Highlights from Chapter 4:

Advancing Statewide: Progress in the Central Valley, Northern and Southern California

Progress continues across the 171 miles under construction and development in the Central Valley, including more than 30 active construction sites and 69 structures or grade separation projects either underway or completed. Beyond laying the foundation for high-speed rail infrastructure, these structures are already improving safety and air quality along high-speed rail’s alignment.

As the Authority focuses on construction in delivering the Merced to Bakersfield line, significant progress continues in Northern and Southern California, particularly with advancing environmental approvals. With 422 miles now environmentally cleared from San Francisco in the north to Palmdale in Los Angeles County in the south, efforts focus on completing environmental review of the remaining two project sections in Southern California.

This chapter gives an overview of the progress being made in California’s regions, including milestones since the 2022 Business Plan. It also takes a look at activities that are currently underway and milestones to come over the following years.
