I-10 Mississippi River Bridge closure, new lane configuration

Wednesday, August 4, 2010 - 3:14pm

BATON ROUGE, La. – The Louisiana Department of Transportation and Development (DOTD) announced today that the I-10 Mississippi River Bridge will be closed to traffic from 1 a.m.- 8 a.m. on Sunday, August 8, 2010, to allow crews to hang overhead sign trusses as part of an ongoing sign replacement project. The closure includes the eastbound and westbound lanes of the bridge. The total closure is needed to give workers enough room to safely install the overhead sign trusses that span across all lanes of the bridge.

Detour routes:

  • I-10 westbound traffic will be detoured to I-110 North to U.S. 190 West to La. 1 South to I-10 West. I-10 eastbound traffic will be detoured to La. 1 North to U.S. 190 East to I-110 South to I-10 East.
  • An alternative detour route for I-10 westbound will be I-10 West to I-110 North to U.S. 190 West to La. 415 South to I-10 West.
  • An alternative detour route for I-10 eastbound will be I-10 East to La. 415 North to U.S. 190 East to I-110 South to I-10 East.

Additionally, permanent lane adjustments to the I-10 Mississippi River Bridge will go into effect immediately following the closure, on Sunday at 8 a.m. At that time, all I-10 westbound traffic crossing the Mississippi River Bridge exiting to Port Allen and Plaquemine will use the outer lane prior to exiting. Traffic in the westbound center lane will no longer be able to exit, as this lane will serve only westbound through traffic.

The lane adjustments are being implemented as part of the ongoing I-10 Mississippi Bridge signing and striping project, and will help to improve traffic flow on the bridge.
