Oakland Alameda Estuary Bridge Project Update (Discussion)

To: Honorable Chair and Members of the Transportation Commission


The City of Alameda (City), in close partnership with the City of Oakland, is moving forward with the next phase of planning and design work for the Oakland Alameda Estuary Bridge (Bridge), called a Project Initiation Document (PID). This new bicycle and pedestrian connection is over 15 years in the making. Once fully designed, funded and constructed, the Bridge will provide an alternative to the substandard and deficient Posey Tube path and connect west Alameda and Jack London Square, Amtrak, Downtown Oakland, two nearby Oakland BART stations and many more destinations (see Fact Sheet in Exhibit 1). It will be a free crossing, above ground, anticipated to have over 5,000 crossings a day, and is expected to eliminate 40,000 motor vehicle trips that traverse through equity priority communities in Oakland.

This planning effort was the first to directly analyze the feasibility of new or improved Estuary crossings, with the goal of developing crossing options that would appeal to users, adjacent communities, decision-makers, transit providers and funding authorities. Seventeen (17) different crossing options were studied, including a gondola, different bridge types, Posey/Webster Tubes enhancements, water shuttle services and a new transit tube. Solutions for the near-, mid-, and long-term were explored. The top recommended, long-term option was determined to be a moveable bicycle-pedestrian bridge.

In 2016, the City Council (Council) directed that staff begin working on the bridge project and ...
