Those trips home after a LSU home game could take a little longer if you're planning to use I-49 to take you through the Natchitoches area.

In a notice from the Louisiana Department of Transportation and Development, drivers are advised that beginning tomorrow, October 30, construction will begin on an emergency pipe repair project on I-49 northbound in Natchitoches Parish.

This work will take place approximately 3 miles north of exit 119 near Montrose.

DOTD highlights that the intent of this project is to rehabilitate three 120” corrugated metal pipes at Bayou Lacarp which is located under I-49. This includes repairing damaged areas and applying a geopolymer lining along the inside of the pipes.

Geopolymer lining is a highly durable material that – once applied to the inside of the pipe - hardens and bonds with the existing structure to create a protective seal and reinforce the pipe’s integrity.

In order to allow construction to progress safely and efficiently, the northbound outside lane of I-49 will be closed.

The work associated with this project should wrap up in early 2026, with progress dependent on weather conditions and other factors that can impact construction timelines.

DOTD appreciates your patience and reminds you to please drive with caution through the construction site and be on the lookout for work crews and their equipment. Remember to leave plenty of room between you and the vehicle in front of you. and never drive while distracted or impaired.
