Historic Southeast Endpoint: US 56/K-96 east of Great Bend

Historic Northwest Endpoint: US 281 North of Great Bend

Historic County Served: Barton


A spur from US 50N on the east side of Great Bend to US 281 on the north side of Great Bend was established in a June 22, 1949 Highway Commission resolution. It was eventually signed as an alternate route of US 281. It was withdrawn sometime between 1981 and 1984 and turned back to Great Bend, as the city had annexed the entire stretch of the roadway.

US 283

Length: 217.084 miles

South Endpoint: Oklahoma State Line south of Englewood

North Endpoint: Nebraska State Line north of Norton

Counties Served: Clark, Ford, Hodgeman, Ness, Trego, Graham, Norton


US 283 Spur

Historic South Endpoint: I-70/US 40 exit 128

Historic North Endpoint: US 283/Old US 40 at 13th and Barclay Ave., WaKeeney.

Historic County Served: Trego


A spur of US 283 in WaKeeney along 13th Street was designated in a February 26, 1958 Highway Commission Resolution in conjunction with the designation of I-70 through Trego County. The new spur ran from Barclay Avenue south to I-70.

The State Highway Commission never sought the inclusion of this route, among others, as part of the US Highway system. After the Highway Commission was reformed into the Kansas Department of Transportation, KDOT submitted this route for approval as a Business Loop of I-70 and a Alternate route of US 40. AASHTO rejected the I-70 business loop request and approved the US 40 request as a business loop at their June 1979 meeting. KDOT implemented the change of this route to US 40B in an April 1981.

Despite the designation, the route may have not been signed as a spur of US 283. Photos from Michael Summa posted at Steve Alpert’s Alps’ Roads indicate that the US 283 spur was marked as a Business loop of I-70 as late as 1986.


Length: 5.618 miles

West Endpoint: Junction K-14 10 Miles North of Lincoln

East Endpoint: West City Limits of Barnard

County Served: Lincoln

AADT (2019): 165 (18.2% truck)


A spur from K-14 to the city of Barnard in Lincoln County was first designated in a March 22, 1961 Highway Commission resolution, then withdrawn in a March 29, 1967 resolution. The first withdrawal resolution showed the route designated as K-237. It was re-instituted with a proposed designation of K-225 in a November 23, 1972 resolution. As K-225 was already in use, the designation was changed to K-284 in a January 18, 1972 resolution. The new number was assigned in sequence. It was slated to be withdrawn again in a May 9, 1973 resolution; however, after a public meeting, the withdrawal of the route never occurred.


Length: 0.218 miles

South Endpoint: K-10 south of Desoto.

North Endpoint: South City Limits of DeSoto.

Historic County Served: Johnson


K-285 was designated in 1972 from part of the former alignment of K-10 as a spur from the new freeway alignment into DeSoto. The number was assigned in sequence, the last K- numbered highway to be established in this manner.

The K-10 freeway east of DeSoto was opened on November 8, 1976, establishing the spur. Within a couple of months, the City of DeSoto had annexed land along the spur. KDOT subsequently issued a resolution, dated January 26, 1977, withdrawing the annexed part of K-285 and turning it back to DeSoto. The resolution also contained a provision stating that any future segments of the spur that were annexed would automatically be withdrawn and turned back.

DeSoto finally annexed out past K-10 in the late 1990s. KDOT sent notice to the city of DeSoto that K-285 would be turned back effective November 21, 1997.


Length: approx. 0.75 mile

Historic West Endpoint: K-92 east of Springdale

Historic East Endpoint: Junction K-92 east of Springdale

Historic County Served: Leavenworth


In 1945, the State Highway Commission started a project to restore and preserve a the last covered bridge in Kansas over Stranger Creek near Springdale. The bridge, and the road connecting it to K-92 on both sides of the bridge, were made a state highway. The highway number was derived from K-92.

On September 23, 1958, lightning struck the bridge, burning it. With the bridge destroyed, the Highway Commission withdrew K-292 in 1960. The bridge approaches were subsequently abandoned.


