KINGS COUNTY, Calif. - The California High-Speed Rail Authority completed its 61st structure in Central Valley.
The 61st structure, the Jersey Avenue grade separation on State Route 43, will improve safety and traffic flow near the high-speed rail corridor, says CHSRA. Over the next 30 years, the King County grade separation will result in an estimated $137 million in safety benefits and 670 crashes prevented, based on KCAG Safety Data.
The grade separation opened to traffic back on May 20 and is located between Jackson and Kent Avenues on SR43. The structure measures 437 feet long and more than 43 feet wide. This structure is one of two grade separations that will move traffic over high-speed rail. According to the release, the structure is a cast-in-place, box girder bridge with no pre-cast elements. Crews used more than 2,400 cubic yards of concrete and 575,298 pounds of steel.
Authority Chief of Construction Ed Fenn said, “We’re especially proud to see the State Route 43 at Jersey Avenue grade separation open to traffic. This structure is a major safety improvement for Kings County, improving the flow of traffic and creating a smoother, more reliable connection for drivers, businesses, and farm operations along this critical stretch of the highway. As we continue to advance construction across the Valley, projects like this show how high-speed rail is already delivering real, tangible benefits to local communities.”
