Coast Guard crews are ending their search for a vehicle they thought might be in Lake Pontchartrain, officials said.
They found no evidence of a vehicle in the water.
The Coast Guard responded after authorities reported a damaged guardrail about 3:45 a.m. Thursday, following a multi-car crash on the Lake Pontchartrain Causeway, according to a press release from the Coast Guard.
The crash occurred at mile-marker 3 in the southbound lanes.
Boat and helicopter crews participated in the search.
