Future plans 

Originally at full system implementation, Xpress had planned to operate 27 routes traversing 12 metro area counties. However, due to the popularity of its bus service (overcrowding on routes has become commonplace) the agency has already reached this goal. A second expansion phase is now being implemented to have 47 routes in operation by the 2013 fiscal year. These routes will connect the outlying suburbs with each other and downtown Atlanta. Though most routes go to downtown Atlanta, some routes terminate or make stops at MARTA train stations along the route.
