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 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 Frederick G. Gardiner Expressway, commonly known as the Gardiner Expressway or simply the Gardiner, is a partially at grade and elevated municipal expressway in Toronto, Ontario, Canada. Running close to the shore of Lake Ontario, it extends from the foot of the Don Valley Parkway (DVP) in the east, just past the mouth of the Don River, to the junction of Highway 427 and the Queen Elizabeth Way (QEW) in the west, for a total length of 18.0 kilometres (11.2 mi). East of Dufferin Street to just east of the Don River, the roadway is elevated for a length of 6.8 kilometres (4.2 mi), unofficially making it the longest bridge in Ontario.
The Champlain Bridge was a steel truss cantilever bridge with approach viaducts constructed of prestressed concrete beams supporting a prestressed concrete deck paved with asphalt. Opened in 1962, the bridge crossed the Saint Lawrence River, connecting the Island of Montreal to its South Shore suburbs.
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end. For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
The Credit River is a river in southern Ontario, which flows from headwaters above the Niagara Escarpment near Orangeville and Caledon East to empty into Lake Ontario at Port Credit, Mississauga. It drains an area of approximately 1,000 square kilometres (390 sq mi). The total length of the river and its tributary streams is over 1,500 kilometres (930 mi).
A footbridge is a bridge designed solely for pedestrians. While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic.
A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a plank or beam such as the support structure for a trestle table. Each supporting frame is a bent. A trestle differs from a viaduct in that viaducts have towers that support much longer spans and typically have a higher elevation.
Dufferin Street is a major north–south street in Toronto, Vaughan and King, Ontario, Canada. It is a concession road, two concessions (4 km) west of Yonge Street. The street starts at Exhibition Place, continues north to Toronto's northern boundary at Steeles Avenue with some discontinuities and continues into Vaughan, where it is designated York Regional Road 53. The street is named for Frederick Hamilton-Temple-Blackwood, 1st Marquess of Dufferin and Ava, who served as Governor General of Canada from 1872 to 1878. Prior to 1878, the street was labelled as Western City Limits or Sideline Road south off Bloor. In 2003 and 2007, it was voted as one of "Ontario's Worst 20 Roads" in the Ontario's Worst Roads poll organized by the Canadian Automobile Association.
Hoggs Hollow Bridge, originally known as the Yonge Boulevard Viaduct, is a set of four separate highway bridges that span the West Branch of the Don River Valley in Toronto, Ontario, Canada, and carries 14 lanes of Highway 401. The four structures are the busiest multi-span bridge crossing in North America, surpassing the Brooklyn Bridge.
The Ryde Bridge, also called the Uhrs Point Bridge, are two road bridges that carry Concord Road, part of the A3, across Parramatta River from Ryde in the northern suburbs of Sydney to Rhodes in Sydney's inner west, in New South Wales, Australia.
The Cambie Bridge is a six-lane, precast, box girder bridge spanning False Creek in Vancouver, British Columbia. The current bridge opened in 1985, but is the third bridge at the same location. Often referred to as the Cambie Street Bridge, it connects Cambie Street on the south shore of False Creek to both Nelson and Smithe Streets in the downtown peninsula. It is the easternmost of False Creek's fixed crossings; the Burrard and Granville bridges are a little more than a kilometre to the west, and the new Canada Line SkyTrain tunnel is built just west of the Cambie Bridge.
Mahatma Gandhi Setu is a bridge over the river Ganges in Bihar, India, connecting Patna in the south to Hajipur in the north. Its length of 5,750 metres (18,860 ft) makes it the fourth-longest river bridge in India. It was inaugurated in May 1982 in a ceremony in Hajipur by then-prime minister Indira Gandhi. From 1982 to 2017, Mahatma Gandhi Setu remained the longest bridge in India. Later, the Gandhi Setu rehabilitation project was undertaken to install triangular steel trusses on Mahatma Gandhi Setu.
The Old Eastern Avenue Bridge consists of two bridges spanning the Don River in Toronto, Ontario, Canada. The north bridge or Gas Line Bridge is a concrete arch bridge built for Consumer's Gas Company and is used by Enbridge Gas to carry a major gas main. The southern Howe truss bridge, similar to Queen Street Viaduct and Sir Isaac Brock Bridge, previously carried traffic on Eastern Avenue but is currently unused.
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box.
Krymsky Bridge is a steel suspension bridge in Moscow. The bridge spans the Moskva River 1,800 metres south-west from the Kremlin and carries the Garden Ring across the river. The bridge links the Zubovsky Boulevard to the north-west with Krymsky Val street to the south-east. The nearby Moscow Metro stations are Park Kultury and Oktyabrskaya.
The Bahia Honda Rail Bridge is a derelict railroad bridge in the lower Florida Keys connecting Bahia Honda Key with Spanish Harbor Key. It was originally part of the Overseas Railway, but the state of Florida purchased it from the Florida East Coast Railway (FEC) after the 1935 Labor Day Hurricane and converted it for automobile use as part of the Overseas Highway in 1938. After a replacement Bahia Honda Bridge was opened in 1972, two spans of the old bridge were removed for the safety of boat traffic and to prevent pedestrian access to unsafe parts of the bridge.
Moses Wheeler Bridge carries Interstate 95 over the Housatonic River between Stratford and the Devon section of Milford. The current bridge is a 14-span continuous girder and floorbeam structure that carries three lanes of traffic in each direction, with full inside and outside shoulders. The current bridge, completed in 2016, replaces a pre-existing structure that was completed as part of the original Connecticut Turnpike in 1958. The original bridge was a 34-span plate girder structure with a concrete deck with three 12-foot travel lanes in each direction and no shoulders. The central span of the original bridge over the river's navigation channel included a pin and hanger assembly, which are no longer used in bridge construction in the United States. Construction on the Moses Wheeler Bridge began in 1955 and opened on January 2, 1958.
The Bellows Falls Arch Bridge was a three-hinged steel through arch bridge over the Connecticut River between Bellows Falls, Vermont and North Walpole, New Hampshire. It was structurally significant as the longest arch bridge in the United States when it was completed in 1905.
The Abetxuko Bridge is a steel girder bridge with organic forms in Vitoria-Gasteiz, Álava, Basque Country, Spain.
