San José to Merced

The San José to Merced project section is part of the first phase of the California high-speed rail system that will provide a critical rail link between the Silicon Valley and the Central Valley. The approximately 84-mile project section will travel between stations in San José (Diridon Station) and Gilroy and (after passing through the Central Valley Wye) north to Merced or south to Fresno.

The focus of the San José to Merced project section is the area between San José and the Central Valley Wye. The Central Valley Wye is being studied separately as a supplemental environmental document for the Merced to Fresno project section.

This route will travel from Diridon Station in downtown San José, through the Pacheco Pass, to the western limits of the Central Valley Wye, approximately nine miles northeast of Los Banos in Merced County.

The Authority is working to environmentally clear the section between San José and the Central Valley Wye. Options range from a new dedicated high-speed rail corridor between San José and Gilroy to a shared corridor with electrified Caltrain service using the existing rail corridor.



What's New

The public review period for the San José to Merced Project Section Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) closed on June 23, 2020. The California High-Speed Rail Authority (Authority) will consider all comments received on the Draft EIR/EIS and respond to substantive comments on the Draft EIR/EIS in the Final EIR/EIS. The Draft EIR/EIS was originally made available for a minimum 45-day public review beginning on April 24, 2020 and ending on June 8, 2020, pursuant to the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA). In response to agency and stakeholder requests and in consideration of limitations caused by the novel coronavirus pandemic, the Authority elected to extend the public review period for 15 days to June 23, 2020. View the Draft EIR/EIS.

Please visit the Events Page for more information about engagement activities during the public comment period. Authority staff will provide written responses to all comments received, which will be published in the Final EIR/EIS, scheduled for release in 2021.

Public Involvement & Community Outreach

Below is a list of open houses and working group meetings we have conducted between fall 2019 and High-speed rail is our opportunity to modernize the Bay Area’s transportation system and leave a positive environmental legacy for our children and grandchildren. The Authority encourages public engagement in California high-speed rail construction and operations, so that the final project reflects the needs and vision of our community as a whole.

We conduct outreach events throughout Northern California, such as Open Houses and Community Working Group meetings, 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.

In response to the COVID-19 pandemic, the Authority created an open house website to provide access to information and resources for the Northern California project sections upon the release of the San Francisco to San José and San José Merced Draft Environmental Impact Reports/Environmental Impact Statements (EIRs/EISs). The website is regularly updated as more resources become available. Please visit to learn more.

Below is a list of open houses and working group meetings conducted between fall 2019 and winter 2020. For a listing of upcoming events and outreach opportunities in your area, visit the Events page. Due to Americans with Disabilities Act (ADA) requirements, meeting materials prior to June 2019 can be requested through a Public Records Act request.
