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 bridges. For example, the United States requires a height of 14 feet (4.27 m) for highway bridges.[1] Some vehicle standards are made to conform to these expectations. In much of the United States, the maximum height of a semi truck, in the absence of an approved overheight permit, is 13 feet, 6 inches (4.12 m).[2] Some bridges were built before the adoption of these standards, and are undersized. Accidents involving these bridges have spurred mitigation efforts, such as installing sensors and signs that warn drivers.[3] These efforts do not entirely eliminate strikes, prompting some efforts to increase the clearance height.[4]
Viral videos of bridge strikes have generated substantial public interest.[5][6] One of the most famous examples of this is the Norfolk Southern–Gregson Street Overpass, also known as the "11foot8" bridge, which was popularized by a YouTube channel.[7]
