Lemon Creek/Mendenhall Valley- The main route in the system, it serves three of the four primary populated places in the borough: Mendenhall Valley, Lemon Creek, and the city center of Juneau. In the west, the route makes a large loop through the Mendanhall Valley, serving the Mendenhall Mall, before travelling east along the older and more business lined Glacier Highway (as opposed to Eagan Drive, the bypass). While passing through the Lemon Creek area, it passes the Nugget Mall, Bartlett Regional Hospital, and various homes and business. It ends in the east with a narrow loop through central Juneau, passing various government buildings.
Express/University- This route offers quicker service to important locales, with more spaced out stops. In the west, it begins at the University of Alaska Southeast, then travels to Juneau International Airport and heads along Egan Drive to bypass most of Lemon Creek. It ends by making a short loop through the edge of Downtown Juneau.
Douglas- The fourth main population center of the borough is served by this route. It begins by making a narrow loop through Juneau's government corridor and downtown, before passing over the Juneau-Douglas Bridge and heading south along the Douglas Highway, ending at a loop where this road becomes St. Anne's Avenue.
