PROJECT DESCRIPTION:

Project B-1 is located at the I-580/I-680 Interchange in Alameda County. The proposed project limits are from 1,700 feet east of the Hacienda Drive Overcrossing to 2,000 feet west of the San Ramon Road Overcrossing along I-580, and from the Amador Valley Boulevard Undercrossing to 3,400 feet south of the Stoneridge Drive Overcrossing along I-680.

STATUS:

A Project Study Report-Project Development Support (PSR-PDS) was completed and approved by Caltrans in 2009.
The next steps in project development will be to:

Review the existing PSR-PDS to validate the information

Identify the need for updates/revisions to identify financially feasible improvements to address the latest safety, operational, and congestion issues

The Alameda CTC’s 2014 Transportation Expenditure Plan (TEP), approved as part of Measure BB, includes $20 Million in funding for I-580/I-680 Interchange improvements. Further project development is being explored. Alameda CTC is working with local, regional, and state agencies in identifying funding.
