Update
The Dumbarton Forward initiative will implement a suite of near-term operational and multimodal strategies to address traffic flow, congestion and person-throughput in the State Route (SR) 84 - Dumbarton Bridge - Bayfront Expressway Corridor between I-880 in Fremont and Marsh Road in Menlo Park. The proposed improvements support modes of travel other than single-occupancy vehicles, including strategies to encourage transit use. The specific components of the Dumbarton Forward initiative include:
- Part-time bus-only lane (a multi-year pilot) to allow authorized bus operators to bypass peak period congestion, resulting in improved transit reliability
- Dumbarton Bridge Toll Plaza operational improvements to accommodate bus movements without stopping at the toll plaza
- Bayfront Expressway intersection improvements, including transit signal priority, bus queue jump lanes and an adaptive traffic signal system to reduce delays at the signals
- Eastbound SR 84 / Thornton Avenue off-ramp reconfiguration to accommodate an additional left-turn lane for added capacity and vehicle storage
- Relocation of Ardenwood Park-and-Ride bus stops to a location closer to the SR 84 on-ramps for easier access for buses
Part-time bus-only lane goals:
- Move more people in fewer cars
- Offer travel time savings that can incentivize mode shift to buses
- Support public and private express bus and shuttle operations
- Connect regional employment centers and transit hubs
