc des Arts . The project was inaugurated in 1993. Manhattan's High Line , inaugurated in 2009, also uses an elevated train line as a linear urban park . In Indonesia viaducts are used for railways in Java and also for highways such as
102-451: A width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs , such as Chicago, Birmingham, London and Manchester . These viaducts cross the large railroad yards that are needed for freight trains there, and also cross the multi-track railroad lines that are needed for heavy rail traffic. These viaducts provide grade separation and keep highway and city street traffic from having to be continually interrupted by
136-507: Is built across land rather than water, the space below the arches may be used for businesses such as car parking, vehicle repairs, light industry, bars and nightclubs. In the United Kingdom, many railway lines in urban areas have been constructed on viaducts, and so the infrastructure owner Network Rail has an extensive property portfolio in arches under viaducts. In Berlin the space under the arches of elevated subway lines ( S-Bahn )
170-596: Is derived from the Latin via meaning "road", and ducere meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts . Like the Roman aqueducts , many early viaducts comprised a series of arches of roughly equal length. The longest viaduct in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with

This steel truss vertical lift bridge and specially-built causeway connect
238-539: Is expected to carry dual carriageways with a clearance of 16.2 metres (53 ft) above the Derwent River. Viaduct A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term viaduct
272-497: Is recognised as a landmark in the area. From 2006 until 2010, the lifting segment of the Bridgewater Bridge was out of commission, due to failed maintenance. The State Government spent $ 14 million to refurbish the bridge and provide it with a further 15 years of life, until a replacement can be built. This refurbishment replaced the vandalised control house and its controls and all of the cabling to raise and lower
306-407: Is used for several different purposes, including small eateries or bars. Elevated expressways were built in major cities such as Boston ( Central Artery ), Los Angeles, San Francisco, Seoul , Tokyo and Toronto ( Gardiner Expressway ). Some were demolished because they were unappealing and divided the city. In other cases, viaducts were demolished because they were structurally unsafe, such as
340-706: The Australian Government set aside $ 100 million towards the replacement of the Bridgewater Bridge, soon after the Tasmanian Government decided to build the replacement to the south of the existing bridge. However, after years of inaction the State government has encountered some heritage issues with replacing the bridge and is to be replaced as part of the final stage of the Brighton Bypass and Midland Highway upgrade. Towards
374-655: The Bloor-Danforth subway line on the lower deck, over the steep Don River valley . Others were built to span settled areas, crossing over roads beneath—the reason for many viaducts in London. Viaducts over water make use of islands or successive arches. They are often combined with other types of bridges or tunnels to cross navigable waters as viaduct sections, while less expensive to design and build than tunnels or bridges with larger spans, typically lack sufficient horizontal and vertical clearance for large ships.

#1732782403217408-542: The Chesapeake Bay Bridge-Tunnel . The Millau Viaduct is a cable-stayed road-bridge that spans the valley of the river Tarn near Millau in southern France. It opened in 2004 and is the tallest vehicular bridge in the world, with one pier's summit at 343 metres (1,125 ft). The viaduct Danyang–Kunshan Grand Bridge in China was the longest bridge in the world as of 2011 . Where a viaduct
442-838: The East Derwent Highway , due to traffic being diverted over the Bowen and Tasman bridges. The cables, which were put in place in 1994, were supposed to have a 20-year lifespan, and as they have lasted barely over half that time. Rail services ceased using the bridge when the South Line was cut back to terminate at the Brighton Transport Hub in June 2014. The bridge received an Engineering Heritage Marker from Engineers Australia as part of its Engineering Heritage Recognition Program . Between 2001 and 2005,
476-645: The Embarcadero Freeway in San Francisco, which was damaged by an earthquake in 1989. However, in developing nations such as Thailand ( Bang Na Expressway , the world's longest road bridge ), India ( Delhi-Gurgaon Expressway ), China, Bangladesh, Pakistan, and Nicaragua, elevated expressways have been built and more are under construction to improve traffic flow, particularly as a workaround of land shortage when built atop surface roads. Other uses have been found for some viaducts. In Paris, France,
510-608: The Southern Hemisphere , and is the largest of its kind remaining in Australia. The bridge was designed to last a century without replacement. A small control house stands on the lifting section. Inside are the switches and locks which operate the bridge. Until 1984, the Australian Newsprint Mills at Boyer moved all its produce by river. Barges were used to transport paper from the mill to
544-512: The interior of Tasmania . Construction commenced on the bridge in 1829. Operations were supervised by Roderic O'Connor . The causeway, which was constructed first, was built by a workforce of 200 convicts who had been sentenced to secondary punishment. These convicts, using nothing but wheelbarrows, shovels and picks and muscle power, shifted 2 million tonnes (2.2 million short tons) of soil, stones and clay. The finished causeway stretched 1.3 kilometres (1 mi), although did not span
578-525: The Australian Government announced a $ 461 million grant towards the construction of a new Bridgewater Bridge, representing 80 per cent of the expected total construction cost. The Tasmanian Government is expected to contribute $ 115 million. Construction was expected to commence in 2019; however, following independent assessment of the project by Infrastructure Australia in July 2019,
612-585: The Hobart suburbs of Bridgewater and Granton . The bridge was completed in 1946 and accommodates a two-lane highway , a single track railway and a grade-separated footpath . The bridge serves as a major connector link between the Midland Highway on the eastern shore and the Brooker Highway on the western shore. The bridge is the oldest surviving lift span bridge in Australia; lifting of
646-565: The bridge can cause considerable traffic delays. The Bridgewater Bridge was among the first bridges constructed in Tasmania after British settlement in 1803, and gave its name to the nearby suburb of Bridgewater. Lieutenant-Governor George Arthur commissioned the construction of the bridge and causeway to connect the Launceston – Hobart Trunk Road, linking both Tasmanian towns and providing easier access to farmlands in
680-403: The bridge was closed, so the bridge was modified again to solve this problem. The bridge lasted several decades more before being replaced by two swing bridges in the early 1900s, one for the railway, and one for the road traffic. The pivot and the sandstone abutments of the railway bridge are still standing and can be viewed on the left of the present bridge as one travels towards the north. Both
714-507: The bridge. Touted as a "major tourist attraction" with expected regular openings for tourist and private vessels to travel between Hobart and New Norfolk , the bridge refurbishment has been a major embarrassment to the Tasmanian Government. It has opened no more than six times successfully and has caused major traffic delays, including on a well-promoted occasion the lift span raised approximately 14 centimetres (5.5 in) and

