Bay Area Rapid Transit (BART) is a public transportation metro system serving the San Francisco Bay Area in California. The rapid transit elevated and subway system connects San Francisco with cities in Alameda, Contra Costa, and San Mateo counties. BART operates 5 routes on 104 miles (167 km) of track connecting 45 stations, plus a 3.2-mile (5.1 km) automated guideway transit line to the Oakland International Airport which adds an additional station. A spur line in eastern Contra Costa County will utilize other rail technologies. With an average of 433,000 weekday passengers and 128.5 million annual passengers in fiscal year 2016, BART is the fifth-busiest heavy rail rapid transit system in the United States. The system's acronym is pronounced "Bart," like the name, and not as a spelled-out initialism (i.e., "B-A-R-T").
BART is operated by the San Francisco Bay Area Rapid Transit District, formed in 1957. As of 2017[update], it is being expanded to San Jose with the contiguous Warm Springs and Silicon Valley BART extensions.
