Interstate 470 (I-470) is a 13.72 mi loop highway that bypasses the downtown area of Topeka, Kansas. I-470 begins at an interchange with Interstate 70 in western Topeka and heads generally southeast, running concurrent with U.S. Route 75 (US-75). The concurrency with US-75 ends 5.74 mi later at the Burlingame Road interchange. I-470 becomes part of the Kansas Turnpike at its junction with Interstate 335. From there, the highway heads generally northeast through the southeastern sections of Topeka. After traveling 7.03 mi as the Kansas Turnpike, I-470 reaches its eastern terminus with Interstate 70. The Kansas Turnpike was opened in the 1950s, comprising the eastern portion of the route. In the late 1950s construction began on the western portion of I-470, and on October 21, 1960, the western section of I-470 was dedicated and opened to traffic. In 1982, Interstate 470 was designated as "Martin Luther King Jr. Memorial Highway". The routing of I-470 has not changed since the completion of the highway.
