DOTD announces I-10 EB traffic shift on I-10 widening project in St. Martin Parish

The Louisiana Department of Transportation and Development announced that I-10 eastbound traffic from LA 347/Henderson to the Atchafalaya Basin Bridge will shift to the newly constructed eastbound lanes on Thursday, May 7 beginning at approximately 8 p.m.

At approximately 8 p.m. both eastbound ramps at LA 347 will be closed to traffic, and there will be alternating left and right lane closures to accommodate the traffic shift. By 6 a.m. Friday, May 8 the traffic shift will be complete and all lane closures related to the shift will be removed.

Crews have completed reconstruction of the eastbound travel lanes and will now work on completing the concrete median barrier, guardrails, bridge deck joint repairs, and the interchange lighting system. Additional upcoming work includes placing the final layer of asphalt on LA 347 and I-10, as well as drainage improvements.

Once complete, this project will replace pavement within the existing lanes in each direction for 2.7 miles along I-10 from LA 347 to the base of the Atchafalaya Basin Bridge. A third lane will be added in the westbound direction.

The $55 million project is anticipated to be complete in Fall 2020. It is partially funded by a $60 million FASTLANE grant received from the United States Department of Transportation in July 2016. With the help of the FASTLANE grant, this is one of several projects to reconstruct and widen the I-10 corridor from I-49 to the Atchafalaya Basin Bridge.
