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: Improvements to accommodate bus movements without stopping at the toll plaza. Other improvements include the activation of the metering lights to better manage traffic downstream of the toll plaza.
- Traffic Signal Improvements: Bayfront Expressway intersection improvements, including transit signal priority, bus queue jump lanes and an adaptive traffic signal system to reduce delays at the signals.
- SR-84 Off-Ramp Improvements: Eastbound SR 84 / Thornton Avenue off-ramp reconfiguration to accommodate an additional left-turn lane for added capacity and vehicle storage.
- Transit Improvements: 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.
