The Louisiana Department of Transportation and Development (DOTD), advises the public that beginning Monday, April 10th, 2023 construction will begin on LA 485’s Site 4 Bridge in Natchitoches Parish and it will be closed to through traffic. This work will take place on LA 485: 1.9 miles east of the intersection of LA 485 and 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.
Beginning April 10th, the Site 4 Bridge will be closed to traffic. Related work will includes removing the existing timber trestle bridge, installing bedding material, setting reinforced concrete box culverts, pouring headwalls, placing riprap, back filling the roadway, class II base course, 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 Four (4) is expected to be completed by the end of September 2023.
