Interstate 70 in Kansas

Interstate 70 in Kansas, Exit 1, Kanorado

I-70 is concurrent with US-24 from the Colorado state line until US-24 splits at Levant and runs north of I-70. At Colby, I-70 begins to turn southeast until it reaches Oakley, where US-40 joins with I-70 for a concurrent journey through most of the state. Initially, the route remains high and unusually level as it follows a projection of the High Plains into the state. From Exit 140 (Riga Road), the route lowers from the High Plains into the Blue Hills region, as indicated by gentle undulations in the road and the unusual appearance of stone posts in the countryside.[2] Approaching Russell, the route passes over three active sinkholes, the largest being the Crawford Sinkhole at Mile 179.[2] Past Russell, the route follows a ridge between the Smoky Hill River and its tributary, the Saline River where the highway passes through the Smoky Hills Wind Farm. Reaching the county line between Russell and Ellsworth counties, the road begins to traverse the Smoky Hills.

At Salina, Interstate 135 begins its journey southward toward Wichita, and I-70 continues through Abilene and Junction City, where the road begins to run through the Flint Hills.

In Topeka, I-70 intersects a child route, I-470, twice. The second time it is intersected, the Kansas Turnpike merges, making I-70 into a toll road. This is one of only two sections of I-70 that are tolled (the other is along the Pennsylvania Turnpike), with the maximum toll distance costing $3.50 as of 2018.[3] I-70 carries this designation from Topeka to Bonner Springs. It is the eastern terminus of the turnpike, and from there to 18th Street and extending on to the Kansas eastern border, the highway is free.

I-70 crossing on the Lewis & Clark Viaduct over the Kansas River from Kansas to Missouri in Kansas City, as seen from Quality Hill.

I-70 enters Missouri via a main northern route on the Lewis and Clark Viaduct above the confluence of the Kansas River and Missouri River and a route designated "Alternate I-70" which has signs for I-70 as well as Interstate 670 just south of Kansas City main downtown area.

Exit sign for exit 115 in Collyer. I-70 in Kansas is known for being unusually level.

I-70 enters Missouri via a main northern

From Exit 275 at Abilene to the Missouri state line, the road is named the Dwight D. Eisenhower-Harry S. Truman Presidential Highway. It retains the designation until Exit 16 in Missouri at Independence, the location of Truman's presidential library.

The section of I-70 that is now the Kansas Turnpike was finished by 1956 and opened to traffic.[4][5] West of Topeka, the freeway was constructed from Topeka west to Salina at its junction with U.S. Route 81, as well as from Ogallah to Grainfield.[6] From Salina, the freeway was completed through Wilson the next year. A segment of I-70 from Levant through Ogallah was finished by 1965.[7] Another section was built the following year connecting Wilson to Grainfield.[8] The freeway was completed through Kansas with a last section near the Colorado border in 1970.[9]

Exit numbers correspond to the mileposts where they are located (numbered east from the Colorado border), except for those between Topeka and Kansas City, which are part of the Kansas Turnpike and use its mileposts (numbered nominally north from the Oklahoma border) instead.
