Project Overview

Oakland Alameda Access Project

Project Footprint

The proposed Oakland Alameda Access Project provides a unique opportunity to address long-standing safety, mobility, and accessibility issues for communities within the project area that have endured these issues for decades.

This project was formerly known as the I-880/Broadway-Jackson Interchange Improvement Project.

The Oakland Alameda Access Project is intended to improve multimodal safety and reduce conflicts between regional and local traffic. It will also improve accessibility between I-880, SR-260 (the Webster and Posey Tubes), City of Oakland downtown neighborhoods, and the City of Alameda. Lastly, the project will reduce freeway-bound regional traffic and congestion on local roadways and in area neighborhoods.

The Oakland Alameda Access Project will also increase safety, accessibility, and connectivity for bicyclists and pedestrians between Chinatown, downtown Oakland, the Jack London District, and Alameda. Adding new bike lanes and sidewalks will increase foot and bike traffic and decrease car use in these crowded neighborhoods.

Purpose and Need Statement

All federally funded transportation projects have a purpose and need statement. “Need” is typically defined as a transportation deficiency. “Purpose” is typically defined as the objectives that will be met to address the transportation deficiency.

For the Oakland Alameda Access Project, Caltrans and Alameda CTC have developed the following purpose and need statement:

Project Purpose
  • Improve multimodal safety and reduce conflicts between regional and local traffic​
  • Enhance bicycle and pedestrian accessibility and connectivity within the project study area​
  • Improve mobility and accessibility between I-880, SR-260 (Tubes), City of Oakland downtown neighborhoods, and the City of Alameda​
  • Reduce freeway-bound regional traffic and congestion on local roadways and in area neighborhoods​
Project Need
  • Access between the freeway and the roadway networks between I-880 and the SR-260 (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​
  • I‑880 viaduct limits bicycle and pedestrian connectivity between downtown Oakland and the Jack London District

Project Timeline and milestones

I-880, including on- and off-ramps, was originally constructed in 1957. In the last 25 years, there have been several unsuccessful attempts to address various safety, congestion, and connectivity issues related to vehicular, bicycle, and pedestrian movements in the area. Although progress was made with each effort, no project was able to garner enough consensus to move forward.

Starting in 2014, Alameda CTC embarked on a concerted effort to address the complex safety, traffic, and connectivity issues and constraints in the project area.

Stakeholder Outreach

Since 2015, the Oakland Alameda Access Project team has conducted extensive engagement and public outreach on the proposed project. The Team has held over 250 meetings with a diverse group of stakeholders. Essential design elements have been incorporated into the project to address stakeholders’ comments and concerns.

Where We Are Now

Technical studies for the Oakland Alameda Access Project have been completed and summarized in the Draft Environmental Impact Report and Environmental Assessment and Draft Individual Section 4(f) Evaluation (“Draft Environmental Document”).

The Draft Environmental Document has been prepared in accordance with the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). Caltrans and Alameda CTC are now welcoming the public’s comments on the Draft Environmental Document.

The Draft Environmental Document is also available on the Alameda CTC website and the Caltrans website.

Project Funding

The total project cost is $119.9 million. The estimated cost of approximately $83 million for planning and construction of the Oakland Alameda Access Project has been secured through a number of sources, including federal, state, regional, and local funds such as Measures B and BB. Funding for remaining $34 million has yet to be secured.

Other Support$18,628$18,628$0
Right of Way and Support$4,800$4,800$0
