DES MOINES, Iowa (AP) – A railroad bridge across the swollen Mississippi River in southeastern Iowa partially reopened Friday, more than a day after it was struck by a grain-filled barge.

The BNSF bridge at Burlington is part of a main rail for freight and passenger traffic, and its closure has disrupted schedules for more than 100 trains, BNSF Railway spokesman Steve Forsberg said.

The barge remained pinned against the bridge Friday, but the line on the south side of the bridge opened before noon, Forsberg said. The other line was struck by the barge and remained closed.

“That track suffered damage, and that will take a couple of days to repair,” he said. “Until that is repaired, we’ll be at restricted speeds.”
