The Tule River Viaduct will take high-speed trains over State Route 43, the BNSF freight line and the Tule River in Tulare County.


South of Avenue 144 / Poplar Avenue and State Route 43, to the south of the Tule River.


In Tulare County, crews have completed more than 100 Cast-in-Drilled-Holes to provide the foundation of the Tule River Viaduct. CIDH piles can be as large as 11-feet in diameter and are drilled up to 200-feet deep. Across the structure, crews are installing rebar and placing concrete to form the footings and future columns. As of Spring 2022, 32 of the 75 columns of needed for the Tule River Viaduct are now complete. Crews will be gearing up to install the falsework necessary to form the pergola section of the structure later this spring. When complete, the Tule River Viaduct will be more than 3,573 feet long.
