Abstract:
Describes design and construction of the San Francisco Bay Area Rapid Transit (BART) system, constructed between 1959 and 1976. Innovations in seismic design from the BART system are still in use today. The system includes aerial structures, cut-and-cover structures, tunnels, and the Trans-Bay Tube, the longest and deepest underwater crossing of its type. The system has provided safe, reliable, and economical transportation throughout its history, including during the 1989 Loma Prieta Earthquake.
