TxDOT Bridges SNBI

The Bridge dataset was developed using data provided by the Bridge Inspection Database. The Bridge Inspection Database contains a record for each Bridge Structure on public roadways in Texas. This includes Bridges maintained by TxDOT, Toll Authorities, Counties, Municipalities, and other jurisdictions. Bridge Inspection data is the primary source used to update the National Bridge Inspection File (NBI) in Washington.
