The Coast Guard has recovered the body of a Franklinton man whose pick up truck went into Lake Pontchartrain after plunging off the Causeway Bride early Wednesday morning.

Causeway bridge manager Carlton Dufrechou told Eyewitness News Christopher Knight's body was found before sunset on Wednesday afternoon. The Jefferson Parish coroner confirmed it was the 41-year-old man Thursday.

Dufrechou said that it is believed the man is a resident of a small community near Bogalusa.

Investigators believe the truck crashed into the guardrails near mile marker 12 shortly after 3:30 a.m. Drivers traveling southbound found debris in the roadway and about 25 feet of guardrail missing.

A search started shortly after once the Coast Guard and other emergency crews arrived on scene.

Search efforts in the area were hampered by early morning darkness. Divers were able to find the vehicle after 6 a.m.

The investigation of the crash will continue and according to Dufrechou there might be a short shut down of the southbound lane of the Causeway this weekend due to the continuing investigation.

The Coast Guard, the Causeway Police, the St. Tammany Parish Sheriff's Office and the Jefferson Parish Sheriff's Office assisted in the search.

Both southbound and northbound lanes of the bridge are open in both directions.
