  • April 2021 drone footage of the Wasco Viaduct. www.BuildHSR.com (Projects) .... OVERVIEW The Wasco Viaduct will take high-speed trains over the existing BNSF freight tracks and will be nearly 2,000 feet long when complete. LOCATION The Wasco Viaduct is located south of the City of Wasco near Jackson Avenue. CURRENTLY The Wasco Viaduct continues to take shape with plenty of work happening across the entire structure. To the north, crews are placing temporary forms for future sound walls that will reach 34-feet high. Close by, crews are placing the bulk head on the end of the section footing in preparation for a concrete pour. Nearly 290 cubic-yards will be needed for the footing. At the pergola section crews continue to tie rebar on the upper edge girders while carpenters are placing forms for the upper edge girder for concrete placement.
