Utah State Route 117

State Route 117 begins on 200 North at the intersection of 200 West in Wales, travelling east for two blocks before turning south on State Street.[1] After less than 1 mile (1.6 km), it leaves the southern end of Wales, the road turns again to the east for approximately 7.4 miles (11.9 km), passing through the town of Chester and crossing US-89 before entering Spring City along 300 North.[4] In Spring City, the route turns north on Main Street, turning to the northeast after about 0.5 miles (0.80 km), continuing this direction for about 3 miles (4.8 km) before terminating at US-89 in Mount Pleasant, directly opposite the Mount Pleasant Airport.[4]

This route was originally part of former State Route 30, a somewhat longer route which was designated as running from Fountain Green on former SR-11 (also known as U.S. Route 89A), south through Freedom and Wales, then east through Chester and Spring City, then northeast to former SR-32 (US-89) in Mount Pleasant.[2]

In 1966, the counties in northern Utah requested that the State Road Commission designate a single route number to run east–west across that part of the state. Since Nevada's portion of the highway was numbered SR 30, Utah selected that number.[3] As a result, in November 1966 the former State Route 30 was renumbered as State Route 117. Route 117 had been freed up four months prior in July when former SR-117 from Bicknell to Boulder was absorbed by former SR-54 (now part of SR-12).[3]

In 1969, the legislature shortened the route by 9.925 miles (15.973 km), moving the western terminus from Fountain Green to Wales. After this change, the route has remained the same through the present day.[3]

The entire route is in Sanpete County.
