A US bridge was forced to close after being hit by the antenna of a tanker.

The incident under the Huey P Long bridge in Elmwood, Louisiana, involved the 113,000-dwt aframax Clio (built 2008) on Wednesday, the New Orleans/Baton Rouge Steamship Pilots Association told WWL-TV.

The span was closed for three hours, but only suffered superficial damage, according to the Causeway Police Department.
