History
The road from Spanish Fork to Springville (leaving the latter on 800 North) was added to the state highway system in 1910, and in the 1920s it became part of SR-1 (US-91). In 1964, when SR-1 was moved to the newly-completed I-15 in the area, the old route between Spanish Fork and Springville became an extension of SR-156 (which had been created in 1962 as a short connection between old and new SR-1 at exit 257). In 1992, because of safety problems at "Maggie's Bend", where SR-156 turned from 800 North onto Childs Road in eastern Spanish Fork, caused in part by superelevation of the curve, 800 North was given to the city and the state took over Childs Road. This split SR-156 in two (with the original section, serving as a spur since 1964, becoming part of the mainline), and the portion on Childs Road and to Springville became a new State Route 51.The junction with US-89 at the north end of SR-51 is a grade separated interchange
