Southbound Interstate 680 Express Lane and Pavement Rehabilitation Project Breaks Ground

Yesterday, Alameda County Transportation Commission (Alameda CTC) and the California Department of Transportation (Caltrans) broke ground on the Southbound Interstate 680 Express Lane and Pavement Rehabilitation Project, paving the way for a smoother, less congested ride for thousands of motorists. The project will build a new express lane on I-680 between State Route 84 and Alcosta Boulevard in San Ramon, closing the gap between existing and in-process express lanes to ease the commute for southbound I-680 commuters. The project will also rehabilitate the pavement on this nine-mile stretch of I-680.

“Today is an important step in completing an almost fifty-mile express lane corridor for people to travel on I-680 in Alameda and Contra Costa Counties and delivering on our promise to Alameda County voters,” noted Alameda CTC’s Vice Chair David Haubert.

“We are grateful to our project and funding partners at Caltrans, the California Transportation Commission and the Metropolitan Transportation Commission for their support,” said Alameda CTC Executive Director Tess Lengyel.

Funding for the overall project is a combination of local ($112 million), regional ($80 million), and state/federal funds ($134 million), that includes funding from the Alameda County voter-approved Measure BB, Regional Measure 3, and State Transportation Improvement Program (STIP), Senate Bill 1 (SB-1), and State Highway Operation and Protection Program (SHOPP).
