Route description

History
The northernmost piece of SR-257 became a state highway in 1933 as part of State Route 140, a short connection from SR-27 (now US-6) near Hinckley south to Deseret and east via Oasis to SR-26 (now US-50) at Harding. The remainder was not created until 1955, when the state legislature added the road between SR-21 in Milford and SR-140 at Deseret to the state highway system as SR-257. A short loop through downtown Hinckley, heading west from SR-140 on 2500 South and north on Main Street to SR-27, was added as State Route 240 in 1966 but dropped from the state highway system in 1969. With the deletion of SR-140 in 1969, SR-257 assumed its current extent, replacing the north–south piece of SR-140.
