I-10 Westbound Flyover Widening

Baton Rouge – The Louisiana Department of Transportation and Development (DOTD) announces an update on the I-10 widening project in East Baton Rouge Parish. In order to mitigate traffic concerns regarding lane restrictions associated with the widening project, with the approval of the Federal Highway Administration, DOTD will construct an additional lane on the westbound flyover at the I-10/I-110 interchange.

Once approved, construction of this additional lane will take approximately one year to build and will cost an estimated $50 million. Lane restrictions along I-10, which were estimated to begin in early 2024, will be pushed back a year until the lane is fully constructed. The lane restrictions were instituted into the project in an effort to save up to 4 years of construction and more than $50 million in costs. This mitigation measure of adding a westbound lane on the flyover has been about a year in the making as engineers worked to determine feasibility, constructability and cost benefits.

“DOTD has been working diligently to determine the most feasible options to reduce traffic congestion during the construction of the widening project. With the $50 million saved, which derived from the contractor proposal to extend the project to Acadian Thruway with the lane restrictions, we will be able to provide more travel lanes over the westbound flyover,” said DOTD Secretary Shawn D. Wilson, Ph.D. “While this project will be extended by a year, we will continue to make improvements to other highways in the region as mitigation that would not have been possible. Let’s not lose focus on the end goal, which is to make these much-needed enhancements to the I-10 corridor. When this project is completed, it will be transformative for the region and the state.”

Once completed, there will be four lanes in each direction from the I-10/I-110 split to Acadian Thruway. Construction is scheduled to begin in 2023 and is estimated to be completed in 2028, weather permitting.
