The Louisiana Department of Transportation and Development is replacing both the Cheniere Lake spillway and attached bridge on LA 3033 in West Monroe, Ouachita Parish. The project began in February 2021.

A total road closure is necessary on LA 3033 to allow construction on the removal of both structures. LA 3033 will be closed through mid-2022, the duraiton of the project.

The $16.5 million project is completely replacing the bridge over Cheniere Lake, as well as removing and replacing the currently attached spillway structure that's owned and maintained by the Ouachita Parish Police Jury.

"The key to the success of many of our projects is our partnership with local government, and this project is a prime example," said DOTD Secretary Shawn D. Wilson, Ph.D. "It's imperative that both of these structures, the bridge and the spillway, remain in service for the community for many more years, so I applaud everyone who worked diligently to develop and bring this project to construction."

As part of this project, the bridge - owned and maintained by DOTD - is being replaced on its existing alignment. But the new cost-effective spillway will be a fixed crest weir offset from the bridge. This will be a much-improved placement for each structure that will reduce the inconvenience to the traveling public during routine maintenance and other necessary work on the spillway.

Dedicated drainage improvement funds are making possible the construction of the new drainage system that will allow for much more efficient water level control and maintenance activities on the lake. Cheniere Lake will continue to be managed by the Ouachita Parish Police Jury.

The entire project is expected to be complete in early 2024, with progress always dependent on weather conditions and other factors that may impact construction timelines. 

Detour information: Detour signage will be in place directing motorists to use LA 34 (Jonesboro Road) and LA 840 (Smith Street) to access LA 3033.
