The portion of K-7 between Leavenworth and the Nebraska state line has been designated the "Glacial Hills Scenic Byway.

"[3] The Kansas Department of Transportation (KDOT) tracks the traffic levels on its highways, and in 2018, they determined that on average the traffic varied from 100 vehicles per day slightly south of the overlap with K-31 to 32200 vehicles per day slightly north of K-10 interchange.

[10] The section of K-7 in Leavenworth from Limit Street north to the end of the overlap with K-92 is maintained by the city.

It continues north, then turns northwest to cross the Kansas River and enter Bonner Springs, where it immediately intersects K-32.

K-7 is one of the original State Highways that was designated in 1927, and at that time extended from the Oklahoma border to US-40 and US-73E west of Kansas City.

[19] In a December 9, 1941 resolution a roughly 2.6 mile section of K-7 was slightly realigned north of Sparks.

[22] In an August 30, 1954 resolution K-7 and US-73 was realigned slightly just north of the Atchison-Leavenworth County line to eliminate two turns.

[23] In an October 19, 1955 resolution it was realigned slightly north of Farlinville to eliminate a sharp curve.

[24] In a November 14, 1956 resolution, K-7 was realigned slightly north of Bonner Springs to meet a new interchange built on US-24, US-40 and US-73.

[25] In a February 25, 1957 resolution a 4.5 mile section of K-7 was realigned slightly west, northeast of Olathe.

Then in a February 11, 1959 resolution the turn at Jones Street was eliminated and it was realigned to go straight north to US-36.

[29] In a February 14, 1968 resolution, a 6.15 mile section of K-7 and US-73 was moved west onto a new alignment south of Atchison.

[31] In a July 19, 1972 resolution K-7 was realigned slightly southeast onto a new alignment or US-169 southwest of Paola.

[40] In a November 3, 2006 resolution K-7 was realigned, slightly south of Girard to eliminated two turns.

The improvements are to support the development of Heartland Logistics, a proposed industrial park on 150 acres at the northwest corner of 43rd and K-7.

The improvements will include additional turn lanes, new detector loops, new traffic signals and grading.
