LAFAYETTE, La. - The Louisiana Department of Transportation and Development announces an upcoming traffic shift on I-10 westbound, between Henderson and Bordelon Road overpass, in St. Martin parish.

The traffic shift will take place beginning Sunday, October 18, at 8 p.m. until Monday, October 19, at 6 a.m.

Motorists traveling on I-10 westbound will shift to newly constructed lanes in the median. This traffic shift is necessary to allow crews to remove the existing westbound bridge over Melvin Dupuis Road and to construct new I-10 westbound lanes. Crews will also begin working on the new Melvin Dupuis overpass over I-10 during this next phase of construction.

Prior to the traffic shift, alternating lane closures will be used to accommodate the shift and perform necessary pavement striping. Temporary pavement striping for the new traffic configuration will also take place on the I-10 westbound entrance ramp. To perform this work, the ramp will be temporarily closed beginning Sunday, October 18, at 11 p.m. until Monday, October 19, 4 a.m.

Motorists traveling on La. 347 (Grand Point Hwy.) wanting to take I-10 westbound during the temporary closure will need to travel south on La. 347 (Grand Point Hwy.) to the I-10 eastbound entrance ramp, go east on I-10 to Exit 121 (La. 3177 - Butte La Rose), and then travel west on La. 3177 (Atchafalaya River Hwy.) to I-10 westbound.

DOTD appreciates your patience and reminds you to please drive with extreme caution through the construction site and be on the lookout for work crews and their equipment.
