Hanford Viaduct


Located in Kings County, the Hanford Viaduct will span more than a mile in length and will allow high-speed trains to cross over Grangeville Boulevard, San Joaquin Valley Railroad, and State Route 198.


North of the city of Hanford between Grangeville Boulevard and Hanford-Armona Road, east of State Route 43.


In August, crews began placing pre-cast concrete girders for the superstructure of the Hanford Viaduct. Each California wide flange girder ranges in size between 53 to 74-feet long and weighs between 60,000 to 90,000 pounds each. As many as 14 girders will be placed between each span of columns, and more than 900 girders will be needed all together. As of Oct. 1, 2022, more than 130 girders have been placed across 15 spans of columns.

Hanford Viaduct is the largest high-speed rail structure in the Central Valley spanning nearly 6,330 feet long. When complete it will carry high-speed trains over San Joaquin Valley Railroad and State Route 198.
