Do you think California's high-speed rail project is making real progress?

The California High-Speed Rail Authority completed the Hanford Viaduct, a structure just over one mile long with more than 300 columns, east of Hanford at Highway 43. Local and state leaders marked the milestone at a Thursday, November 12, 2026 ribbon-cutting in Hanford.

Why it matters

The viaduct carries the project over the San Joaquin Valley Railroad and Highway 198 and will connect to the planned Kings/Tulare Regional High-Speed Rail Station. Its completion adds to the construction progress reported across the first 119-mile portion of the project in California's Central Valley.

The viaduct is just over one mile long and has more than 300 columns, nearly twice the size of the Cedar Viaduct. Officials report 70 of 92 viaducts and 77% of guideways are complete in the first 119-mile leg, with the remaining work's timeline not specified.

The players

California High-Speed Rail Authority

The state agency responsible for planning and building California's high-speed rail system, which is delivering the project in phases starting with the Central Valley segment.

The details

The ribbon-cutting took place at 11 a.m. in Hanford, where California Transportation Secretary highlighted the overpass's size. The viaduct will carry high-speed rail trains over the San Joaquin Valley Railroad and Highway 198 between Grangeville Boulevard and Hanford Armona Road.

Construction Progress

The Hanford Viaduct adds to the first 119-mile Central Valley segment of the California High-Speed Rail Project, where 70 of 92 viaducts are now complete. The milestone shows the segment advancing toward the Kings/Tulare Regional High-Speed Rail Station.

Californians traveling through Hanford and the Central Valley will see the viaduct cross over Highway 198 and the San Joaquin Valley Railroad. The structure signals future high-speed rail service, though the extraction gives no date for when trains will run.

The takeaway

Large infrastructure projects like the Hanford Viaduct are built in stages, and completed segments such as this one show progress on the broader system. Readers tracking the project can watch for updates on the remaining viaducts and guideways in the Central Valley.
