Traffic will be disrupted even more than usual along Jefferson and Nashville avenues beginning this week as the U.S. Army Corps of Engineers continues work on the Southeast Louisiana Drainage Project.

The northbound lane of Jefferson Avenue between Perrier Street and St. Charles Avenue will close to traffic on Thursday. Northbound traffic will be diverted at Perrier to Coliseum Street while contractors install steel sheet piling and prepare the ground for a drainage box culvert.

Meanwhile, traffic will be closed on Jefferson north of St. Charles Avenue to allow for the construction of a manhole and drain line into the culvert.

The Jefferson Avenue closure is expected to last six weeks. The Army Corps said its contractor will try to have the lanes open before the start of the 2015 Carnival parade season.

Also beginning on Thursday, Nashville Avenue at Prytania Street will be reduced to one lane in each direction as work begins on another culvert. That project is expected to last six months.

The Southeast Louisiana Drainage Program is aimed at reducing flood damage in New Orleans and surrounding parishes by building new pumping stations and better drainage canals. The project is administered through a cooperative endeavor agreement between the Sewerage & Water Board and the Corps of Engineers.
