Project Details

The I-880 Oakland Alameda Access Project (formerly called the I-880 Broadway-Jackson Project) proposes to improve connectivity between I-880, I-980 and the cities of Oakland and Alameda.

Alameda CTC, the project sponsor, and Caltrans, the lead for California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) requirements, are working in partnership with the cities of Oakland and Alameda to plan, identify and analyze potential freeway access and local roadway improvements between I-880, I-980 and the Posey/Webster Tubes connecting the two cities. The project is being coordinated with multiple corridor planning efforts and local and regional developments including but not limited to the Downtown Oakland Specific Plan to make sure that any multi-modal improvements identified will not conflict with future plans within the corridor.

These proposed improvements will provide direct travel routes for motorists traveling to or from the freeway to their desired location. The project will reduce freeway-bound traffic within heavily populated pedestrian neighborhoods like Chinatown and construct safe and accessible bicycle and pedestrian facilities that will provide improved connectivity for all modes between Downtown Oakland, Chinatown, the Jack London District and Alameda.

The Final Environmental Document (FED) for the Oakland Alameda Access Project has been approved. The full FED including appendices is available on the Resources tab.
