With the Finding of No Significant Impact by FHWA in early 2021, Segment 1, the first construction segment of Phase I, is nearing final design. This part of the corridor is most challenging because it traverses the heart of Baton Rouge within a constrained footprint. It is a priority because improvements to this segment will provide the greatest benefits to Baton Rouge and interstate travelers generally by providing 4 lanes of interstate in each direction, including two lanes eastbound where I-10 joins I-110. Construction began in 2023 with utility relocations, soon followed by a temporary westbound lane addition from Acadian to I-110 and a permanent lane addition to the I-10 westbound curve towards the Mississippi River Bridge at I-110.
DOTD is continuing to engage the public through this process. An open house event was held Tuesday, March 7, 2023 exhibiting numerous design modifications to be included in a Reevaluation Request to the Federal Highway Administration as an addendum to the environmental documents.
