Dept. of Transportation, IG Audit of Oversight of Load Ratings and Postings on Structurally Deficient Bridges on the National Highway System, March, 21 2006 (33 pages, PDF)

  • Summary: “On March 21, we issued a final report on state transportation departments’ actions in calculating load ratings and posting weight limits on structurally deficient National Highway System bridges and FHWA’s oversight of state actions. We found that inaccurate or outdated maximum weight limit calculations and posting entries were recorded in bridge databases of the state transportation departments and in the National Bridge Inventory, and that FHWA can do more to oversee states’ actions in inspecting bridges, calculating load limits and posting maximum weight limits. FHWA concurred with our recommendations to revise its annual compliance reviews of state bridge programs and evaluate greater use of computerized bridges management systems.”
