Barges strike Mississippi River bridge in Hannibal

Hannibal, MO – Authorities in Hannibal say the Mark Twain Memorial Bridge over the Mississippi River appears sound after being struck by runaway barges.

An American Commercial Lines tugboat with 12 barges struck the center span of a railroad bridge Monday afternoon. The barges then broke loose and some struck the bridge that carries Interstate 72 traffic over the river.

It wasn't immediately clear what the barges were carrying. The runaway barges threatened to strike an excursion riverboat in Hannibal, but the operator was able to dodge them.

Hannibal emergency management director John Hark said state inspectors found no significant damage to the I-72 bridge.
