Embarcadero is a BART and Muni Metro station in the Financial District of San Francisco. The easternmost stop on the Market Street Subway, Embarcadero acts as a major hub for passenger movement throughout the San Francisco Bay Area. With 45,460 exits each weekday in 2015, Embarcadero is the busiest station in the BART system, a title for which it vies with its western neighbor, Montgomery Street. It is the first stop in San Francisco for BART trains after crossing through the Transbay Tube from West Oakland. This station was an infill station, opening in May 1976, three years after the rest of this section of BART's system; it was the first infill station in the BART system.(Wikipedia)
