Our Goal: build a bicycle and pedestrian moveable bridge connecting Alameda and Oakland.

There is a critical gap for bicyclists and pedestrians traveling between west Alameda and downtown Oakland. Travel is currently limited to the Posey Tube walkway which is too narrow to accommodate wheelchairs — let alone a steady flow of bikers and pedestrians. Anyone who has traveled the tube has not come out unscathed, due to the unavoidable walls caked with soot from car traffic (imagine what that exhaust is doing to your lungs!).

Since 2016, WOBO has been working alongside multiple organizations (including Bike East Bay and Bike Walk Alameda) to advocate for a new bridge. This bridge would provide 24x7x365, convenient, and enjoyable access for everyone. Benefits would include congestion relief for commuters, increased economic activity on both sides, increased equity for the nearby underserved community, reduced greenhouse gas emissions, and last but not least, a perfect opportunity to enjoy a leisurely bike ride or stroll over the estuary.

Bike Walk Alameda has been tackling this project since 2006 but the “Bridge the Gap” campaign was officially launched in May of 2016. Progress has been made including a positive feasible study, but we need your help to make this a reality.

Get Involved.

Our Goal: Update November 2025:

The Oakland-Alameda Estuary Bridge Project is moving ahead with its next phase: the Waterway Study. The Alameda City Council has authorized Moffatt & Nichol to conduct a grant-funded study. Over 20 months, this firm will collect data and make models to determine the dimensions of a potential bridge, as well as the parameters needed for US Coast Guard approval. 

The Caltrans District 4 Bike Plan Update also identified this project as a top-tier project in Alameda County! (see the chart below).
