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

The Alameda County Transportation Commission (Alameda CTC), in cooperation with the California Department of Transportation (Caltrans) and the cities of Berkeley and Emeryville, proposes to reconstruct the I-80/ Ashby Avenue interchange to improve accessibility, safety, traffic flow, and bicycle and pedestrian facilities. These improvements are intended to provide traffic congestion relief and enhanced mobility at this critical access point and important intersection of regional transportation routes. The project will also provide multimodal transport options, while improving community connectedness, including connectivity to the existing 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. It will provide a direct connection between westbound Interstate 80 (I-80) and Emeryville by way of Shellmound Street.

Improvements will include:
  • A new bridge to replace existing bridges
  • A new interchange form with connections to Shellmound Street and Frontage Road
  • Provision of bicycle and pedestrian access over the I-80 freeway at the Ashby Avenue interchange

The California Department of Transportation (Caltrans) in partnership with Alameda County Transportation Commission (Alameda CTC), along with the cities of Berkeley and Emeryville, are proposing to reconstruct the I-80/Ashby Avenue interchange to improve access, safety, traffic circulation, and bicycle and pedestrian connections.

Caltrans and Alameda CTC are holding the first open house to inform the public about the improvements being planned for this interchange. We are looking for input from community members, elected officials, business owners, and anyone else who frequents this busy interchange. Please join us for light refreshments, a slideshow and open discussions.
