Georgia 400 express lane project: What drivers need to know about closures this week

There’s a major update for your morning commute as construction work gets underway for the Georgia 400 toll lane project.

The $4.6 billion project will add two express lanes in each direction on Georgia 400, beginning at the MARTA North Springs Station and ending just north of McFarland Parkway in Forsyth County.

“I drive down 400 a lot,” said Tracy Crawford, who is no stranger to Georgia 400. “Traffic is really really bad going one way or the other.”

Crawford learned Sunday that lane closures begin Monday for the toll lane construction project that is expected to take five years.

“You’re going to very upset people,” she said.

Workers have spent the last few months clearing away trees in preparation for the project. Heavy construction is set to begin this month and be completed in 2031, at the earliest.

Officials said the project’s goal is to ease congestion. But some question if the additional lanes will make a difference.
