Should Lafayette build the $2 billion I-49 Connector highway?
The Federal Highway Administration extended the public comment period on the Lafayette I-49 Connector Draft Supplemental Environmental Impact Statement to Dec. 22, up from the earlier Sept. 12 deadline. Comments may be submitted through the project form or by email, and will be addressed in the final document.
Why it matters
The proposed 5.5-mile interstate section would reshape travel between Lafayette Regional Airport and Interstate 10 and is part of a broader plan to extend I-49 from Canada to New Orleans. Residents who requested re-evaluation of the route prompted the current supplemental review.
The proposed Connector is a 5.5-mile partially elevated six-lane interstate with an estimated cost of about $2 billion as of 2023, and the first phase at Kaliste Saloom is estimated at $350 million. Two design options remain under review, and the final choice has not been made.
The players
Federal Highway Administration
The federal agency within the U.S. Department of Transportation that oversees the federal-aid highway program and is conducting the environmental review for the Connector.
Louisiana Department of Transportation and Development
The state agency responsible for planning, building, and maintaining Louisiana's transportation infrastructure, which has endorsed the roundabout design for the Connector.
Lafayette Consolidated Government
The local government of Lafayette, Louisiana, which has endorsed the roundabout design for the proposed Connector.
The details
The Federal Highway Administration extended the public comment deadline to Dec. 22 for the Draft Supplemental Environmental Impact Statement on the Lafayette I-49 Connector. Comments can be submitted at www.lafayetteconnector.com or by email to comment@lafayetteconnector.com and will be reviewed in the Final SEIS.
Timeline
January 2003: The FHWA issued a Record of Decision on an earlier version of the Connector.
July 2015: Planning restarted after hundreds of people requested re-evaluation of the route.
Sept. 12: Previous public comment deadline.
Dec. 22: Extended public comment deadline.
First quarter 2027: The FHWA expects to issue the Final SEIS and Record of Decision.
Market Landscape
The Connector is a segment of the broader I-49 extension plan linking Canada to New Orleans, a corridor whose Lafayette section was first approved under the 2003 Record of Decision. The current review revisits that approval after the 2015 re-evaluation requests, shaping how this long-planned corridor advances through Louisiana.
Drivers using the Kaliste Saloom area near the airport and the I-10 corridor could see a six-lane elevated interstate once construction begins, but timing depends on funding. Residents can submit comments through the project form by Dec. 22 to influence the final design choice between roundabouts and traffic signals.
The takeaway
Public comment is the window for residents to weigh in on the roundabout versus signal design before the final decision. Comments must be submitted by Dec. 22 to be considered in the Final SEIS.
What happens next
The Federal Highway Administration expects to issue the Final SEIS and Record of Decision in the first quarter of 2027, after which the project will proceed as funding becomes available.
