K-49 (Kansas highway)

K-49 is a 35.354-mile-long (56.897 km) north–south state highway in the U.S. state of Kansas. K-49 begins at U.S. Route 81 (US-81) in Caldwell, and runs north to K-42 in Viola. Along the way, K-49 has a brief overlap with US-160 south of Conway Springs. The majority of the route exists in Sumner County, with only a mile existing in Sedgwick County.

Before state highways were numbered in Kansas, there were auto trails. The southern terminus was part of the former South West Trail and Meridian Highway. K-49 was first designated as a state highway by the Kansas State Highway Commission, now known as the Kansas Department of Transportation, in 1927. At that time it ran from US-81 in Caldwell north to K-42 in Conway Springs. Then, by 1928, K-42 was realigned to a new alignment and at that time K-49 was extended north to Viola.
