This is known as "clearance below", "vertical clearance" and "charted height" [3] [24] [25] On other hand, the "overhead clearance" is a measurement from the top most part of a given vessel to the underside of the bridge. The "underkeel clearance" is the distance between the lowest part of a given vessel to the waterway bed. [25] The other type ...
This bridge spans a deep river gorge. The bridge's two towers, built on the rims of the gorge, are 269 m (883 ft) tall, but due to the depth of the river gorge between the towers, the deck height of the Duge Bridge is 565 m (1,854 ft). The Millau Viaduct is a cable-stayed bridge that is both tall (in structural height) and high (in deck height ...
The code also defines the clearance that is shorter than the physical clearance to account for sag curves, bridge deflection and expected settlements with a recommendation of minimum clearance of 5 metres (16 ft 5 in). [2] In UK, the "standard minimum clearance" for structures over public highways is 16 feet 6 inches (5.03 m). [3]
This list of tallest bridges includes bridges with a structural height of at least 200 metres (660 ft). The structural height of a bridge is the maximum vertical distance from the uppermost part of a bridge, such as the top of a bridge tower, to the lowermost exposed part of the bridge, where its piers, towers, or mast pylons emerge from the surface of the ground or water.
The bridge is a combined road and railway vertical-lift bridge. It carries a 24-foot (7.3m) wide two-lane road, a 6-foot (1.8m) wide footpath and a single-track electrified railway line. Although the railway operates by electrified third rail , there is no electrification over the moving section of the bridge.
The bridge deck is suspended by 162 vertical wrought-iron rods in 81 matching pairs. The Clifton Bridge Company initially managed the bridge under licence from a charitable trust. The trust subsequently purchased the company shares, completing this in 1949 and took over the running of the bridge using the income from tolls to pay for maintenance.
The Tyne Bridge is a through arch bridge over the River Tyne in North East England, linking Newcastle upon Tyne and Gateshead.
