The department also operates the public transit system called Cambus, a 32-bus intracampus transit system that provides fixed-route shuttle service throughout the main campus as well as a connection with the Oakdale campus. Cambus services do not require a boarding fare or pass, and are available to the general public. Cambus also provides a demand-response transportation service, the Bionic Bus, for qualifying persons with disabilities. In addition, special transportation services are provided for many University activities, including athletic events and orientation. All vehicles are accessible to persons with disabilities. The Cambus Office is located on Stadium Drive immediately west of Kinnick Stadium.
