closed

Other Agencies with Actions or Authorizations: California Description: 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
