Travel directions

The starting point of I-435 is not on the border between Missouri and Kansas, but at Interstate 35 in Kansas. The highway crosses the Missouri-Kansas border at the Leawood suburb. The highway here has 2×4 lanes and runs to the west. You pass through a business park in Overland Park, a suburb of 149,000 inhabitants, and also the second largest city in Kansas. A cloverleaf crosses US 69, the southern approach to the conurbation. Shortly thereafter, the start and end of I-435 is crossed at Interstate 35, the highway from Wichita to Kansas City.. This is followed by a large parallel structure with a maximum of 18 lanes and braids. Immediately afterwards, K-10 turns west, as a highway to Lawrence. I-435 then turns north and has 2×3 lanes. One then passes through the suburbs of Lenexa and Shawnee and then crosses the Kansas River.

Kansas Speedway crosses Interstate 70, the highway from Denver and Topeka. After this, 2×3 lanes are also available, passing through the westernmost neighborhoods of Kansas City. They then cross the Missouri River, also the border with the state of Missouri. Interstate 435 in Missouri then continues north to Kansas City.

The Kansas City ring road was built in the state of Kansas in two separate periods. The South Ring, east of I-35, was completed in 1965 and 1969. The western ring was built much later. The first part of this opened in 1981, a short part with the bridge over the Kansas River. It wasn’t until 1986 that the ring was significantly opened, with the final section in 1987, including the bridge over the Missouri River.


I-435 has been gradually widened to 2×5 lanes along the south side of Kansas City. The first section, close to the Missouri border, was widened to 2×5 lanes as early as the late 1990s. The widening was gradual westward, and in 2008 the portion east of US 69 was also widened to 2×6 lanes.

In the southern suburb of Overland Park, I-435 between I-35 and US 69 has been widened to 2×6 lanes. A wickerwork to the west of the interchange with US 69 has also been realized. Overland Park is Kansas City’s largest suburb and located in an area of ​​significant population growth. This project was carried out between July 2011 and November 1, 2013.

Between 2014 and 2016, the large “Johnson County Gateway” (Joco Gateway) project was completed on the southwestern portion of I-435. The interchanges of I-435 with I-35 and K-10 at the Lenexa suburb have been reconstructed and additional connecting roads and braids have been constructed. Traffic from K-10 to I-35 and vice versa has been interwoven with traffic on I-435 ever since. The highway has become more than twice as wide at the site. The $288 million project was officially completed on November 29, 2016.

Interstate 470 or I -470 is an Interstate Highway in the U.S. state of Kansas. The highway forms the southern bypass of the capital Topeka and is partly a toll road, part of the Kansas Turnpike. The highway is 22 kilometers long.

Travel directions

The highway branches off Interstate 70 from Denver on the west side of Topeka. The highway has 2×2 lanes and passes through the western neighborhoods of Topeka. On the south side of Topeka, US 75 ends as a freeway on I-470. After that, I-470 merges into the Kansas Turnpike, where Interstate 335 ends. The toll road then passes east of Topeka. I-70 merges with the toll road here and continues to form the Kansas Turnpike to Kansas City. The I-470 ends here.


The eastern portion of I-470 is part of the Kansas Turnpike, which opened on October 20, 1956. The rest opened around 1961 along the west side of Topeka.
