The Transbay Joint Powers Authority (TJPA) has primary jurisdiction with respect to all matters concerning the financing, design, development, construction, and operation of the Transbay Program. The TJPA is a joint exercise of powers authority created by the City and County of San Francisco, the Alameda-Contra Costa Transit District, the Peninsula Corridor Joint Powers Board, the California High Speed Rail Authority, and Caltrans (ex officio). The TJPA is managed by TJPA staff and is overseen by an eight-member Board of Directors.
