GDOT Northwest Corridor Transportation Improvements



2450 Commerce Avenue Suite 100
Duluth, GA 30096-8910

The Northwest Corridor Express lanes project entails two new lanes built to the west of the existing lanes along I-75 from I-285 to I-575. From that interchange, one new express lane added along I-75 north to Hickory Grove Road and one new express lane added along I-575 from I-75 to Sixes Road.

The lanes will be managed by dynamic priced tolling, allowing drivers to choose to pay a toll to bypass congestion. To maximize benefit for all travelers of the corridor, these express lanes will be reversible. The project will improve traffic flow, increase options for motorists and individuals using transit and registered vanpools and provide reliable trip times cutting commute times by up to 43 minutes.

The MA team included project liaison manager, CEI manager, lead office engineer, 4 office engineers, 4 project engineers, 3 ATMS/traffic signal engineers, 4 bridge inspectors, 8 senior inspectors, 20 inspectors, materials testing manager, lab manager, and 6 testing technicians.
