Interstate 70 (I-70) is a mainline route of theInterstate Highway System in the United States connectingCove Fort, Utah, toBaltimore, Maryland. In the US state ofKansas, I-70 extends just over 424 miles (682 km) from theColorado border near the town ofKanorado to the Missouri border inKansas City. I-70 in Kansas contains the first segment in the country to start being paved and to be completed in the Interstate Highway System. The route passes through several of the state's principal cities in the process, includingKansas City,Topeka, andSalina. The route also passes through the cities ofLawrence,Junction City, andAbilene.

The section of I-70 from Topeka to the Missouri border is co-designated as theKansas Turnpike; only the section between Topeka and just west of Kansas City is tolled.

I-70 runs concurrently withU.S. Highway 24 (US 24) from the Colorado state line until US 24 splits atLevant and runs north of I-70. AtColby, I-70 begins to turn southeast until it reachesOakley, whereUS 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 theHigh 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 ofstone posts in the countryside.^[2] ApproachingRussell, 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 theSmoky Hill River and its tributary, theSaline River, where the highway passes through theSmoky Hills Wind Farm. Reaching the county line betweenRussell andEllsworth counties, the road begins to traverse theSmoky Hills.

AtSalina,I-135 begins its journey southward towardWichita, and I-70 continues throughAbilene andJunction City, where the road begins to run through theFlint Hills.

InTopeka, I-70 intersects a child route,I-470, twice. The second time it is intersected, theKansas Turnpike merges, making I-70 into atoll road. This is one of only two sections of I-70 that are tolled (the other is along thePennsylvania Turnpike); as of 2024^[update], the maximum toll for cars withK-TAG on this section of I-70 is $2.74.^[3] I-70 and the turnpike are concurrent from Topeka toBonner Springs, the turnpike's eastern terminus. From Bonner Springs to18th Street and extending on to the Kansas eastern border, the highway is free.

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

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

The section of I-70 that is now theKansas Turnpike was finished by 1956 and opened to traffic.^[4][5] West of Topeka, the freeway was constructed from Topeka west toSalina at its junction withUS 81, as well as fromOgallah toGrainfield.^[6] From Salina, the freeway was completed throughWilson the next year. On October 9, 1959, the section of I-70 opened from Junction City west to Abilene through a ribbon-cutting ceremony.^[7] A segment of I-70 fromLevant through Ogallah was finished by 1965.^[8] Another section was built the following year connecting Wilson to Grainfield.^[9] The freeway was completed through Kansas with a last section near theColorado border in 1970.^[10]

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 theKansas Turnpike and use its mileposts (numbered nominally north from the Oklahoma border) instead.
