SAVE OUR BRIDGES

THE METHODOLOGY

There are nearly 8,000 bridges in the U.S. that are both structurally deficient and fracture critical. That means that an average of 160 bridges per state pose the same danger to the traveling public and commercial carriers that the I-35W Bridge posed prior to its collapse. For too long, federal and state leaders have done little, if anything, to address this danger to the public.

The Save Our Bridges Map was created based on public documents that were issued by the Federal Highway Administration in 2009 but were not accessible to the general public. For the public’s information, the FHWA contains only charts that show bridges that are structurally deficient (“poor”) or fracture critical (“bridge not meeting current design standards”).

There are 600,000 bridges listed on the FHWA’s National Bridge Inventory. The Save Our Bridges Map pinpoints the 7,980 bridges the FHWA listed as being both structurally deficient and fracture critical that have been omitted from the 2010 and subsequent reporting on the NBI site.
