LA 3241: I12 to Bush, St. Tammany Parish

Project Description
The project calls for the construction of a new four-lane highway connecting I-12 to Bush, Louisiana, in St. Tammany Parish. The new roadway is approximately 19.8 miles in length and begins at LA 434, north of the existing LA 434 interchange with I-12, and traverses in a northeasterly direction until encountering an abandoned rail corridor. It then follows the rail corridor terminating at the LA 21/LA 41 intersection near Bush, Louisiana.

Current Status
On April 12, 2016, FHWA issued its Record of Decision (ROD). FHWA adopted the Final Environmental Impact Statement (FEIS) prepared by the U.S. Army Corps of Engineers (USACE) wherein the alignment, alternative Q, for the captioned project was selected. This adoption enables the Department to use Federal funds to construct the project. The Adopted FEIS and ROD can be accessed at the link below. The Department hosted an open house meeting during the FEIS comment period to share information about the project. The public meeting transcript is also available at the link below.

The project is under design and is broken into three design projects.
