State bridge inspections are typically done biennially. As a result, there may be a substantial time lag with the data we are presenting, which was obtained from information taken from the National Bridge Inventory prepared by the Federal Highway Administration in 2009.

Therefore, in order to present the most relevant and timely condition data possible, we urge state DOTs to contact us if any bridge we highlighted is no longer considered structurally deficient due to remediation or replacement.
