State Line Road

Not to be confused with State Line Avenue, a similar road in the Texarkana metropolitan area.

State Line Road is a major north–south street in the Kansas City Metropolitan Area that runs along the Kansas–Missouri state line. It connects U.S. Highway 56 in the north with Route 150 in the south. Cities along the road include Kansas City, Missouri, Kansas City, Kansas, and several smaller communities in Kansas such as Leawood, Mission Hills, Prairie Village, and Westwood Hills.

For northern portions of the road, the Missouri–Kansas state line bisects the roadway. Consequently for these portions of the road, northbound traffic is in Missouri while southbound traffic is in Kansas. For southern portions of the road, the entire road is in Missouri.

State Line Road is home to

• the home and freighting office of Alexander Majors, a building on the National Register of Historic Places and located at 8145 State Line Road.
• several schools on the Missouri side, such as Barstow, Pembroke Hill and Rockhurst High School
• Ward Parkway Center at 8600 Ward Parkway

In 2001 Leawood promoted State Line Road as "The State Line Link."
