Bridge

Deficient Bridges by State and Highway System 1996

Note: The "10 Year Rule" was applied in the determination of deficiency status within these data tables. The "10 Year Rule" excludes bridges built or reconstructed within the past 10 years since they are not generally eligible for Highway Bridge Program funding.
