The route from
Oklahoma to Rogers was originally designated as
Arkansas State Road B-27 in Arkansas' initial state highway system of 1924. The route was unpaved. Upon redesignation in 1926,
Arkansas Highway 12 was the major east–west route of north Arkansas, running from Oklahoma to
Ash Flat via
Harrison. This Highway 12 was a precursor to
U.S. Route 62 in Arkansas, which supplanted Highway 12 almost entirely in 1930. The portion not replaced by US 62 remained Highway 12, and is very similar to the present-day alignment. The routing was changed slightly in August 2010 when Highway 12 replaced
US 62B in east Rogers. ==See also==
