NEW ORLEANS -- USACE held a final inspection for the Mississippi River Levees (MRL) Harvey Lock Forebay Floodwall Tuesday, Aug. 26, 2025. Since construction is completed, Destrehan Avenue in Harvey, La., will be open to traffic starting Thursday, Aug. 28, 2025.
Public safety remains our top priority, and we appreciate your patience as we wrapped up construction on this critical flood risk management project.
USACE awarded the $3.7 million construction contract in September 2024, and this contract included construction of a floodwall intended to provide flood-risk reduction to Jefferson Parish, La. The existing elevation of this levee will be raised 3 feet by placing a pile founded concrete T-wall from south of Riverfront Park to near the Harvey Lock as part of the overall Mississippi River Levees construction project.
This MRL construction project is a part of the larger Mississippi River and Tributaries project. The system is intended to provide flood-risk reduction to the vast expanse of the developed alluvial valley from periodic overflows of the Mississippi River. The mainstem levee system begins at the head of the alluvial valley at Cape Girardeau, Mo., and continues to Venice, La., approximately 10 miles above Head of Passes near the Gulf of America.
