This is a list of bridges and overpasses whose low clearance causes a notable amount of accidents, also known as bridge strikes. Simply being struck by a vehicle is not criteria for inclusion on this list. To be included, the bridge should have a notable history of strikes. Many countries establish minimum standards for the structure gauge of ...
The clearance below required under bridges for the largest ships—container ships, ocean liners and cruise ships—is around 220 feet (67 m) so there are often bridges with approximately that height located in coastal cities with bays or inlets, such as New York City's Verrazzano-Narrows Bridge and San Francisco's Golden Gate Bridge.
In civil engineering, clearance refers to the difference between the loading gauge and the structure gauge in the case of railroad cars or trams, or the difference between the size of any vehicle and the width/height of doors, the width/height of an overpass or the diameter of a tunnel as well as the air draft under a bridge, the width of a lock or diameter of a tunnel in the case of watercraft.
Through urban areas, at least one routing is to have 16-foot (4.9 m) clearances, but others may have a lesser clearance of 14 feet (4.3 m). Sign supports and pedestrian overpasses must be at least 17 feet (5.2 m) above the road, except on urban routes with lesser clearance, where they should be at least 1 foot (30 cm) higher than other objects.
As a result, they must be built to accommodate the clearance under the bridge. At mean high water, that clearance is 228 ft (69 m). [82] The RMS Queen Mary 2, one such vessel built to Verrazzano-Narrows Bridge specifications, was designed with a flatter funnel to pass under the bridge, and has 13 ft (3.96 m) of clearance under the bridge during ...
Park Avenue Bridge – New York City bridge with twin 340-foot (100 m) spans, which replaced a swing bridge in 1956, carrying all Metro-North lines operating out of Grand Central Terminal. PATH Lift Bridge – Carries Port Authority Trans-Hudson (PATH) tracks over Hackensack River between Kearny and Jersey City, New Jersey , built in 1900.
This list ranks the world's cable-stayed bridges by the length of main span, i.e. the distance between the suspension towers. The length of the main span is the most common way to rank cable-stayed bridges. If one bridge has a longer span than another, it does not mean that the bridge is the longer from shore to shore, or from anchorage to ...
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]
