I-10 Widening from I-49 to Atchafalaya Basin Bridge

The widening project consists of three separate projects.

The first project is a $124.7 million project along I-10 from I-49 to LA 328 (Breaux Bridge) which is estimated to be completed September 2020. Funding was sourced federally, with $60 million funded through the FASTLANE Grant. The 7.11 mile widening of I-10 from the east junction of I-49 to La. 328 consists of adding an additional lane and a 16-foot shoulder, with a 54-inch median barrier on both the east- and west-bound lanes. Additionally, the project will include widening five structures (bridges/ overpasses) and replacing the structure at La. 328 to increase the span length.

The second part of this widening is a $54.69 million project that spans from LA 347 to the Atchafalaya Basin Bridge. Construction in July 2017 and is estimated to be completed 2020.

The 2.4 mile widening on I-10 from LA 347 to the Atchafalaya Floodway Bridge consists of adding an additional lane westbound, as well as a 54-inch median barrier on both the east- and west-bound lanes.

The third phase is an $87.7 million project that spans between LA 328 and LA 347. The contractor, Gilchrist Construction, began late 2019 and work is estimated to take three years, weather dependent.  This 4.5-mile project will widen I-10 from four to six lanes between LA 328

Once complete, this widening project will help alleviate congestion in a heavily traveled interstate that sees heavy freight traffic. This is a major freight corridor and connector for those traveling between Texas and Mississippi, as well as from our major southern cities and has not been improved in decades.
