The idea for Prince George's County establishing its own transit system was initially brought up by Prince George's County in 1986, as a way of providing better transportation access to the Upper Marlboro Courthouse and other important government offices, that were isolated from many of the other areas of Prince George's County that were served by WMATA's Metrorail and Metrobus System.

Route 20 would operate between the Addison Road Metro Station (WMATA's Blue Line's northern terminus in Prince George's County at the time, prior to the Largo Town Center extension in December 2004) and the Upper Marlboro Courthouse.

Route 21, on the other hand, would operate between the New Carrollton Metro Station (WMATA's Orange Line's northern terminus in Prince George's County) and the Equestrian Center, also serving the Upper Marlboro Courthouse as well.

The Bus system was able to increase the number of routes it operated around this time as WMATA's northern Green Line stations in Prince George's County, which notably were the West Hyattsville, Prince George's Plaza, College Park U of MD, and Greenbelt opened about three years earlier in December, 1993.
