In the street view below, they are building the $57.7m phase one bridge. It was supposed to be completed in early 2023. [wbrparish]

Given the big gap still in the bridge in Mar 2024, they did not meet the original schedule.

Construction was halted in Spring 2023 "after DOTD found that the piers for the bridge were sinking more than expected.Since then, a fix was engineered, and the contractor, Kiewit Construction, has had a sub-contractor working on low mobility grouting to stabilize the piers. That is expected to be completed before the end of this year. Kiewit will begin construction work on the bridge again in early 2024." Phase one should be done by the end of 2024. [wafb]

Kiewit Corporation posted four photos with the comment:

Progress continues in West Baton Rouge Parish as we work on constructing the new southbound LA-1 Intracoastal Bridge.

The construction of the southbound bridge is Phase 1 of a two-phase project to replace the existing bridges built 60 years ago. The new bridges will provide additional lanes and wider shoulders for more accessibility and safety, help with traffic congestion and be a more efficient route for hurricane evacuations in Louisiana. 

Kiewit is the general contractor on Phase 1. Phase 2 includes the demolition of the old bridges and the construction of the new northbound bridge.

The new bridge uses steel girders in the middle and concrete girders on the ends.
