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 in summer 2021. 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 began in May 2017 and was completed in December 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 in late 2019, and work is estimated for completion in summer 2022, 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.
