Dumbarton Forward is a set of near-term strategies to improve efficiency and reduce delays on and near the Dumbarton Bridge.
Dumbarton Forward aims to limit traffic congestion during peak periods in the State Route 84-Dumbarton Bridge-Bayfront Expressway corridor between Interstate 880 in Fremont and Marsh Road in Menlo Park.
Dumbarton Forward encourages commuters to use transit instead of driving in personal vehicles, which improves commute times for all travelers in the area.
Dumbarton Forward Strategies
Part-Time Bus-Only Lane
A multi-year pilot to allow authorized bus operators to bypass peak period congestion, resulting in improved transit reliability.
Traffic Signal Improvements
Bayfront Expressway intersection improvements, including transit signal priority, dedicated bus signals and an adaptive traffic signal system to reduce delays at the intersections.
Improve bus service on transbay routes - AC Transit, Stanford and Union City Transit.
Bike Access Improvements
To improve safety and connectivity for bicyclists, these improvements focus on completing critical gaps in existing bicycle networks along the corridor.
