Widening of I-10 to Hwy 73 nearing completion

Staff Report

Construction crews are nearing the end of their work on DOTD’s On the Greaux project to widen Interstate 10 between Highland Road in Baton Rouge and La. 73 in Ascension Parish.

Construction crews are nearing the end of their work on DOTD’s On the Greaux project to widen Interstate 10 between Highland Road in Baton Rouge and La. 73 in Ascension Parish.

Currently, all six lanes will be open for some periods of time with intermittent lane closures to finish and finalize the project. After some nighttime and weekend work to complete striping and guardrails, all six lanes of traffic along the 6.5-mile I-10 segment should be fully opened by the end of October, providing increased capacity for the nearly 100,000 vehicles that travel the corridor each day.

“This portion of I-10 is a critical freight corridor for Baton Rouge and New Orleans and a daily commuter route for thousands of residents,” said DOTD Secretary Shawn D. Wilson, Ph.D. “Increasing the capacity will mitigate traffic congestion and encourage economic development in the region. This success story is an example of what the state can do when we are provided the resources.”

Construction for the $72 million project began in February 2018 and includes new interstate bridges above Highland Road and at Bayou Manchac. The project was executed as a design-build project, a delivery method that allows the contractor and designer to work concurrently. This approach compresses the time it takes to complete the project, from planning to final delivery.

To complete the project, lane closures will take place on nights and during the weekend to accommodate crews that are installing guardrails, applying permanent striping and performing other items to close out the job. For more details on the project, visit the On the Greaux lane closure calendar.
