I-80/Ashby Avenue (SR-13) Interchange Improvements

The Alameda County Transportation Commission (Alameda CTC), in collaboration with the California Department of Transportation (Caltrans) and the cities of Berkeley and Emeryville, proposes to reconstruct the I-80/Ashby Avenue interchange to ease congestion, provide better interstate access, and connect pedestrians and cyclists to the San Francisco Bay Trail.

A critical gateway to Emeryville and Berkeley, this voter-approved project will enhance, support and connect the community.

Improvements will include:
  • A new interchange structure to supply better connections to Shellmound Street, Frontage Road, and Point Emery
  • New bridges to provide vertical clearance along I-80 for freight vehicles
  • A new shared bicycle and pedestrian pathway to afford direct access to the San Francisco Bay Trail

This project was approved by Alameda County voters in 2014 under Measure BB and represents a direct investment in regional infrastructure and economic development.

2022 Open House

On January 11, 2022, Caltrans and Alameda CTC held a virtual public open house to present an overview of the Draft Environmental Document (DED) and its appendices, and to inform the public about the benefits and environmental impacts of the I-80/Ashby Avenue interchange improvements.

Comments on the DED continued to be submitted during the 45-day comment period through January 31, 2022. Details on submission can be found on the Overview and Resources tabs.

2019 OPEN HOUSE

The public was invited to attend an open house to learn about the project on May 22, 2019 at the South Berkeley Senior Center at which the following materials were presented.

Draft Environmental Document

The Draft Environmental Document (DED) and its appendices for the I-80 Ashby Improvement Project have been prepared in accordance with the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA) and are now available for public review. The DED describes and evaluates the potential environmental impacts of this project.

The DED is now being circulated to the public for review and comment. Comments will be accepted between December 15 and January 31, 2022.

The DED can be downloaded and reviewed from this website. Digital copies of the DED are also available on the Caltrans website.

Technical studies, as well as printed copies of the reports, are available upon request. The limited access to hard-copy viewing of the DED is due to the ongoing COVID-19 pandemic.

After receiving comments from the public, a Final Environmental Document will be prepared. Caltrans may prepare additional environmental and/or engineering studies to address comments, if needed.

The Final Environmental Document will include responses to formal comments received on the DED and will identify the preferred alternative(s). If the decision is made to approve the project, a Notice of Determination (NOD) will be published in compliance with CEQA.

When the NOD is made public, Caltrans will decide whether to issue a Finding of No Significant Impact (FONSI) or to require an Environmental Impact Statement (EIS) to comply with NEPA. A Notice of Availability (NOA) of the FONSI will be sent to the affected federal, state, and local government agencies, and to the State Clearinghouse.

Comment on the Draft Environmental Document

There are several ways to provide formal comments on the Draft Environmental Document. For all comments, please be sure to include (at a minimum) your last name and zip code or your comment will not become part of the official record.

Frequently Asked Questions

Ashby Avenue is an important gateway to the cities of Emeryville and Berkeley. Currently, the I-80/Ashby Avenue Interchange has no connection between Shellmound Street and westbound I-80, nor between Shellmound Street and Frontage Road. Motorists traveling westbound can access the City of Emeryville only through the I-80/Powell Street Interchange. Taller freight trucks must also exit the I-80 and take surface streets instead. Taller freight trucks must also exit the I-80 and take surface streets instead.

The proposed project will provide a direct connection to the City of Emeryville for motorists on westbound I-80 as well as a direct connection to the San Francisco Bay Trail and Frontage Road for bicycles and pedestrians. It will also provide clearance for freight trucks, allowing them to avoid taking surface streets.

This project was included in the voter-approved 2014 Alameda County Transportation Expenditure Plan. Alameda CTC and partner agencies are working to deliver upon this promise.
The interchange improvements will enhance connectivity for all travelers, including motorists, cyclists and pedestrians, by:
  • Improving interstate access by car from both sides of I-80
  • Providing direct access to the San Francisco Bay Trail for pedestrians and cyclists
  • Increasing safety through incident management
The Draft Environmental Document (DED) and its appendices for this project are complete. Alameda CTC and Caltrans are accepting comments on the DED.

The remaining project schedule includes the following major milestones and estimated time frames:
  • Formal comment period for the Draft Environmental Document (DED) – December 15-January 31, 2022
  • Online Open House – January 11, 2022
  • Final design – mid 2022
  • Construction – late 2022 to early 2025
I-80/Ashby Avenue interchange improvements will ease traffic by improving interstate access while supporting pedestrians and cyclists.

The proposed project will provide a direct connection for motorists between Shellmound Street and westbound I-80 and realign access to West Frontage Road. The new interchange will replace the existing elevated interchange connector ramps with a new bridge over I-80, allowing freight trucks to remain safely on I-80 instead of exiting and reentering I-80 via local surface streets.

For bicyclists and pedestrians, the new interchange will introduce a new bicycle and pedestrian overcrossing and connection from 65th Street and Shellmound Street to the San Francisco Bay Trail.

You and all community members are invited to provide input on the Draft Environmental Document and its appendices during the formal public comment period, December 15, 2021 to January 31, 2022.

You are also invited to a virtual public open house on January 11, 2022. A recording of the open house will be posted on this website thereafter.
