network in 2011. The FBO is centrally located at OAK's North Field in the Hangar 5 facility. Landmark has initiated a multimillion-dollar renovation project, having already upgraded the FBO terminal along with beginning hangar and property improvements. KaiserAir also provides FBO services at Oakland's North Field, performing maintenance on Gulfstream, Hawker, Cessna and other business jet aircraft. KaiserAir operates Kona Shuttle with flights to Hawaii and charter business jets. Ground transportation Oakland International Airport is accessible from Interstate 880 (Nimitz Freeway) which is away. The airport can be reached by exiting Hegenberger Road or 98th Avenue heading west; both streets converge into Airport Road before looping around in front of the terminals. Doolittle Drive (State Route 61) crosses both Hegenberger Road and 98th Avenue just to the east of where they converge into Airport Road, providing access to the city of Alameda. Bay Area Rapid Transit (BART) serves the airport via Oakland International Airport station. The station is served by the Beige Line, an automated guideway transit (AGT) route that connects the airport with Coliseum station. The AGT vehicles depart from the airport and Coliseum station every five minutes during daily peak hours and are designed to transport travelers to and from the airport in about eight minutes with an on-time performance of more than 99 percent. A fare surcharge is added for trips to or from Oakland International Airport. The Oakland Airport Connector Project is largely attributable to the work of former BART director and port commissioner Carole Ward Allen who was responsible for securing local, state, and federal funding for the project. Ward Allen advocated for its approval before several transportation authorities endorsed the project, which created between 2,500 and 5,200 direct and indirect jobs. Some critics of the project argued that the money would be better spent on supporting existing local transit agencies, which had financial issues at the time. There are three AC Transit routes that serve Oakland Airport, one route runs during the daytime and early evenings, one route runs at all times, and the last route runs overnights as a part of the Bay Area's All Nighter bus network: Route 21 provides daytime and early evening service from the airport to the Dimond District via Bay Farm Island, Alameda, and Fruitvale, making a limited connection with the Alameda Harbor Bay Ferry at Bay Farm Island, and a full-time connection with BART at Fruitvale station.
