K-9 K-11

K-10 is a 38-mile (61 km) state highway in the U.S. state of Kansas. It was originally designated in 1929. It is mostly a controlled-access freeway, linking Lawrence to Lenexa. It provides an important toll-free alternate route to Interstate 70 (the Kansas Turnpike). Several scenes for the controversial[according to whom?] TV-movie The Day After were filmed on the highway in 1982 portraying a mass exodus evacuating the Kansas City area on I-70.

Route description[edit]

The highway's western end begins as a two-lane highway at I-70 exit 197 just west of Lawrence. It partially bypasses the city to the south to U.S. Route 59, providing access to Clinton Lake. K-10 turns north on US-59 for about 1 12 miles (2.4 km) (overlapping it) before turning east on 23rd Street. After exiting Lawrence east-bound, it becomes a freeway, passing through the city of Eudora, and then the cities of De Soto and Olathe, suburbs of Kansas City. It then terminates at an interchange with Interstate 435 in Lenexa. The eastern terminus is being reconstructed to provide a direct link to I-35. In Johnson County, the road is called the Governor John Anderson, Jr. Highway.


K-10 originally extended west of Lawrence to Herington, via Alta Vista, Alma, and Topeka. In 1956 the portion between Topeka and K-99 near Alma was designated as US-40 in preparation for upgrading this stretch to Interstate standards (for I-70). The segment between Alta Vista and Herington was redesignated as K-4 and K-10 was truncated eastward to Lawrence.

The process of upgrading K-10 to a freeway was begun in 1974. The first section completed was the section from De Soto to the junction with K-7, opening on November 8, 1976. The freeway was finally completed on December 18, 1984, when the stretch from K-7 to I-435 was completed.[1] The old two-lane roadbed of K-10 was turned over to the counties to use as a secondary route. In Douglas County it became CR 442, although many of the locals, especially in Eudora, commonly refer to it as Old K-10.

The portion of K-10 between the Edgerton Road exit and the De Soto interchange at former K-285 (now Lexington Avenue) was used in the movie The Day After and, for the purposes of the film, was temporarily redesignated Interstate 70.

South Lawrence Trafficway[edit]

In the early 1970s traffic studies of K-10 determined a bypass around the west and south sides of Lawrence was necessary, and the Kansas Department of Transportation commenced due diligence on the bypass project. The bypass of the west side of Lawrence was completed in November 1996. Prior to the opening of the Trafficway, K-10 had ended at the junction of US-40 and US-59 in Lawrence. Completion of the eastern leg of the Trafficway was delayed for nearly three decades by lawsuits from environmentalist groups and Haskell University, as the planned route takes the highway through the Haskell-Baker Wetlands. The lawsuits delayed the project for more than thirty years. In 2014, the lawsuits were settled. Construction began in March 2014 and was anticipated to be completed by Fall 2016 before Thanksgiving.[2] The ribbon cutting ceremony for the east leg of the South Lawrence Trafficway, signaling the opening of the new stretch of highway to traffic, will occur November 4, 2016.
