Oakland Alameda Access Project

Project Overview

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 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 on the proposed 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.

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.

Today, motorists traveling between the I-880 and I-980freeways and the Webster and Posey Tubes, which connect the cities of Oakland and Alameda, must travel along congested city streets causing heavy bottlenecks, long delays and vehicle-pedestrian bicycle conflicts.

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.

After an extensive planning and community process, an alternative that best meets the project's purpose and need was selected. This alternative has been documented in the Final Environmental Document and is being carried into the final design phase, which commenced in February 2022.

The Project is currently in the bidding process.

Project Need

• Access between the freeway and the roadway networks between I -880 and the Tubes is limited and indirect and access to/from the cities of Oakland and Alameda is circuitous.
• Oakland Chinatown has a high volume of pedestrian activity and experiences substantial vehicle-pedestrian conflicts.
• The I -880 viaduct limits bicycle and pedestrian connectivity between downtown Oakland and the Jack London District.

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.