Length: 15.668 miles

Historic Northwest Endpoint: Junction K-96 east of Mount Hope

Historic Southeast Endpoint: Junction K-96 near Maize

Historic County Served: Sedgwick


K-296 was established in a May 5, 1965 Highway commission resolution in conjunction with a new alignment of K-96 between Mount Hope and Wichita. K-296 is the original alignment of K-96 between Mount Hope and Maize. The number is derived from K-96.

K-296 was withdrawn in a October 16, 1996 KDOT resolution and turned back to Sedgwick County.

In 1987, KDOT submitted a request for the previously unnumbered section of the Kansas Turnpike between Emporia and Topeka to be included in the Interstate highway system as I-335. The request was made to allow the speed limit on this stretch of the highway to be raised from 55 mph to 65 mph. The request was approved by AASHTO at their December 5, 1987 meeting.

US 340

Proposed West Endpoint: Colorado state line west of Weskan

Proposed East Endpoint: Junction US 40 in Manhattan

Proposed Counties Served:
Wallace, Logan, Gove, Trego, Ellis, Russell, Ellsworth, Saline, Dickinson, Geary, Riley


In the original 1926 US highway proposal, US 340 would have followed the Golden Belt highway from Manhattan west, while US 40 would have followed the Midland Trail. The towns along the Golden Belt protested, claiming that the Midland Trail got the nod because it passes through the hometown of Highway Commission Davidson. A meeting was held with the Victory Highway cities on December 18, 1925, leading to a compromise where the Midland Trail became US 40N, while the Victory became US 40S.

In 1991, KDOT approved plans for a two-lane bypass of Winfield. The route was numbered as a derivative of US 160. The bypass was completed in the fall of 1996. K-360 is the most recent highway created as a result of new construction instead of a re-designation of an existing route

The general routing for I-435 was submitted to the Federal Government as a component of Kansas’s initial part of the Interstate Highway System. It was approved by AASHO on November 10, 1958 and designated in a November 18,1959 Highway Commission Resolution. Intially, I-435 consisted of a half-beltway between I-35 near Lenexa and I-35 northeast of Kansas City, Missouri. The section between I-35 and US 69 at Metcalf Avenue was open by 1965, with the portion between Metcalf and State Line Road completed by 1969.

Eventually, an extension of I-435 into a full beltway was proposed. The Kansas portion of the extension was designated in a September 29, 1972 Highway Commission resolution. Construction on the west let of I-435 began in earnest in the 1980s. I-435 was completed from Midland Drive to K-32 by 1981, from I-35 to Midland Drive and from K-32 to Kansas Avenue by 1985, from Kansas Avenue to Leavenworth Road by 1986, and from Leavenworth Road to the Missouri River by 1987.

The general routing for I-635 was submitted to the Federal Government as a component of Kansas’s initial part of the Interstate Highway System. It was approved by AASHO on November 10, 1958. The portion of I-635 bwtween I-35 in Overland Park and US 24 in Kansas City was established in a August 9, 1961 Highway Commission resolution.

Initially, I-635 was slated to turn east near Leavenworth Road and tie in to the Fairfax Bridge. By 1968, the proposed I-635 was moved onto a new bridge, though the spur to the Fairfax District remained as a non-interstate freeway, K-6.

The first section of I-635 to open was between US 24 at State Avenue and K-5 at Leavenworth Road, which opened on December 7, 1970. The segment from I-35 to Metropolitan Avenue was completed by 1972. The segments from Metropolitan to Kansas Avenue and from Leavenworth Road to the Missouri River were completed by 1975. The final section from Kansas Avenue to State Avenue, including the junction with I-70, was opened on December 1, 1976.

Although I-670 was submitted as a component of Kansas’s initial part of the Interstate Highway System, it was not included in the initial Interstate Highway System, but was added to the system on October 15, 1964. The Highway Commission submitted to AASHO in 1970.

Construction on I-670 was not completed until 1991.
