Project Description

The Northwest Corridor Project is an innovative project utilizing the collaborative resources of two key Georgia State agencies, Georgia Department of Transportation (GDOT) and Georgia Regional Transportation Authority (GRTA).  The two agencies have combined their own individual projects, the I-75/I-575 HOV Lanes Extension Project and the Northwest Connectivity Study, as a means to efficiently move through the federally required environmental process and expedite implementation.  The project has been identified by Governor Perdue?s Fast Forward transportation program as a top priority for the Atlanta region.

The proposed project currently under consideration provides for the extension of high occupancy vehicle (HOV) lanes on I-75 north from Akers Mill Road to north of Hickory Grove Road, construction of new HOV ramps and interchanges for access to the system, and implementation of express bus or bus rapid transit (BRT) services supported by transit stations, park-and-ride lots, and various bus priority improvements.  Additionally, HOV lanes are also proposed on I-575 from the I-75/I-575 Interchange to Sixes Road in Cherokee County.  Truck Only lanes (TOL) are also proposed for consideration on I-75.  The truck only lanes would be constructed within the same limits on I-75 as the HOV lanes and would be barrier separated from the general purpose and HOV lanes. The alternatives under consideration also include options for tolling the HOV and truck-only lanes. Study Area Map (.pdf)

GDOT has assumed the role of lead state agency in the preparation of the environmental studies, in cooperation with GRTA and the corresponding federal agencies, the Federal Highway Administration (FHWA) and the Federal Transit Administration (FTA).
