In May 2023, the California High-Speed Rail Authority (Authority) and contractor Dragados-Flatiron Joint Venture (DFJV) announced the completion of the Idaho Avenue grade separation.
The overcrossing spans 205 feet and is 40 feet wide. The structure will take traffic over the future high-speed rail lines.
Construction crews are making headway at a number of high-speed rail grade separations in Fresno and Kings Counties – some of which are nearly completed. Both Dover Avenue and Idaho Avenue grade separations in Kings County are paved and ready to be striped and opened to traffic.
Crews have completed hauling dirt to form the slopes of the future overcrossing at Idaho Avenue. While the slopes settle, a temporary road has been built around the overcrossing to serve as a detour route while crews begin hauling fill to begin construction on an overcrossing to the south at Jackson Avenue.
This month, Idaho Avenue was closed to traffic to allow hauling to begin for construction of an overpass. More than 11,000 yards of dirt have been imported to the site as crews prepare the slopes and compact dirt for the structure. As many as 15 haul trucks are being used each day to transport the fill-dirt.
