In January 2016, the California High-Speed Rail Authority awarded Construction Package 4 (CP4) to California Rail Builders (CRB) for $444 million. CP4 consists of 21 miles of new closed-corridor double-track high-speed train (HST) guideway starting 1-mile north of the Tulare/Kern County line, through Wasco California, and ending at Poplar Ave in Kern County, north of Shafter. The HST system is designed to accommodate passenger rail service up to 220 mph. CP4 is the third package of High-Speed Rail project to be released, following CP1 and CP2-3. The majority of the CP4 HST alignment is parallel and adjacent to the BNSF high-volume Bakersfield Subdivision main line, requiring numerous new railroad grade separations. The CP4 work includes 2 new railroad overpasses, 2 new railroad underpasses with 2 separate and adjacent railroad shooflies, 1 HST viaduct structure, 1 pedestrian underpass, 6 HST roadway underpasses and over 45 utility relocations within the BNSF right-of-way. In addition to maintaining the active BNSF freight operations, the downtown Wasco segment has an existing Amtrak station that was a key constraint for the project and added complexity to the design. This paper will emphasize the close involvement and collaboration with BNSF for the shooflies and structure designs and provide specific details on how the design evolved and the innovative solutions that were developed to balance the requirements of BNSF, Amtrak and other key stakeholders to streamline the approval process and quickly move the project into construction. *Missed this Session or want to view it again?
