East Colfax Bus Rapid Transit (BRT)

Bus-Only Lane Operations (BOLO)

Beginning Sept. 27, RTD’s Route 15 and 15L buses will use the center bus-only lanes and stations along Phase 1 of the East Colfax Bus Rapid Transit (BRT) Project between Broadway and Colorado Boulevard, in alignment with RTD’s September Service Changes.

Under BOLO, Routes 15 and 15L will use the bus-only lanes and customers will board at the center platforms between Pennsylvania Street and Colorado Boulevard with level boarding, bus lanes, interior bike racks, and platform security measures, including cameras and emergency telephones.

The stations are spaced about three to four blocks apart and are identifiable by the white arches and canopies in the center of Colfax Avenue. Find the station closest to you ici.

Overview of the E. Colfax Bus Rapid Transit project

Le East Colfax Avenue Bus Rapid Transit (BRT) project, led by the City & County of Denver, with RTD and the City of Aurora as partners, delivers 8.5 miles of BRT to East Colfax Avenue between Broadway and I-225. The section within Denver that is between Broadway and Yosemite Street will be center-running, dedicated lane BRT with level boarding in the middle of Colfax Avenue. As the project transitions to Aurora, the improvements switch to the outside lanes of Colfax Avenue with side-running stations in mixed traffic and level boarding at select stations.
