Rocks Bayou Bridge will be closed to through traffic beginning Nov. 9.


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. This work will take place on LA 485: 0.25 miles west of its intersection with I-49.  

The intent of this project is to remove and replace seven bridges in four sites along LA 485. Three of the sites are located west of I-49 and one site is east of I-49. Each of the sites will be closed to through traffic with no onsite diversions, but only one site may be closed at a time.

On November 9th, only the Rocks Bayou Bridge will be closed to traffic at this time. Related work will includes removing existing timber trestle bridges, installing embankment, constructing new concrete slab span bridges and concrete box culverts, class II base course, guardrail, hot mixed asphalt pavement, permanent striping and other related work.

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.
