The five-station extension provides a direct train-to-plane connection for travelers taking public transportation to San Francisco International Airport.
"The SFO extension is a crowning achievement for the Bay Area," said BART Board Director James Fang. "The public has embraced this so much that the extension fares not only cover all of its operating expenses, it also makes money we can use to invest in other customer improvements and future BART extensions. We think this can serve as a model for other rail agencies."
Ridership on the extension continues to grow. Ridership has increased by 27 percent over the past four years and, in the past two years, it's grown at a rate of 10 percent.
The BART to SFO Extension is 8.7 miles long and consists of five stations: Colma, South San Francisco, San Bruno, San Francisco International Airport and Millbrae.
