K-192 (Kansas highway)

K-192 is a 16.241 mi east–west state highway in the U.S. state of Kansas. K-192's western terminus is at U.S. Route 59 (US-59) and K-16 west-northwest of Winchester and the eastern terminus is at US-73 and K-7 west-northwest of Leavenworth. K-192 travels mostly through rural land but does pass through the cities of Winchester and Easton.

Before state highways were numbered in Kansas there were auto trails. The former Corn Belt Route and South West Trail closely followed the highways western terminus. The former George Washington National Highway and King of Trails followed the highways eastern terminus. K-192 was first designated a state highway on January 4, 1939. In 1964, the western terminus was shortened slightly when a new alignment of US-59 was built, and then in 1999, the eastern terminus was shortened when US-73 was moved to a new alignment.

Route description
The Kansas Department of Transportation (KDOT) tracks the traffic levels on its highways, and in 2017, they determined that on average the traffic varied from 625 vehicles per day slightly east of Winchester to 2280 vehicles per day near the eastern terminus. K-192 is not included in the National Highway System, which is a system of highways important to the nation's defense, economy, and mobility. K-192 does connect to the National Highway System at its eastern and western terminus. The majority of the route is paved with partial design bituminous pavement except for the segment within the Easton city limits, which is full design bituminous pavement.

History
Before state highways were numbered in Kansas there were auto trails, which were an informal network of marked routes that existed in the United States and Canada in the early part of the 20th century. The former Corn Belt Route and South West Trail closely followed the highways western terminus. The former George Washington National Highway and King of Trails followed the highways eastern terminus.

K-192 was first designated a state highway on January 4, 1939, by the State Highway Commission of Kansas, now known as KDOT. On August 12, 1964, the western terminus of K-192 was truncated 1.124 mi when US-59 was moved onto a new alignment slightly east. In a March 9, 1990 resolution, the eastern terminus of K-192 was truncated 0.379 mi when US-73 and K-7 were moved onto a new alignment between Leavenworth and Lowemont.
