The Belle Chasse Tunnel is closing for a week for work to stop groundwater from leaking into the tunnel.

The Army Corps of Engineers says the tunnel will close overnight — from 7 p.m. until 5 a.m. — from Monday through Thursday. It will close 24 hours a day over the weekend, starting at 7 p.m. Friday and reopening at 5 a.m. on Monday, March 18.

The corps says more work will be needed to fully eliminate seepage, but the tunnel is expected to stay open after March 18.

State transportation officials say the Belle Chasse tunnel on Louisiana Highway 23 will be closed until Monday at 5 a.m. Crews are working on the floodwall at the site, officials say.

The Perez Bridge will handle two-way traffic while the tunnel is closed.
