About the Project

The I-49 Lafayette Connector is a future 5.5-mile segment of highway that will extend I-49 from I-10 to the Lafayette Regional Airport. It is a critical transportation link for Lafayette and the state as a whole. The I-49 Lafayette Connector is a key component of I-49 South, which will function as a critical hurricane evacuation route, complete a major energy and trade corridor to the nation and enhance safety by providing new interstate connectivity within the Lafayette region and to New Orleans. For more information about the project and planning, visit the Project Overview.

Our Philosophy

The I-49 Lafayette Connector project is an initiative rooted in community collaboration. It presents the opportunity to revitalize and beautify Lafayette’s gateway, strengthen infrastructure and improve safety and multi-modal transportation, all while preserving the community’s cherished, historic and business districts. It truly represents Acadiana’s path forward.

Project Update

The I-49 Lafayette Connector Project has reached an important milestone with the publication of the Draft Supplemental Environmental Impact Statement (DSEIS). Prepared by the Louisiana Department of Transportation and Development (DOTD) in coordination with the Federal Highway Administration (FHWA), the DSEIS evaluates the proposed project, including its design features, right-of-way considerations, consistency with local planning goals, and potential social, economic, and environmental impacts.

As part of the National Environmental Policy Act (NEPA) process, an Open House and Public Comment Session was held on Wednesday, September 2, 2026, to provide the public with an opportunity to review project information, ask questions, and submit comments. The official transcript and meeting materials are now available on the project website. The public comment period for the DSEIS has been extended through December 22, 2026. Comments may be submitted through the comment form on this website or by emailing comment@lafayetteconnector.com. All comments received during the official comment period will be reviewed and addressed in the Final Supplemental Environmental Impact Statement (FSEIS).
