San José to Merced

The San José to Merced project section of the California high-speed rail system will provide a critical rail link between Silicon Valley and the Central Valley. The project section runs from the city of Santa Clara, through San José at Diridon Station to Gilroy, across the Pacheco Pass, and including the Central Valley Wye extending north to Merced and south to Fresno.

The San José to Merced project section overlaps with the San Francisco to San José project section to the north and the Central Valley Wye project section to the east. This route will run from the city of Santa Clara, through Diridon Station in downtown San José to Gilroy, across the Pacheco Pass, to the western limits of the Central Valley Wye, approximately nine miles northeast of Los Banos in Merced County. The Authority Board of Directors adopted the Final EIR/EIS in April 2022, selecting a preferred alignment that will modernize and electrify the existing rail corridor between San Jose and Gilroy, allowing for both electrified high-speed rail and Caltrain service. East of Gilroy, the alignment includes more than 15 miles of tunnels through the Pacheco Pass in the Diablo Mountain Range.




What's New

On April 28, 2022, the California High-Speed Rail Authority’s (Authority) Board of Directors certified the Final Environmental Impact Report/Environmental Impact Statement (EIR/EIS) and approved the San Jose to Merced project section in Northern California. This action completes the environmental clearance for nearly 400 miles of the high-speed rail project’s 500-mile Phase 1 alignment from San Francisco to Los Angeles/Anaheim. 

The Board’s actions mark their first certification of an environmental document in the Northern California region and the first in the San Francisco Bay Area. 

The Final EIR/EIS can be found on the Authority’s website: View the project section environmental documents.

Throughout the process, Authority staff will continue to engage stakeholders and communities along the corridor.

Public Involvement & Community Outreach

The Authority encourages public engagement to advance California high-speed rail in Northern California so that the final project reflects the needs and vision of our community as a whole.

We conduct outreach events including Open Houses, Community Working Groups, and attending regional events throughout Northern California to inform and gather input from local communities, policymakers, and stakeholders. Stakeholders include environmental justice groups, community organizations, city/county staff, neighborhood groups, and California residents.
