Database of the day: National Bridges – Deficient or Obsolete

Although the Federal Highway Administration collects all kinds of data on the condition of bridges it’s not presented in a consumer friendly format. You can download files by Deficient Bridges by State and Highway System, Highway Bridge by Owner or Bridge by State.

Query the citizen run National Bridge Inventory Database, which has been overwhelmed with hits since the recent Minneapolis collapse, for any bridge data, but here’s Minneapolis NBI Structure 9340.

A Deficient or Obsolete Bridges database with a state by state map has been assembled by MSNBC. Select a state, then click on the small type link, “Click here to see major state bridges on list”. Find out whether the bridge is obsolete or deficient (an engineering distinction, both of which sound bad) and its safety rating. Keep in mind that the last structural evaluation for the Minneapolis bridge concluded: “Meets minimum tolerable limits to be left in place as is”.

    Then it seems this database is not accurate, therefor not very useful. It can only be as accurate as the people inspecting/reporting the conditions.
