I-435, a loop route of Interstate 35, is 80.81 miles (130.1 km) long and intersects with nearly every other interstate highway in the Kansas City area (except for Interstate 635 and Interstate 670). An additional 2.8 miles (4.5 km) near Kansas City International Airport is signed along with Interstate 29 and U.S. Route 71, making I-435 the second-longest complete beltway numbered as a single Interstate Highway in the U.S., and fifth longest in the world after Cincinnati, Ohio's Interstate 275 at 83.71 miles (134.7 km), Houston, Texas's Beltway 8 at 88 miles (140 km), Berlin's Bundesautobahn 10 at 122 miles (196 km), and London's M25 motorway at 117 miles (188 km). The majority—52.8 miles (85.0 km)—of I-435 is within the state of Missouri, and most of that roadway lies within the city limits of Kansas City. The first/last exit is at I-435's parent route, Interstate 35, in Lenexa, Kansas. Going clockwise around Kansas City, the next exit is Exit 1A for Lackman Road. The milepost numbers do not start over when I-435 crosses the state line, but where it shares the same roadway as I-29, the latter's milepost (and therefore exit) numbering takes precedence.
I-435 in Kansas City was built piece by piece starting in the mid 1960-s and not finished until 1987.
In 1966, The first segment of Interstate 435 was built and opened between I-35 and US-69/ Metcalf Avenue near Overland Park, Kansas. A second segment was opened the same year between I-70 and US-50 in Eastern Kansas City, Missouri, but the two were not connected.
By 1969, I-435 was fully built between these two segments, through southern and eastern Kansas city.
By 1971, the freeway was extended from 23rd Street/ MO-78 to US-24.
In 1973, I-435 was extended north from the former terminus of US-24 across the Missouri River to I-35 in Claycomo, MO. It now extended halfway around the city.
By 1985, 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 MO-291/ Cookingham Drive at N. Reinking, 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 eight miles northwest, then exited, near Platte City and bore south on the west side of KCI. It crossed several small highways before crossing the Missouri River into Wyandotte County, Kansas. It continued generally south or southwest, crossed several state highways and I-70, then the Kaw River, before connecting with the former southwest end at K-10.
