Northwest Corridor Express Lanes

Opened September 8, 2018, the Northwest Corridor Express Lanes extend along I-75 and I-575 in Cobb and Cherokee counties and include 29.7 miles of tolled reversible express lanes.

Construction for the NWC Express Lanes project began in November 2013 and took approximately five years to complete. It represents the largest, single investment in Georgia’s transportation infrastructure, one of the most transformative projects in state history and the most innovative express lanes project in the country. HNTB provided P3 project management services to the Georgia Department of Transportation for the project, serving as the PMC for its Office of Innovative Delivery.

The project has been recognized with several prestigious awards:

  • National Award of Merit (Transportation) by the Design-Build Institute of America
  • State award in the “Large Project-Overall” category by the American Society of Civil Engineers
  • No. 1 project on the 2018 Roads & Bridges Top 10 Roads list

The express lanes have seen 7+ million users over 12 months and rush hour cut by one hour during morning and evening commutes.
