Oakland - Alameda Access Project
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 Alameda and Oakland.
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 Specific Plan and Bicycle Master Plan to make sure that any improvements identified for local roads will not conflict with future plans within the corridor.
WHY IS THIS PROJECT NEEDED?
The project will reduce traffic congestion on local roadways and improve overall corridor mobility and connectivity for motorists, bicyclists and pedestrians by addressing the following transportation challenges:
- Congested city streets with long travel delays
- Indirect routes to access the freeway
- Operationally deficient intersections
- Heavy vehicle traffic within active pedestrian neighborhoods (especially around Chinatown)
- Lack of pedestrian and bicycle connectivity
- Physical and visual barrier of I-880 overhead freeway structure
HOW WILL THE PROJET SOLVE THESE CHALLENGES?
The proposed project includes multiple types of improvements throughout the corridor such as:
- Reconstructing intersections and freeway ramps
- Removing the northbound Broadway off-ramp to narrow the barrier effect of the overhead structure
- Enhancing local roads and sidewalks
- Constructing wider multi-use bike paths 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 create connected, safe and accessible paths for pedestrians and bicyclists.
Here are videos showing the proposed project elements:
PROPOSED PROJECT IMPROVEMENTS
- Remove Broadway off-ramp and connect 6th Street from Oak Street to Broadway
- Upgrade Oak Street off-ramp
- Construct right turn from Posey Tube onto 5th Street
- Construct “horseshoe” loop under I-880 at Jackson Street to access northbound I-880
- Reconstruct southbound I-880/Jackson Street off-ramp
- Reconstruct 6th Street between Oak and Webster Streets
- Enhance Harrison/7th and Jackson/7th intersections for pedestrians
- Construct multi-use path connection from Posey Tube to 6th Street and downtown Oakland
- Construct bike lanes and multi-use path along 6th Street from Oak to Washington Streets
- Enhance sidewalks, bike/ped connectivity within project area
By connecting 6th Street between Oak Street and Broadway the project will:
- Increase connectivity for motorists, pedestrians and bicyclists for eight city blocks
- Enhance visibility for bikes and pedestrians at both Posey and Webster Tubes
- Improve access from the south to the Chinese Garden Park and enhance park experience by adding lighting or bench amenities
- Create opportunities to re-connect areas under the freeway to adjacent neighborhoods and re-invent public spaces
- Promote possibilities for gateway/identity features for Chinatown, Jack London Square and downtown

PROJECT COST AND FUNDING
The project team has been working diligently to gather and analyze project information, seek stakeholder concerns and review potential concepts that will address the current challenges. A proposed project has been identified to meet the current and future needs of the growing community. Efforts to-date include:
- Data collection
- Traffic analysis
- Stakeholder engagement
- Concept development
The proposed project is moving forward into the environmental process which began in September 2017. A successful public scoping meeting was held on Thursday, September 28. Approximately 100 community members attended and reviewed information, watched the information video, talked with team members and provided comments. All meeting information can be found online. The public comment period ended October 31, 2017.
There are a number of opportunities for the public to get involved in this important project. The milestones (see chart above) identify project design, environmental work and public engagement opportunities during the environmental review process.
The project team is proactively meeting with area and regional stakeholders to gather input and address potential concerns. Participation opportunities will continue during the environmental process.
Comments and suggestions on the project’s environmental scope were invited from all interested parties through October 31, 2017. The project scoping comment period is now closed.
