Major work begins on one of metro Atlanta’s worst traffic bottlenecks

News

I-285/SR 400 road improvements begin
The new I-285/SR 400 interchange is the first piece of the puzzle for traffic relief. In the years to come metro-Atlantans will soon notice their commutes improve.Key improvements to the I-285/SR 400 Interchange Reconstruction project in Atlanta, Georgia, USA include collector-distributor lanes along 4.3 miles of I-285 and 6.2 miles of collector-distributor lanes on SR 400. The collector-distributor lanes will connect through a series of flyover ramps creating a new interchange connecting the major interstate bypass and major state route.Made by Ferrovial Agroman US Corp for State Road Tollway Authority, the interchange connects nearly 100,000 residents and an additional 123,000 employees to home, shopping or work at one of the 5,000 companies located in the north metro Atlanta region.The I-285/SR 400 Interchange Reconstruction project also encompasses smaller key projects that will help improve traffic conditions for the busy metro region. One of the improvements includes expanding and lengthening Mount Vernon Highway bridge over SR 400 and constructing a diverging-diamond interchange on Abernathy Road at SR 400.Upon its completion in summer 2020 the interchange reconstruction project and its smaller projects will bring some relief for the 420,000 vehicles that use the interchange daily. The full impact of the project won't be felt for more than a decade.The reason, the I-285/SR 400 Interchange Reconstruction project sits at the center of future express toll lanes planned by the Georgia Department of Transportation. The state DOT plans to build express toll lanes on I-285 and SR 400. These improvements will help relieve traffic on the major corridors allowing motorists to travel a minimum of 45 miles-per-hour during peak travel times. The express lanes will free up space on the general purpose lanes for drivers who chose not to use the express toll lanes.To learn more about Ferrovial's construction line, click here.