#1732782403217748-419: The end of 2010, the State government released plans for a new Derwent River crossing, next to the current bridge. The new bridge, when complete, will carry the Midland Highway and the old bridge will be left open for rail, pedestrian and local traffic. While the Bridgewater Bridge is recognised as being limited in its ability to perform the function of the Midland Highway, it also has important heritage values and
782-447: The evaluation identified a range of issues, which may add to costs and require further work to address, and recommended that the Tasmanian Government revise its business case. The project is scheduled to start design and approvals in 2019, with the design to be agreed by the end of 2020. Substantive construction is expected to commence in 2022 and completion is targeted in 2024. The 1.6-kilometre-long (1 mi) concrete box girder bridge
816-481: The first and second swing bridges did not run straight off the end of the causeway; rather, they turned slightly to the right. The second swing bridge was left standing when the present lifting bridge was being constructed to prevent traffic stoppages, so the present bridge deviates from the causeway quite appreciably. Construction on the present steel vertical lift bridge across the Derwent began in 1939. Construction
850-425: The full width of the Derwent. The original plan apparently called for a viaduct , but this plan was abandoned and the half-built arches were filled in to form the present causeway. Upon completion of the causeway, a punt operated across the deep, navigable section of the river, but could not cope with traffic demands. To resolve this issue, the first bridge across this point of the Derwent opened in 1849. The bridge
884-417: The house which contains the bridge operating controls, closed-circuit television cameras were installed along the lifting span sometime between 2003 and 2005. On 30 October 2006 a fault was found in one of the steel cables holding up the two 170-tonne (190-short-ton) concrete counterweights above the road, forcing the temporary closure of the bridge. This closure caused peak hour traffic delays, mainly along
918-419: The north was passing over the bridge when the engine left the tracks and tipped over, hanging precariously above the water on the edge of the southern end of the swing bridge. Two people, fireman William Shaw and passenger Daniel Turner, died as a result of the accident. The driver was injured. The locomotive was salvageable. The cause of the accident was found to be that the rails failed to match properly when

986-431: The storage sheds at Pavilion Point at Hobart, and for this reason the bridge was required to open very frequently. Consequently, a bridge-keeper lived on-site and opened and closed the bridge when required. However, when the decision was made to cease river transportation, an on-site keeper was no longer necessary, so although the bridge can and does still open, bridge openings are now infrequent. In response to vandalism of
1020-564: The traffic load, necessitating a viaduct for "through" traffic. Such bridges also lend themselves for use by rail traffic, which requires straighter and flatter routes. Some viaducts have more than one deck, such that one deck has vehicular traffic and another deck carries rail traffic. One example of this is the Prince Edward Viaduct in Toronto, Canada, that carries motor traffic on the top deck as Bloor Street , and metro as
1054-445: The train traffic. Likewise, some viaducts carry railroads over large valleys, or they carry railroads over cities with many cross-streets and avenues. Many viaducts over land connect points of similar height in a landscape, usually by bridging a river valley or other eroded opening in an otherwise flat area. Often such valleys had roads descending either side (with a small bridge over the river, where necessary) that become inadequate for

1088-490: Was designed by the firm of architect and former convict James Blackburn . Being a sliding bridge , it could slide back to allow shipping to pass through. In the late 1870s, the Tasmanian Main Line Railway called for modifications to the causeway so they could lay tracks over it. The causeway required widening and the sliding bridge was now replaced by a swing bridge. On 22 July 1886, a train from
1122-464: Was interrupted by World War II ; the bridge opened to road traffic in March 1942, with completion of the lifting segment finally completed in early 1946. The bridge opened to rail traffic in late 1946. It consists of a long concrete bridge that leads off the end of the causeway, and a steel lifting section just before the northern bank of the river. The lifting section is one of only a few remaining in
1156-417: Was stuck in that position for several minutes before being lowered again. In March 2016, Infrastructure Tasmania published its review of a design and cost estimate for the construction of a replacement structure for the existing Bridgewater Bridge, which considered various options for a replacement structure and provided advice as to the most feasible crossing solution. As part of the 2018-19 federal budget ,
