Plaquemines Parish, La. - The Louisiana Department of Transportation and Development (DOTD) announces that construction is expected to begin by the end of May 2026, weather permitting, on a new roundabout at the intersection of LA 406 and F. Edward Hebert Boulevard in Plaquemines Parish.
The $3.2 million project will improve traffic flow, reduce congestion, and enhance safety for motorists traveling through the area. Construction is currently expected to be complete during the second quarter of 2027.

The program funds critical maintenance and projects that improve infrastructure safety and reliability across Louisiana.
