The 3.2-mile Oakland Airport Connector (OAC) project was a Design/Build effort, consisting of an automated guideway system (people mover) direct cable pull, to connect the Coliseum/Oakland Airport BART Station to the Oakland International Airport terminal. The project included an elevated guideway, a cut-and-cover tunnel section, and an at-grade section. In addition to the guideway, the project consisted of a pedestrian bridge, two stations and a maintenance and storage facility. The OAC project involved multiple public jurisdictions, including the City of Oakland, BART, Caltrans, and the Port of Oakland.
