Idaho Avenue Overcrossing


A grade separation at Idaho Avenue taking traffic over future high-speed rail lines.


Along Idaho Avenue between State Route 43 and Seventh Avenue in Kings County.


The Idaho Avenue Overcrossing in Kings County continues to make progress. In May 2021, crews placed 270 cubic-yards of concrete for the deck of the superstructure. The superstructure is comprised of five pre-cast girders, large concrete beams used to support the top of the structure. Next, crews will install barrier rail on the structure. The overcrossing will span 205-feet long, 40-feet wide and will take traffic over the future high-speed rail tracks.
