History

The route was established in the 1920s, when it began at US 85 at Castle Rock. The route then moved eastward along CR 118 to US 40. In the 1960s, the eastward routing was changed so it follows its current routing. By 1954, the route was paved to Kiowa from US 85 by 1954 and to its entire length by 1972. Following the construction of Interstate 25, the terminus became a business loop of I-25; however, the business loop was deleted in the 1990s, leaving SH 86's terminus at a local road. However, SH 86's terminus was rerouted to US 85 in 2006.
