Oct. 30, Thursday -- Unitrans -- the student-run bus service that has helped move UC Davis and the city of Davis for 40 years -- is inviting its passengers and other fans to celebrate two milestones: the dedication of a new terminal on campus and its 50 millionth rider. The new terminal, located north of the Silo on Hutchison Drive, opened in late September as a transit center for Unitrans, the shuttle to the UC Davis Medical Center in Sacramento, Yolobus and Fairfield Transit. It offers convenience for passengers transferring between lines and, with off-street bus parking and passenger loading, increases safety in the area. The $1.5 million project, supported by more than $1 million in grants from the Federal Transit Administration as well as undergraduate student fees, includes a new sidewalk; benches, bike racks, and passenger shelters will be added later. During the 2 p.m. ceremony, the bus service will honor its 50 millionth rider. Symbolized by its double-deckers, Unitrans operates more than 40 modern buses on 14 routes in Davis and has more than 3 million riders annually. Another bus terminal is located north of the Memorial Union Building.
