AMHERST, Mass. - Beginning March 24, University of Massachusetts Transit Services will provide expanded shuttle service on campus. As of that date, buses will run until 2:33 a.m. daily, instead of ending service at 1 a.m. as they do currently. In addition, a new campus shuttle will be added on Saturdays and Sundays, beginning at 5 p.m. and operating until 2:33 a.m. The shuttle utilizes full-sized, handicap-accessible buses that are radio and camera-equipped. There is no charge to UMass students for the bus service.
