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 22nd 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 22nd 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

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
