BRIDGE CLOSURES: LA 485 Little River & Relief Bridges, Natchitoches Parish

The Louisiana Department of Transportation and Development advises motorists that beginning on Monday, February 19, 2024, the Little River, as well as three Little River Relief bridges, on LA 485 in Natchitoches Parish will close as part of an ongoing $13.7 million project to replace several bridges along this route.

This work will take place approximately 3.3 miles north of the intersection of LA 485 and LA 6. All four of these bridges are located within a mile of each other, which will be closed to through traffic to allow this work to be conducted.

Additional work includes removing the existing timber trestle bridge, building four new slab span concrete bridges, placing rip rap (large stone material used to stabilize and protect the soil surface), embankment work, roadway base and asphalt, and permanent signage and striping.

Also as part of this project, on February 15, 2024, Site 2 that is located approximately 1.75 miles west of I-49 that has previously been under construction will be opened to traffic.

The entire project is anticipated to be complete in late 2024, with progress dependent on weather conditions and other factors that can impact construction timelines.

Alternate Routes:

Northbound traffic will be detoured west on LA 6 to I-49 north to LA 485.
Southbound traffic will be detoured south on I-49 to LA 6 east to LA 485.

Safety Reminder:

DOTD appreciates your patience and reminds you to please drive with caution through the construction site and always be on the lookout for crews and their equipment.
