History

K-12 was commissioned when the first section of the K-10 freeway was completed from K-7 in Olathe, Kansas to I-435 in Lenexa, Kansas. K-10, at the time, overlapped K-7 from K-12's western terminus in Olathe north to Shawnee Mission Parkway.[1]

When the K-10 freeway segment from Lawrence to Olathe was completed, K-10 was signed for the entire length (both sections) of the expressway. At this time, K-12 was realigned north to replace the former K-10 alignment along the Shawnee Mission Parkway. It followed the parkway from K-7 in Shawnee, then turned north on Merriam Drive in Merriam, which follows into Kansas City, Kansas. Merriam Lane turns into Southwest Boulevard near US-169, and K-12 ended not far east at the Missouri state line.[2]

Since K-12 existed entirely within the city limits of the cities it traverses, it was turned back to the cities in 1987 according to KDOT policy.[3]
