A body has been found in Lake Pontchartrain, according to the Jefferson Parish Sheriff's Office.
WDSU, the NBC affiliate out of New Orleans reports the sheriff's office did not confirm that it was the body of a driver who drove over the causeway railing Monday.
The sheriff's office says an autopsy will help determine who the person is.
A truck traveling southbound went over the railing and into the water around 4 p.m. About two miles from the Southshore.
The truck ricocheted between the guard rails before going over, according to the witness.
Another eyewitness said the truck didn't have any other vehicles around it at the time it went over the railing.
Another eyewitness said a man surfaced but went under moments later.
The Coast Guard and Jefferson Parish deputies had been searching for the driver.
