On Oct. 28, 2020, the California High-Speed Rail Authority announced the completion of Poso Creek Viaduct in Kern County, the first completed structure in the 22-mile segment of high-speed rail from the Tulare-Kern county line to Poplar Avenue in Kern County known as Construction Package 4. It is the fourth high-speed rail structure completed in the Central Valley since August.
Construction on Poso Creek Viaduct, located south of Blankenship Avenue and west of State Route 43 just north of the City of Wasco, included several environmental protections. Crews followed strict guidelines and preventive measures to protect the Poso Creek bed with silt fencing and fiber rolls, and safely diverted area wildlife with exclusionary fencing.
The viaduct structure spans more than 240 feet long and 56 feet wide and will allow high-speed trains to cross over Poso Creek.
The Poso Creek Viaduct is located south of Blankenship Avenue and west of State Route 43 in Kern County.
