Facebook will fund a $1 million study by the San Mateo County Transit District to explore potential improvements to the Dumbarton corridor, SamTrans announced Jan. 6.
The study will cost $1 million and will focus on exploring improvements to the State route 84/Dumbarton Bridge, the Dumbarton rail corridor, and arterial and highway networks that connect to the bridge.
SamTrans said the project will analyze the corridor between Alameda and San Mateo counties, including the impact on the cities of Menlo Park, Redwood City, East Palo Alto, Newark, Union City and Fremont.
Facebook will offer funding necessary to study rail corridor alternatives, an analysis that was put on hold in 2014, the announcement said.
The Dumbarton rail corridor was purchased by the San Mateo County Transportation Authority (TA) in 1994. Plans to transform the original rail bridge into a commuter rail line by 2012 were derailed in 2008 when $91 million of funding intended for the transbay project was reallocated to BART to extend its East Bay route southward to Warm Springs in Fremont.
Currently, the Dumbarton Express, a bus administered by AC Transit on the East Bay, is the sole public transportation option to cross the bridge between the East Bay and the Peninsula.
