Editing Interstate 70 (section)

{{Main|Interstate 70 in Kansas}}
Coming from Colorado, I-70 enters the prairie, farmlands, and rolling hills of Kansas. This portion of I-70 was the first segment to start being paved and to be completed in the Interstate Highway System. It is given the nickname "Main Street of Kansas", as the Interstate extends from the western border to the eastern border of the state, covering {{convert|424|mi|km}} and passing through most of the state's principal cities in the process.

In [[Salina, Kansas|Salina]], I-70 intersects with the north terminus of [[Interstate 135|I-135]]. In [[Topeka, Kansas|Topeka]], I-70 intersects [[Interstate 470 (Kansas)|I-470]], twice. At the eastern intersection, the [[Kansas Turnpike]] merges, with I-70 becoming a [[toll road]]. This is one of only two sections of I-70 that are tolled. (The other is part of the [[Pennsylvania Turnpike]].) I-70 carries this designation from Topeka to Kansas City, the eastern terminus of the turnpike. About halfway between Topeka and [[Kansas City, Kansas|Kansas City]], I-70 passes through [[Lawrence, Kansas|Lawrence]] (home to the [[University of Kansas]]). The tolled portion of the turnpike ends near [[Bonner Springs, Kansas|Bonner Springs]], just west of Kansas City. There is also a third auxiliary route in Topeka, [[Interstate 335 (Kansas)|I-335]], which runs from I-470 south to meet up with I-35 in the [[Flint Hills]] town of [[Emporia, Kansas|Emporia]]. Just past the Bonner Springs Toll Plaza, I-70 crosses [[Interstate 435|I-435]] for the first time, which allows travelers to bypass the downtown traffic via I-435, which encircles the [[Kansas City metropolitan area]]. Further down the highway in Kansas City, approximately {{convert|3|mi|km|spell=in}} before the 18th Street Expressway, I-70 is intersected again by another auxiliary route. This route, [[Interstate 635 (Kansas–Missouri)|I-635]], runs from [[Interstate 35|I-35]] at its southern terminus up to [[Interstate 29|I-29]], just about {{convert|5|mi|km|spell=in}} across the [[Missouri River]], at its northern terminus. From I-635 to just past the [[U.S. Route 169|US&nbsp;169]] (7th Street) exit, I-70 runs adjacent [[Union Pacific Railroad]]'s Armourdale Yard. Here, [[Interstate 670 (Kansas–Missouri)|I-670]] (also designated "Alternate&nbsp;70" on some signs) diverges, providing a more direct route that rejoins I-70 proper a few miles east in Missouri. The highway passes over the former stockyards and railyard when it crosses the [[Kansas River]] on the [[Intercity Viaduct]] into [[Downtown Kansas City, Missouri]].<ref>{{cite map|publisher=Rand McNally|title=The 2014 Road Atlas|year=2014|page=58}}</ref>
