Route 266 is a section of former U.S. Route 66 with termini between Interstate 44 at Springfield and Route 96 west of Halltown. The road runs as a two-lane highway its entire length of 16 miles and is marked as Historic Route 66.

[edit] History

Missouri 266 was originally assigned to a new expressway built through downtown Springfield (specifically, Chestnut Expressway between College Street and Glenstone Avenue). As Interstate 44 was constructed, and US 66 was assigned concurrent with it, the now former US 66 from Springfield to MO 96 was added to MO 266. The westernmost section (which passed through Paris Springs Junction and Spencer) would be turned into county roads. Eventually, Chestnut Expressway would be designated Business Loop I-44, and MO 266 would have its current route.
