In the early 2000s the passenger buses used were refurbished by AC Transit. Bear Transit connects various areas of the university, including student housing, the main campus, the Hill area, Downtown Berkeley (including Berkeley BART), and distant locations such as Lawrence Hall of Science in the East Bay Hills and the Clark Kerr Campus south of the main campus. It also provides shuttle service to the Richmond Field Station (RFS), a research facility also owned by the University, located in Richmond.
