History

I-435 in Kansas City was built piece by piece starting in the mid-1960s and not finished until 1987. In 1965, the first segment of I-435 was built and opened between I-35 and US 69 (which, at that time, was signed with Metcalf Avenue) near

and US 50 in eastern Kansas City, Missouri, but the two were not connected. The eastern segment of I-435 was extended south to Gregory Boulevard and north past 23rd Street/ Route 78 by 1968. By 1969, I-435 was fully built between these two segments, through southern and eastern Kansas City. The freeway was extended from 23rd Street/Route 78 to US 24 two years later. In 1973, I-435 was extended north from the former terminus of US 24 across the Missouri River to I-35 in Claycomo. It now extended halfway around the city. In 1983, a small segment was opened on the outskirts of Kansas City north between US 169 and Route 291 near Kansas City International Airport (KCI). Later, this small segment was connected with the rest of the freeway. A segment was built heading almost due north from I-35 in Claycomo to Route 291/Cookingham Drive at North Reinking Road, curving due west from there to US 169. In this year, the southwest end was also extended to K-10. In 1987, the freeway was opened all the way around the city. The northwest end was signed on I-29 for northwest, then exited near Platte City and bore south on the westside of KCI. It crossed several small highways before crossing the Missouri River into
