UPDATE: As of 4 p.m., US 90 is now open after a crash closed the eastbound and part of the westbound Wednesday afternoon.
Earlier Wednesday, U.S. 90 was partially closed near Bayou Vista after a crash.
At that time, Troopers said that both eastbound lanes were shut down and westbound lanes were partially closed after a crash involving a tractor-trailer rig and an SUV.
Diesel fuel had leaked onto the road from the 18-wheeler, and the road was closed for clean-up.

Troopers say it could take several hours.
Motorists are advised to take an alternate route if they can and if they can't expect delays.
