Capital Transit System

The Capital Transit System is the public transportation agency that serves the City and Borough of Juneau, Alaska. Owned by the municipality, it operates eight bus routes - three of which are labeled as the "Core Service" and run seven days a week (from 6am to 11pm Monday-Saturday & 9am to 6pm on Sundays) with the remaining five running as limited weekday connector. express, or commuter services. Although CTS previously operated routes that offered complete flag stop service along their entire route, routing changes that took place in November 2022 coinciding with the opening of the Mendenhall Valley Transit Center eliminated those routes. In areas where there are no signed bus stops, patrons can still flag down the bus in any location where it is safe for the bus to pull over.

Core Service
Core Service routes operate seven days a week with reduced service on weekends and holidays.
 * 1 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 west over the Juneau-Douglas Bridge and heading south along the Douglas Highway, ending where 3rd Street turns into St. Anns before looping around at Savikko Park/Sandy Beach.
 * 3 Mendenhall Valley Counterclockwise: This route 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 counterclockwise loop through the Mendenhall Valley, serving the Mendenhall Valley Transit Center (located at 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 Gastineau Humane Society, the Juneau Police Department, Bartlett Regional Hospital, and various homes and business. It ends in the east with a narrow loop through central Juneau, passing various government buildings.
 * 4 Mendenhall Valley Clockwise: Follows the same route as route 3, but instead does a clockwise loop around Mendenhall.
