GDOT Northwest Corridor Express Lanes

on this page

Situated northwest of downtown Atlanta, Interstates 75 and 575 connect the suburban cities of Marietta, Kennesaw, Acworth and several unincorporated communities in Cobb and Cherokee counties. Motorists couldn’t avoid the long travel times and heavy congestion along this busy corridor. After five years of construction, new, multi-award-winning express lanes opened, and rush hour commute times were cut in half as drivers’ speeds doubled. 

We provided owner’s construction engineering and inspection (OCEI) services for the Georgia Department of Transportation’s (GDOT) largest project ever, the Northwest Corridor Express Lanes Project. The project consisted of constructing nearly 30 miles of reversible tolled lanes along I-75 and I-575 and included six new express interchanges on I-75, as well as new access points and bridge improvements.

The project incorporated an inspection model, with the developer providing quality assurance CEI while we provided owner’s verification CEI, a first for a GDOT project. Working closely with our client, we developed several standard operating procedures for how the work was to be performed and incorporated the statistical analysis method, comparing the developer’s inspection and test results with our results. The new model proved to be a success and became GDOT’s standard practice for its Major Mobility Investment Program (MMIP) projects.  

The Northwest Corridor Express Lanes Project has received numerous awards including: 

  • Design-Build Institute of America (DBIA) 2019 Award of Excellence – Transportation Category
  • American Council of Engineering Companies (ACEC) Georgia 2018 Engineering Excellence Awards, State Award
  • AASHTO 2019 American Transportation People’s Choice Award
  • 2019 Construction Management Association of America’s (CMAA) Project Achievement Award, Transportation project with a Construction Value Greater Than $50 Million
  • International Road Federation (IRF) 2019 Project Award, Program Management Category
  • Named the No. 1 Project on Roads & Bridges Magazine’s Top 10 Roads list in 2018
