 SR-228 received its designation in 1981 when the existing local roads were granted state highway status by the Utah State Legislature.Originally, the route began with the current spur (Cemetery Road) and then headed northeast along Main Street for the remainder of the current route (including the portion on Silver Reef Road), but did not include any portion of South Main Street south of Cemetery Road.However, sometime prior to 1998, the official designation had been amended to reflect the current route.
