2002 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 Nation's Bridges."

*SD/FO = Structurally Deficient or Functionally Obsolete
