CAPITAL PROJECT FACT SHEET PN: 1445000
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
Interstate 80/Ashby Avenue (SR-13)
Interchange Improvements
PROJECT OVERVIEW
DECEMBER 2021
PROJECT NEED
• The existing I-80/Ashby interchange provides no
access to Shellmound Street to/from westbound I-80
nor from Shellmound Street to Frontage Road.
• All westbound traffic to access Emeryville must use
the Powell Street interchange.
• There is no direct pedestrian and bicyclist access to the Bay Trail from Shellmound Street.
PROJECT BENEFITS
• Improves mobility and reduces congestion on Ashby
Avenue at the I-80/Powell Street interchange and at
the intersection of Ashby Avenue and 7th Street
• Provides safe access for pedestrians and bicyclists to connect across I-80, linking the San Francisco Bay Trail to the City of Emeryville and Berkeley’s Aquatic Park
