Washington, D.C. ? Federal officials alerted states Thursday to immediately inspect all bridges similar to the Minneapolis bridge that collapsed into the Mississippi River.

Transportation Secretary Mary Peters approved an advisory that was sent by the Federal Highway Administration urging state transportation departments to conduct inspections of bridges similar to the steel-deck truss bridge that collapsed Wednesday.

There are 756 such spans, according to highway officials. No list of bridge locations was available.

Kansas has 15 such bridges, according to a 2006 report. However, it was unclear whether any of those bridges is in Douglas County.

The bridge that collapsed during rush hour Wednesday evening was built with a single 458-foot-long steel arch to avoid the need for piers that might interfere with river navigation.
