Routes and servicesEdit

CUE operates two loop routes between George Mason University and the Vienna Metro station, each running in both directions for a total of four named routes. The Green loop, consisting of routes Green 1 (clockwise) and Green 2 (counterclockwise) operates on the east side of Fairfax, while the Gold loop, consisting of routes Gold 1 (clockwise) and Gold 2 (counterclockwise) operates on the west side.

In addition to providing service to GMU and Vienna Metro, the CUE serves all major activity centers in the City of Fairfax, including downtown, Kamp Washington, Old Town Fairfax, Fairfax Circle and Fair City Mall.

In 2009, the City of Fairfax partnered with Montgomery County, Maryland, in the purchase of new buses. As a result, six 35-foot, low-floor Gillig Hybrid buses were added to the fleet in August 2009. These new buses are expected to consume much less fuel, as they operate off an electric engine when operated at 35 MPH or lower, and 35 MPH is the maximum speed limit in Fairfax.[5] The CUE Bus system owns and operates twelve additional 35-foot, low-floor Gillig clean diesel buses in its fleet, half of which replaced the remaining 30-foot Gillig Phantom buses in the fall of 2015, the other half entered service in May of 2022.
