 The route was designated on May 12, 1931, as the road from Tooele at SR-36 northwest to Grantsville at then SR-2 (now SR-138).Since that time, the route had undergone only a handful of minor legislative description changes until April 2009, when the eastern end was realigned.The American Recovery and Reinvestment Act of 2009 provided funds for a new construction project on 1000 North in Tooele, which would provide an alternate route from SR-112 to 600 West.
