The $514 million, 14 mile Dublin-Pleasanton BART extension was part of the first-phase $2.5 billion capital expansion program of the Bay Area Rapid Transit District. The Dublin-Pleasanton extension includes twelve cast-in-place, prestressed concrete box girder bridge; three precast, prestressed concrete bridges; two reinforced concrete bridges; one steel box girder bridge; one steel plate girder bridge; one cut-and-cover tunnel; and three planned stations. Due to budget constraints, only two stations, the Castro Valley Station and the East Dublin-Pleasanton Station, were built. This extension branches off from the existing Bayfair BART station in Hayward and occupies the median of I-580.
