 However, the portion across the Traverse Mountains between SR-111 (12300 South) in Draper and Alpine was never built, and was removed from the state highway system in 1935; at the same time, the southern piece from Alpine to American Fork was renumbered SR-74.In 1957, most of SR-71 was moved west two blocks to 700 East, the south end was truncated to 7700 South north of Sandy (replaced by an extension of SR-111), and the north end was extended to SR-181 (South Temple Street).This change was partially reverted in 1959, when the south end was extended back to Draper over what had just become SR-111.
