2007 Bridge Inventory

FHWA, in consultation with the states, has assigned a sufficiency rating SR to each bridge (20 ft. or more) inventoried. Formula SR rating factors are as outlined in the current Recording and Coding Guide for Structures Inventory and Appraisal SI&A of the Nations Bridges.

Our thanks to all the state highway engineers for their continuing cooperation and special effort to provide current data through September 2007.
