The California High-Speed Rail Authority and design-build contractor, California Rail Builders have placed the final pre-cast girders for Construction Package 4 of California’s high-speed rail project, marking a major construction milestone.
Overnight on 8 July 2022, construction crews placed 12 pre-cast concrete girders over the State Route 46 underpass in Wasco. These girders will create a bridge to allow high-speed trains to run parallel to the BNSF railroad.
With this placement, all structures along the 22-mile high-speed rail line between the Tulare/Kern county line and Poplar Avenue south of Wasco are now in construction.
This milestone follows the installation of 15 pre-cast girders at the Merced Avenue Grade Separation south of Wasco last month, where the girders span more than 177 feet. In addition, the last four of 120 pre-cast concrete girders were also placed on the pergola section of the Wasco Viaduct in spring 2022.
119 miles of the California high-speed rail line are currently under construction in the Central Valley, with more than 30 active construction sites.
