The Louisiana Department of Transportation and Development, (DOTD), advises the public that on Wednesday, November 9th, 2022 construction will begin LA 485’s Rocks Bayou Bridge in Natchitoches Parish and it will be closed to through traffic.

The public is advised to remain alert to construction signs and changing roadway conditions along LA 485.

The project was awarded to the low bidder, Merrick, LLC, of Cottonport, LA in the amount of $13,727,495.43 and will take approximately 700 calendar days to complete all four sites. Site Three (3) is expected to be completed by the end of September 2023.
