Project Info

The purpose of the corridor study is to identify system deficiencies contributing to congestion patterns throughout the I-10 corridor from west of the Mississippi River to the I-10/I-12 split and develop solutions. Concepts to address these system deficiencies were developed as part of a comprehensive public initiative designed to capture public input in advance of, during, and after alternative development. The feasibility of these concepts was analyzed and documented as part of a Stage 0 Report prepared in accordance with DOTD guidelines. These concepts were brought forward into the environmental review process (Stage 1) required as part of the National Environmental Policy Act of 1969 (NEPA).

The Stage 1 Environmental Assessment (EA) was released for public review in October 2019. Public Hearings were held to present the findings of the EA in November 2019. A Finding of No Significant Impact (FONSI) is anticipated to be released in the first quarter of 2020. Please see the links below to view the documents that comprise the EA as well as the materials presented during the public hearings and the responses to comments received on the EA.

As project documents become available they will be added to the list below. The most recent uploads will be listed first.
