The Georgia Department of Transportation will hold a series of meetings on upcoming express lanes on Ga. 400, including a meeting in Forsyth County.

Meetings will be held at Hilton Garden in Alpharetta on Feb. 28; at the Forsyth Conference Center on March 5, at the DoubleTree in Roswell on March 7 and at City Springs in Sandy Springs and on March 12.

Last year, the project received $184 million in Infrastructure for Rebuilding America, or INFRA, grant funding to add two express lanes on each side of Ga. 400 from the North Springs Marta Station in Sandy Springs to McGinnis Ferry Road and one express lane in each direction from McGinnis Ferry to McFarland Parkway.

Express lanes are optional toll lanes along existing lanes aimed at allowing drivers to bypass congestion.

Construction for the express lanes is slated to begin in 2021 and be completed by 2024.

The lanes are not planned to reduce the number of normal lanes on the road, including new lanes funded through a $200 million transportation bond approved by voters in 2014.

According to GDOT, the new lanes will add 65 miles of road and reduce traffic delays by 18 percent.

Once other projects are completed, the new Ga. 400 lanes will tie in with express lanes on I-285 between I-75 and I-85.

The projects are one of 11 Major Mobility Investment program projects from around the state. The projects include interstate widenings for options of I-85 and I-16, commercial vehicle lanes on I-75 near Macon and interchange reconstruction projects on I-16 and I-285.

The projects total $11 billion.
