The Project
Californiaโs high-speed rail project is one of the most ambitious infrastructure undertakings in U.S. history. First approved by voters in 2008, the project promised a modern, eco-friendly transportation network connecting San Francisco to Los Angeles in under three hours. It aimed to revolutionize travel in the Golden State by providing a fast, efficient alternative to congested highways and short-haul flights while reducing greenhouse gas emissions.
However, the journey has been anything but smooth. Spiraling costs, political battles, and construction delays have led to major shifts in scope and expectations. What was once envisioned as a 520-mile corridor stretching from the Bay Area to Southern California has, for now, been scaled back to a 171-mile segment in the Central Valley between Merced and Bakersfield. Despite the hurdles, construction is moving forward, and significant milestones are being reached.
Current Construction Progress
As of 2025, construction continues across Californiaโs Central Valley, where crews are actively working on bridges, viaducts, grade separations, and track systems. Some of the latest developments include:
- Railhead Launch in Wasco: In January 2025, Governor Gavin Newsom and California High-Speed Rail Authority (CHSRA) CEO Ian Choudri celebrated the start of track and systems construction in Wasco. This milestone follows the near completion of civil works in Construction Package 4 (CP 4), which covers a 22-mile stretch from Tulare-Kern County to Poplar Avenue in Shafter.
- McKinley Avenue Overpass in Fresno: In December 2024, the CHSRA broke ground on a 402-foot-long, four-lane grade separation project at McKinley Avenue and Golden State Boulevard. Once completed, the overpass will improve safety for vehicles, cyclists, and pedestrians near the future high-speed rail tracks.
- Over 14,500 Construction Jobs Created: According to the CHSRAโs 2024 Economic Impact Report, the project has generated thousands of jobs, particularly in the Central Valley, with more than 3,200 workers involved in CP 4 alone.

Financial and Political Challenges
Despite tangible progress, securing funding remains a major obstacle. The projectโs cost estimates now range between $89 billion and $128 billion, significantly higher than the original $33 billion estimate in 2008. Critics argue that unless new funding sources emerge, even the scaled-back Merced-to-Bakersfield segment could stall.
A recent blow came from the U.S. House of Representatives, whose FY 2025 budget bill explicitly blocks federal funding for Californiaโs high-speed rail. While the Senateโs version does not include this restriction, the projectโs dependence on federal dollars remains uncertain. Governor Newsom and the CHSRA continue to lobby for additional funding, arguing that completing the Central Valley segment will demonstrate the projectโs viability and attract further investment.
Whatโs Next for California High-Speed Rail?

The CHSRA maintains that the Merced-to-Bakersfield corridor will be operational by the early 2030s, with expansion to the Bay Area and Los Angeles contingent on future funding. If successful, Californiaโs high-speed rail could lay the foundation for a broader national network, similar to the bullet train systems of Europe and Asia.
However, the project still faces a long road ahead. The next few years will be crucial in determining whether Californiaโs high-speed rail dream will become a transformative realityโor remain an expensive, unfinished promise.
