The Sidewalk Highway: 9 feet of preserved 1922 Route 66
The Sidewalk Highway — also called Ribbon Road, the Miami-Afton 9-Foot Road, or simply the Sidewalk — is a 13-mile preserved section of the original 1922 Route 66 alignment between Miami and Afton in Ottawa County. The pavement is a single concrete strip 9 feet wide, the standard width for narrow pre-1929 highway construction in the era when motor vehicles were smaller and traffic volumes were lower. Two-way traffic on a 9-foot strip works only because vehicles must pull onto the shoulder (or the grass) when meeting oncoming traffic — which is precisely how it operated when it was the main highway through this part of Oklahoma in the 1920s.
The road was originally paved in 1922 as part of Oklahoma's earliest state-highway concrete construction program, predating the 1926 designation of Route 66 by four years. When Route 66 was officially designated in 1926, this segment became part of the original Route 66 alignment. In 1937 Route 66 was rerouted onto a wider, faster alignment running parallel to the original, and the 9-foot original was effectively abandoned as a primary route — but never demolished, never paved over, never built around. The road has been quietly drivable as a rural local road for nearly a century since it was bypassed.
What makes the Sidewalk Highway extraordinary is the combination of survival, authenticity, and accessibility. The concrete is the original 1922 pavement (with patches and repairs across the decades but with the original surface intact in most places), the alignment follows the original 1922 route through fields and farmland that look much as they did a century ago, and the road is genuinely drivable by ordinary passenger vehicles at slow speeds. There are only two comparable 9-foot pre-1929 Route 66 alignments preserved in the entire country — this one and a similar narrow strip in New Mexico — and this is the easier of the two to access for most travelers.
