Port Allen- The Louisiana Department of Transportation and Development continues to make progress on the LA 1 Intracoastal Bridge replacement project in West Baton Rouge Parish.

Crews are currently working on the substructure of the bridge, which includes the bridge columns and footing, as well as road work for the upcoming scheduled traffic shift from LA 1 southbound onto the new alignment coming from the new bridge and drainage along LA 1. Additionally, crews are performing work for future dynamic message signs and traffic cameras.

In order to install drainage structures along the LA 1 median, there will be alternating lane closures daily from now until August 19 from 7 p.m. to 4 a.m. Southbound LA 1 near the Intracoastal waterway will have alternating lane closures, which northbound will have intermittent left lane shoulder closures.

This $57.7 million project, which began in April 2022, will replace the current southbound bridge with a new bridge that will be constructed on the west side of the existing structure, in addition to realigning Ernest Wilson Drive and LA 1 to connect with the new bridge.

The second phase, which is scheduled to go to bid summer 2023, will remove both of the existing original bridges and construct a new northbound bridge, as well as replace frontage roads on the south side of the bridge. Once both phases are completed, there will be a new southbound bridge that has three 12-foot lanes and 10-foot shoulders and a new northbound bridge with two 12-foot lanes and 10-foot shoulders and a barrier separated exit lane for I-10 eastbound.

The contractor, Kiewit Louisiana Co., is anticipated to be completed with phase one summer 2023, weather permitting
