The West Pearl River Bridge (map #87, west of Pearlington, Louisiana) is indefinitely closed to all traffic after inspectors found significant deterioration of the deck supports during a routine inspection. Read the DOT’s emergency announcement here.
There are no easy detours around the closure for bicyclists. One option is to get a ride or rent a vehicle to drive across I-10 using the posted vehicle detour. Bicyclists are prohibited from riding on I-10 and I-59.Eastbound Detour Map Westbound Detour Map You may have already ridden the Southern Tier, and this alert no longer concerns you.

The highways in Louisiana generally have good shoulders, but the highways in Mississippi have narrow to non-existent shoulders. We tried to use backroads as much as possible. Maps of the detour:
