The Causeway, the longest bridge in Louisiana that spans over Lake Pontchartrain, has been shut down for more than 7 hours Tuesday after dense fog led to a series of crashes during rush hour. 

At least six crashes were reported involving dozens of cars. 

Many involved in the crash felt trapped on the bridge in the aftermath as they waited for officials to clear the lanes and help get them to safety.

Paul Becnel of Old Jefferson had to climb out of the window of his wrecked vehicle and went to an area emergency room to get checked out. 

“There wasn’t no getting out of either door,” he said. “It looks like there was a mess everywhere.”
