History

US 400 was first established on December 1, 1994, and at that time ran from the east end of the US-50 and US-83 overlap, eastward to the east county line of Cherokee County, Kansas. In a May 3, 1995 resolution, it was approved to move US-400 and K-96 to a new alignment between northwest of Fredonia and Neodesha, at that time the overlap with K-47 was removed. In a December 3, 1998 resolution, it was approved to truncate K-96 to end at US-400 by Wichita.

U.S. Route 154

A section of U.S. 400 that ran from Dodge City to Mullinville, Kansas was U.S. Route 154 from 1926 to 1982. It later became K-154 before becoming part of U.S. 400. Construction on the first section of the East Kellogg improvement project started in August 2015. The project included a redesigned intersection with Webb Road and widened US-54 and US-400 from four lanes to six lanes from Webb Road to Greenwich Road. Construction on a second project began in 2016, to continue widening the highway to a six-lane freeway between Greenwich Road and K-96. Also new bridges will be built over I-35/KTA, new ramps will be constructed from southbound I-35/KTA to westbound US-54/US-400 and from eastbound US-54/US-400 to both northbound and southbound I-35/KTA. In addition, two-lane one way frontage roads on each side of the freeway will be built. Construction for both projects should be completed by late 2021. A two-mile section of the new highway, from Eastern Street to the K-96 junction, opened on November 21, 2019. On April 16, 2020, vandals damaged an estimated $50,000 worth of construction equipment, which included a bulldozer, excavator and an off-road vehicle.
