It has an annual average daily traffic of between 1000 and 1300 and is paved with composite pavement. The highway is not a part of the National Highway System. The route was established around 1967, and has not been changed since.

Route description
The route begins at a diamond interchange with I-135 and US-81. After traveling east for approximately 0.3 mi, it turns south just west of Mentor. From there, it closely parallels the Interstate through about 2 mi of rural farmland before the route ends at a junction with K-4 near I-135/US-81. The route has a total distance of 2.3 mi, all of it in Saline County.

The highway has an annual average daily traffic (the total volume of vehicle traffic of a highway for a year divided by 365 days) of 1,260 over the first 1 mi of the route, and an AADT of 1,069 for the last 1.3 mi of the route. The entire route is paved with composite pavement. K-104 is not a part of the National Highway System.

History
The route was established in 1967 with its current routing in Saline County, with Interstate 135 signed as I-35W. The routing has not been changed. Also, note that K-152 was K-135 at the time.

Original K-104
The original K-104 was designated in 1940 from Pittsburg to Missouri. In 1942, it was proposed to be extended west to a rerouted US 160, which was to be rerouted on a route further south. In 1943, US 160 was not moved to the proposed road, but kept its then-current routing. The part of the proposed road from K-7 to US 69 was designated as a new K-104. The old K-104 was renumbered K-126 to match Missouri. The road from K-7 to US 160 became an extension of K-103. In 1958, K-104 and the extension of K-103 became part of a rerouted US 160, as was planned in 1942. The old route of US 160 became an extension of K-126.
