SR-84 Widening and SR-84/I-680 Interchange Improvements Project

Caltrans, in cooperation with Alameda CTC, has released the Draft Environmental Impact Report/Environmental Assessment (EIR/EA) for the State Route 84 (SR-84) Expressway Widening and SR-84/Interstate 680 (I-680) Interchange Improvements Project. Caltrans is the lead agency under the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA). Alameda CTC is the implementing agency for the preliminary design and environmental review phase.

The project proposes to widen and conform SR-84 to expressway standards between south of Ruby Hill Drive and the I-680 interchange in southern Alameda County. The project would also improve SR-84/I-680 interchange ramps and extend the existing southbound I-680 high-occupancy vehicle/express lane northward by approximately 2 miles. The purpose of the proposed project is to alleviate traffic congestion, improve operations and safety, and improve bicycle access on SR-84 and at the SR-84/I-680 interchange.

You are invited to attend a public meeting and open house about the findings of the EIR/EA and the potential environmental effects of the proposed project. We welcome your comments and participation. Meetings will be held at the following locations and dates:
