Northwest Corridor Project

The I-75/I-575 Managed Lanes Extension Project, also known as the Northwest Corridor Project, is studying the addition of a managed lane system on I-75 north from Akers Mill Road to north of Hickory Grove Road and on I-575 from the I-75/I-575 Interchange to Sixes Road in Cherokee County.

The original Northwest Corridor Project proposed the addition of eight single-direction High Occupancy Vehicle (HOV) lanes and truck only lanes, two in each direction, on I-75 with one HOV lane in each direction on I-575. Through GDOT’s partnership with Georgia Regional Transportation Authority, Bus Rapid Transit (BRT) was proposed to operate in the HOV lanes. Construction of associated park and ride lots and BRT stations were also included as part of the project.

In May 2007, a Draft Environmental Impact Assessment (DEIS) was completed on the alternatives. Public comment revealed stakeholders’ concerns of the project’s size and scope, potential environmental impacts, and financial feasibility. As a result of the comments and the State’s funding capabilities, the truck only lanes and BRT components were removed from the project. The revised alternatives provide a reduced footprint resulting in reduced costs and fewer impacts.

Continuing to follow the National Environmental Policy Act process (NEPA), the project team has developed a Supplemental Draft EIS analyzing the new alternatives. Approval of the supplemental draft document is anticipated in late summer, with public hearing open houses tentatively planned for fall 2010.

In November 2009, GDOT announced that its partnership with the Georgia Transportation Partners, the private developer consortium who submitted a Public Private Initiative (PPI) on the project, was dissolved. New bids will be sought as GDOT moves forward with its larger, holistic toll-lane program for the state under the Public Private Partnership program. Please see the GDOT’s P3 website for more information on the program.
