With the help of a federal grant, big changes are coming to Cambus that will help the University of Iowa meet sustainability goals and increase the bus system’s efficiency. The Federal Transit Administration awarded the University of Iowa a $16.4 million grant for improvements to the Cambus system, including the purchase of six new battery-electric buses that will help the UI reach its sustainability goals. In addition, the funds will help provide updates to the Cambus Maintenance Facility.
