Project Profiles

The Northwest Corridor project, formerly known as West by Northwest Corridor project, extends along 29.7 miles of I-75 and I-575 and includes the following components:

• The extension of managed lanes from the current end of the HOV lanes along I-75 at Akers Mill Road south of I-285
• Two reversible tolled managed lanes to the west of the existing general purpose lanes along I-75 between I-285 north and I-575
• One reversible tolled managed lane in the median along I-75 between I-575 and Hickory Grove Road and along I-575 to Sixes Road

The design-builder will be responsible for design and construction of the road, including tolling ITS, signage, and integration of components, and will also be required to finance 10–20 percent of the cost of the project.

GDOT will be responsible for managing the procurement process and overseeing the design and construction of the facility. GDOT will also be responsible for the long-term operation and maintenance of the highway. Georgia State Road and Toll Authority (SRTA) will be responsible for the tolling operations, tolling gantries and equipment and for communicating with customers about tolls.
