Contractors will begin work Tuesday on a two-year, $6.3 million street-widening and drainage project on a half-mile stretch of Ames Boulevard in Marrero.

The stretch involved is a predominantly residential portion south of Barataria Boulevard.

Crews with Barriere Construction Co. will replace the concrete pavement, add a center turning lane and eliminate the steep roadside ditches, which should make the street safer for motorists.

The drainage work includes the installation of subsurface drainage designed to withstand a 10-year storm.

Other work includes utility relocations, traffic signal improvements and permanent striping.

Also on Tuesday, Boh Bros. Construction Co. crews are scheduled to begin work on the third phase of drainage improvements to the south side of Carol Sue Avenue in Terrytown.

That $3.9 million project will continue through Nov. 19 and will close the eastbound lines of Carol Sue between Oakwood Drive and Behrman Highway from 7 a.m. to 4 p.m. weekdays.

Vehicles headed to Behrman on Carol Sue will be redirected to Oakwood Drive, Guardian Avenue and Matador Drive.

The westbound lanes of Carol Sue will remain open.
