O.co Coliseum, originally Oakland–Alameda County Coliseum and commonly known as the Oakland Coliseum, is a multi-purpose stadium in Oakland, California, United States, which is home to both the Oakland Athletics of Major League Baseball (MLB) and the Oakland Raiders of the National Football League (NFL). It opened in 1966 and is the only remaining stadium in the United States that is shared by professional football and baseball teams. The Coliseum was also home to some games of the San Jose Earthquakes of Major League Soccer in 2008–2009 and hosted games at the 2009 CONCACAF Gold Cup.
The Coliseum has 6,300 club seats, 2,700 of which are available for Athletics games, 143 luxury suites, 125 of which are available for Athletics games, and a variable seating capacity of 35,067 for baseball, 56,057 for football and 63,132 for soccer. In seating capacity, O.co Coliseum is the smallest NFL stadium, and the 2nd smallest MLB stadium.
The Oakland–Alameda County Coliseum complex consists of the stadium and the neighboring Oracle Arena.
Oakland Coliseum is a complex of three stations of two public transit providers that are within 600 feet (180 m) of each other: Amtrak Capitol Corridor's Oakland Coliseum station, Bay Area Rapid Transit (BART)'s Coliseum station, and the BART to Oakland International Airport automated guideway transit (AGT) terminal. They are located in East Oakland, and are connected to each other, and to the O.co Coliseum and the Oracle Arena by pedestrian bridges. BART and Capitol Corridor Joint Powers Authority (CCJPA), Capitol Corridor's administration agency, will sometimes refer to these separate stations as one station.
In addition to the Coliseum–Oakland International Airport AGT line, AC Transit bus routes 73 (73rd Avenue) and 805 (All-Nighter) also provide service between the BART station and Oakland International Airport.
BART's Coliseum station consists of an elevated island platform with the concourse mezzanine at ground level. The BART to OAK Airport station has a single track and side platform.
