Route Description
Interstate 470 begins in the northwestern part of Topeka at an interchange with I-70, US-40, and K-4. US-75 approaches the interchange from the east and joins I-470. The two routes head southeastward along the western edge of the city. Along this stretch of the interstate, there are three interchanges; exits 1B, 2, and 3. Because of both the southeast-to-northwest alignment of the road and the proximity of two cross-streets, exits 1B and 3 are each made up of two half-diamond interchanges. At exit 1B, traffic leaving eastbound I-470 is deposited onto Huntoon Street. Vehicles merging onto eastbound I-470 must access the entrance ramp from Wanamaker Road. The intersection of Huntoon and Wanamaker is adjacent to the freeway. Exit 3 is constructed similarly to exit 1B, while exit 2 is a standard diamond interchange.
Through southern Topeka, I-470 / US-75 curve to the east-southeast where they intersect Gage Boulevard. Further southeast, US-75 splits away from I-470 at a complex interchange with Burlingame Road. Just east of the US-75 interchange, a trumpet interchange provides access to Topeka Boulevard. The highway then passes through a toll plaza and merges with the Kansas Turnpike, making I-470 into a toll road. This junction also marks the northern end of I-335. I-470 and the Kansas Turnpike head northeast towards I-70. The tollway continues northeastward through southeastern Topeka, passing near to Lake Shawnee and eventually reaching I-470's terminus at I-70, which the turnpike carries east.
The freeway is maintained by the Kansas Department of Transportation (KDOT), who is responsible for maintaining and constructing highways in Kansas. As part of this role, KDOT surveys traffic on their highways in terms of average annual daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2007, KDOT calculated that as few as 10,370 vehicles used I-470 daily along the Kansas Turnpike near the I-70 interchange and as many as 43,000 vehicles used I-470 daily west of the Gage Boulevard interchange. As part of the Interstate Highway System, the entire route is listed on the National Highway System, a system of roads that are important to the nation's economy, defense, and mobility.

Famous quotes containing the words route and/or description:
“A route differs from a road not only because it is solely intended for vehicles, but also because it is merely a line that connects one point with another. A route has no meaning in itself; its meaning derives entirely from the two points that it connects. A road is a tribute to space. Every stretch of road has meaning in itself and invites us to stop. A route is the triumphant devaluation of space, which thanks to it has been reduced to a mere obstacle to human movement and a waste of time.”
—Milan Kundera (b. 1929)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
