A diagram showing how scour holes are formed. Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Hydrodynamic scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure.
Road bridge Bridge scour caused by jack posts installed 4 days earlier caused instability and led to the partial collapse of the northern arch 0 dead, 0 injured (the bridge was closed to traffic at the time) Partial collapse (northern arch) Fully demolished in July 2020 and rebuilt.

The bridge information includes the design of the bridge and the dimensions of the usable portion. The data is often used to analyze bridges and to judge their condition. The inventory is developed for the purpose of having a unified database for bridges to ensure the safety of the traveling public, as required by the Federal Aid Highway Act of ...

Examples of this hydrological process can be found globally. [2] [better source needed] [3] [4] Two locations in the United States where tidal scour is the predominant shaping force is the San Francisco Bay and the Elkhorn Slough.
