It not only shows the BART system, including the newly opened Berryessa/North San Jose Station, but also other connecting public transit systems, such as San Francisco Muni and the Santa Clara Valley Transportation Authority. On some signs, this is written as San Francisco/Pts Baypoint or SF BAY PT. The current BART map is an enhancement from a design originating around 2010/2011. To deal with the wet, muddy environment beneath San Francisco's busy Market Street, crews did their excavation work entirely under compressed-air conditions. To get to downtown San Francisco, go down the escalator from the ticketing area and take the Pittsburg/Bay Point train. Found artifactsĮxperts grappled with a high water table, seismic considerations, buried ships and other artifacts, and a tangle of underground utilities-many of them uncharted, owing to their installation during the course of the previous century building the tunnels and cavernous stations below Market Street in downtown San Francisco. We later served as general engineering consultant for a $1.5 billion seismic retrofit program.
Our continued roleīechtel continued its role with BART as general engineering consultant on a $2.7 billion extension program in four different counties, including service to and from San Francisco International Airport. BART now operates nearly 700 revenue-producing vehicles. Growing railwayīechtel delivered more than 70 miles (115 kilometers) of wide-gauge, double-track, ballast-free, fully automated electric railway-which later extended to 104 miles (167 kilometers). The original system proved so effective that the length of BART railway has grown by nearly 50 percent. The project also included a hard-rock tunnel through the Berkeley hills. The BART project's most dramatic feat, the Transbay Tube, a submerged tube across San Francisco Bay, was completed in 1969. Crews made watertight connections between the sections, removed the end caps, and secured the entire tube. The project team constructed the 3.6-mile- (5.8-kilometer-) long underwater passage in 57 sections. Fabricated above ground, the concrete-and-steel modules were floated into place, immersed-with their ends sealed-into a trench spanning the bottom of San Francisco Bay, between San Francisco and Oakland. The plans were approved in 1962 and the joint venture was given the green light to perform detailed engineering and manage construction. The Bay Area Rapid Transit District asked a Bechtel joint venture to develop engineering data, a preliminary design, and estimates for a radically new rapid-transit system.
