Over the past several years, most (but not all) states made strides in reducing their inventory of bridges in poor condition.

Friday marked the seven-year anniversary of the I-35 bridge collapse in Minneapolis. The tragedy and subsequent bridge failures have helped focus public attention on the issue, leading some lawmakers to support additional investment in infrastructure.

A Governing story published in June examined how some states managed to significantly cut their tallies of structurally deficient bridges.

In the six years following the Minneapolis collapse, the number of structurally deficient bridges declined 14 percent nationwide.

To view trends for a particular state, select it in the menu below. Charts illustrate changes for structurally deficient and functionally obsolete bridges for the past 20 years.

Bridge Inspections Definitions:

  • Structurally-Deficient Bridges: Bridge had deterioration of one or more major components, but is not unsafe.
  • Functionally-Obsolete Bridges: Bridge was built using outdated standards, such as older design features.
