U.S. Route 40 in Kansas

US 40 enters Kansas near the unincorporated community of Weskan. The first sizable town it enters is Sharon Springs, where it intersects K-27. From there it goes northeast to Oakley and follows Eagle Eye Road before merging with I-70 east of town. The two routes remain merged until Topeka, although the prior alignment of US 40, named Old Highway 40, parallels I-70 for most of the way.^[2][3] From Ellsworth to Salina, the old alignment of US 40 is signed as K-140.

In Topeka, US 40 leaves I-70 at exit 366, follows the Oakland Expressway concurrent with K-4 north to 6th Avenue, then heads east along 6th Avenue out of town. Through Topeka, US 40 closely follows the route of the Oregon Trail.^[4] At the Shawnee-Douglas county line near Big Springs, US 40 crosses to the south of I-70 and enters Lawrence from the west along West 6th Street. At the west side of Lawrence, the route is joined by K-10 and travels south and east to the junction with US 59 and then runs north with US 59 to cross the Kansas River. It follows North 2nd and North 3rd Streets, crosses back under I-70, leaves US 59, and merges with US 24^[2][3] before leaving town.

US 40 remains merged with US 24 as the two routes travel northeast to the town of Tonganoxie. From there, the merged routes turn due east toward Kansas City, Kansas. In Kansas City, US 40 and US 24 intersect US 73 and K-7, and turning south toward Interstate 70. US 40, along with US 24, then merge onto I-70 and recross the Kansas River over the Lewis and Clark Viaduct just before entering Kansas City, Missouri.^[2][3][5]

On December 1, 2008, US 40, along with US 24 and US 73, was rerouted south along K-7 west of Kansas City to the intersection with I-70. Before this date, US 40 and US 24 continued along State Avenue to College Parkway before turning right to follow Turner Diagonal for 1⁄2 mile (800 m) where US 40 joined Interstate 70 for the duration of its journey eastward toward Missouri.

In 1951, the State of Kansas designated U.S. Route 40 as a Blue Star Memorial Highway from border to border.

By October 1967, the section of I-70 from north of Dorrance to north of Salina was open to traffic. Then in an October 13, 1967 resolution, US-40 was realigned onto the newly opened section I-70.^[6]

Exit numbers are those of I-70 and Kansas Turnpike
