Share via:


OVERVIEW

The California Department of Transportation (Caltrans), in cooperation with the Alameda County Transportation Commission (Alameda CTC), proposes to widen and conform State Route (SR) 84 to expressway standards between south of Ruby Hill Drive and the Interstate 680 (I-680) interchange. 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.
