Project Update: Atchafalaya Basin Bridge rehabilitation project
Thursday, January 23, 2020 at 10:02:34 AM
St. Martin Parish- The Louisiana Department of Transportation and Development announces an updated schedule for a rehabilitation project to replace the existing bridge deck surface on the Atchafalaya Basin Bridge in St. Martin Parish from the Whiskey Bay exit to mile marker 125. Roadwork has been suspended for the weekend of Jan. 24 to Jan. 27. The contractor will resume construction on Jan. 31 where the right lane of I-10 westbound will be closed from 9 p.m. on Friday to 6 a.m. on Monday.

This project, which consists of milling the existing deck surface and replacing it with a modified latex concrete pavement, is estimated to be completed Feb. 3, weather permitting. Motorists are encouraged to use a detour route using LA 415 to U.S. 190 to I-49 back to I-10.

A portion of the bridge deck was damaged following a multi-vehicle crash involving a vehicle fire in August 2019 that caused spalling to occur, resulting in some of the surface concrete to crack and flake off. The bridge was deemed structurally sound after a thorough bridge inspection.
