Dumbarton Transportation Corridor Study

Overview
SamTrans is conducting a transportation feasibility study of the Dumbarton Corridor to identify short- and long-term strategies that reduce traffic congestion and improve mobility between Alameda, San Mateo and Santa Clara counties. The study will examine potential solutions to address both congestion on the Dumbarton Bridge (Highway 84) and connecting roadways, as well as the rehabilitation and repurposing of the Dumbarton rail bridge to the south. As a feasibility study, the study will not approve any future projects, but will instead provide local stakeholders with options to consider developing further. The Corridor directly connects the cities of Newark, Fremont and Union City in the East Bay, and Redwood City, Menlo Park, East Palo Alto and Palo Alto on the Peninsula.

 

Study Purpose
The Dumbarton Transportation Corridor Study will recommend a phased program of operational and infrastructure improvements that enhance mobility between Alameda, San Mateo and Santa Clara counties. The Study will examine opportunities to improve auto, transit, bicycle, pedestrian, and other uses of the Dumbarton Bridge and Dumbarton rail bridge, including enhancements to Dumbarton Express Bus (DBX) commuter service. The study will also identify ways to enhance rail bridge safety on the Bay’s waterways and provide connectivity to commuter and intercity rail services by recommending options to preserve and repurpose the rail bridge.
Through connections to Capitol Corridor, Altamont Commuter Express, Amtrak and Caltrain, commuters from the South Bay could travel to destinations in the East Bay, Central Valley and beyond.

The study aims to also address regional and local mobility issues, including the jobs/housing imbalances in the southern Bay Area that threaten the economic vitality of jobs-rich areas that lack housing alternatives. It will also evaluate infrastructure improvements needed along the bridge approaches on each side of the Bay.

Study Management
SamTrans, as owner of the Dumbarton rail bridge and a member of the Dumbarton Bridge Regional Operations Consortium (DBROC) that oversees DBX service, will manage the study with two transportation authorities that support multi-modal improvements at each end of the Dumbarton bridges. These are the San Mateo County Transportation Authority and Alameda County Transportation Commission. Other project partners include AC Transit, which operates Line U from Fremont to Stanford University and administers the DBX service and Facebook, which brings financial support to the study as well as a private sector perspective on how transportation infrastructure can serve the needs of major employers.
