Regional Express Bus/Arterial Roads Program
In the spring of 2002, the Boards of Commissioners in Clayton, Coweta, Douglas, Henry, Cobb, DeKalb, Fulton, Gwinnett, Paulding and Rockdale counties all voted to participate in the GRTA Regional Express Bus System and Arterial Road Program.  A legal challenge to the bond program originally intended to fund the program delayed the project for approximately one year.  The Regional Express Bus and Arterial Roads program was reinvigorated in early summer of 2003.

GRTA will provide express bus service to each of the counties in exchange for a one-time payment toward the costs of the service.  Additionally, the counties have identified arterial road projects with a value approximately ten times that of the operating costs payment.  Using bond funds provided by the SRTA, GRTA will work with the counties, the ARC and the GDOT to build the projects.  Bus service on the first routes will begin in 2004.  Work on the arterial road projects will begin in the fall of 2003.
