State Route 257 is a highway in central Utah that runs from the junction of SR-21 in Milford to US-6/US-50 sixty-nine miles (111 kilometers) to the north in Hinckley.

Route description

From its southern terminus in Beaver County, SR-257 generally north until Black Rock, where it makes a turn to the northwest. It stays north-northwest until the northern terminus of the route, located in Millard County. Most of the route is paralleled by the Lynndyl Subdivision of the Union Pacific Railroad.


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.[2] 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.[3] 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.[4] With the deletion of SR-140 in 1969, SR-257 assumed its current extent, replacing the north–south piece of SR-140.[5]
