Abstract

Bridge strikes—events where over-height vehicles impact bridge superstructures—are common across the United States and pose significant challenges for bridge owners. When a bridge strike occurs, bridge owners must assess the damage and determine what, if any, action is required. A survey of state highway agencies was conducted, and 23 responses were received. States reported general metrics about low-clearance bridges and bridge strikes, and data from the National Bridge Inventory were analyzed to provide additional insight. States also reported information about inspection, analysis, and repair practices for damaged girders. Overall, reported practices vary greatly between states and rely significantly on engineering judgement; there is potential to improve efficiency and efficacy. Results can be used to inform future research directions regarding steel girders damaged in bridge strikes, such as innovative methods for damage inspection, assessment, and repair.
