OAKLAND ALAMEDA ACCESS PROJECT
OAKLAND ALAMEDA ACCESS OVERVIEW
Providing Access and Connections
Bringing Benefits to Our Communities
The Oakland Alameda Access Project (OAAP) is more than a transportation upgrade—it's a long-term investment in our community's safety, equity, and connectivity. By enhancing safety, reducing congestion, and improving bike and pedestrian connectivity, the project is helping to improve how people move within and through Oakland and Alameda.
Project Benefits:
- Connectivity: Improves travel connection between Alameda & I-880 regional travel, and between Alameda & Downtown Oakland (bike, car, pedestrians);
- Reduced Traffic: Eases traffic congestion and cut-through traffic on neighborhood streets, and improves connection to I-880/ regional travel;
- Safety: Improves safety in communities heavily impacted by cut-through traffic, including in Chinatown, where more than 60 percent of Oakland's severe and fatal accidents occur;
- Bike & Pedestrians: Provides a new facility in Webster Tube & improves access in Posey Tube to better connect Oakland & Alameda; Safety & accessibility improvements at intersections, added sidewalks and bike facilities in Oakland & Alameda;
- Climate Equity: Reduces emissions in equity community experiencing air pollution/ high particulate matter exposure.

Project Resources
The story behind the Oakland Alameda Access Project—why it matters, how it came to be, and the people making it happen.
Why This Project Was Needed
Currently, drivers navigating between I-880, I-980, and the Webster and Posey Tubes must contend with congested city streets, which leads to bottlenecks, delays, and vehicle-pedestrian conflicts.
Project Beginnings
The I-880 Oakland Alameda Access Project (formerly called the I-880 Broadway-Jackson Project) is improving connectivity between I-880, I-980, and the cities of Oakland and Alameda.
Alameda CTC, the project sponsor, and Caltrans, the agency now leading construction, are working in partnership with the cities of Oakland and Alameda to deliver the project. It 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 improvements under construction do conflict with future plans within the corridor.
These improvements advance safety, provide direct travel routes for motorists traveling to or from the freeway and reduce freeway-bound traffic within heavily populated pedestrian neighborhoods like Chinatown. The work will deliver safe and accessible bicycle and pedestrian facilities that will provide improved connectivity for all travel modes between Downtown Oakland, Chinatown, the Jack London District and Alameda.
