Bay Crossings Study
San Francisco Bay Crossings Study
In 2000, MTC launched a new San Francisco Bay Crossings study to update the 1991 Bay Crossings Study and address the dramatic increases in Bay Area population and traffic, and other changes that had occurred in the past nine years affecting transbay travel. Recent traffic projections, for example, show traffic volumes by 2010 are expected to be 50 percent higher on the San Mateo Bridge and 36 percent higher on the Dumbarton Bridge than estimated in 1991. Population and job growth also have exceeded expectations, particularly in Santa Clara Valley, which is expected to add 27 percent of all new jobs in the region from 1995 to 2020.
After more than a year of careful study, MTC adopted recommendations for a strategy to not only ease the congestion plaguing various routes across San Francisco Bay but to help deal with a 40 percent projected overall increase in transbay travel by 2025. Responding to a request by U.S. Senator Dianne Feinstein that a 1991 study be updated, MTC launched the San Francisco Bay Crossings Study in late 2000 and began analyzing the costs, travel impacts, and environmental issues associated with a long list of options for the three primary transbay corridors: San Francisco-Oakland, San Mateo-Hayward and the Dumbarton Bridge corridors. Study alternatives addressed expanded express bus service, highway operational improvements and carpool lanes, improved and new auto and rail crossings, and improvements to roadways approaching existing bridges.
A 13-member policy committee of MTC commissioners from Alameda, Contra Costa, San Francisco, Santa Clara and San Mateo counties, the Bay Conservation and Development Commission (BCDC), and Caltrans, plus transportation agency representatives, provided policy guidance. A technical advisory committee of staff from these agencies provided technical oversight. The study was funded by state funds and got underway in early 2001.
