Site work, paving and new construction of a bridge / tunnel in Alameda, California. Conceptual plans call for the construction of a bridge / tunnel; for site work for a bridge / tunnel; and for paving for a bridge / tunnel.

The City, in partnership with the City of Oakland, is advancing the implementation of a bicycle and pedestrian bridge to create high quality multi-modal access between Oakland's Jack London Square area and west Alameda. This project is the long-term crossing option identified in the 2009 Estuary Crossing Study. Currently, the only bicycle and pedestrian access is inside the Posey Tube, on a narrow three-foot wide walkway. Only approximately 100 people brave this crossing each day. A new bicycle and pedestrian bridge will provide a safe and convenient sustainable travel option between commercial districts, the downtown Oakland employment center, the many residents in both cities, and to and from the BART stations that connect people to the rest of the Bay Area region. This project will develop the Project Initiation Document (PID) in collaboration with the Alameda CTC. The PID will allow the bridge to become a fundable project by further defining potential build alternatives and landing locations on both sides of the estuary, preparing detailed cost estimates, outlining environmental and permitting requirements, exploring potential ownership and maintenance of the bridge, plus identifying any other major elements that should be investigated. Project is included in the City of Alameda's Capital Improvement Plan. As of April 23, 2025, per owner, they are still in early planning stages, with construction unfunded, and not expected before 2033. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
