Less than a decade after crews fixed up Windward Parkway at Ga. 400, workers are about to get back to it.

The North Fulton Community Improvement District and the city of Alpharetta will break ground Thursday on an 18-month project to add lanes to the area to reduce congestion.

The CID said on its website that the project will cost $5.7 million, with a mix of funds from multiple agencies: the Georgia Department of Transportation, State Road and Tollway Authority, Fulton County and the city of Alpharetta.

The CID — which is a self-taxing district of businesses that works to improve the area — plans to spend $620,000 on the project, said Daniela Tawil, who handles marketing for the CID.

Crews will add a third left-turn lane at Windward Parkway that will extend westbound along Windward to Deerfield and Westside parkways.

Tawil said there would be sporadic road closures required to finish the project.

In December 2011, crews added a dedicated right-turn lane to the northbound Ga. 400 off-ramp.

"Prior to this improvement, northbound congestion at the Windward Parkway and GA-400 interchange was notorious with more than 168,000 cars passing through the interchange each day," the CID said on its website.

For years, residents have said in surveys that they want some more mass transit connectivity to the Windward/Ga. 400 area, either through rapid buses or a rail extension.
