The Sidewalk Highway (also called the Ribbon Road), is a 15-mile section of original route 66 constructed in 1921-1922, that is only 9-feet wide.

It ran between Miami and Afton, and included 90-degree curves. According to sources, the state of Oklahoma (being a fairly new state), was short on funds and built the narrow roadway due to the lack of funding. In 1926, this stretch became part of Route 66, and was in use until 1937 when a new alignment was built.
