 The state legislature created State Route 111 in 1931, running west from SR-71 in Draper to SR-68 in Riverton.State Route 159, added in 1933, continued west from Riverton through Herriman to Lark and then turned north along the Oquirrh foothills to U.S. Route 50 (US-50), present-day SR-171 (3500 South), near Magna.The two routes were combined as SR-111 in 1945, and in 1957 the east end was extended north along 700 East, which had been SR-71, to 7700 South north of Sandy, only to be truncated back to Draper in 1959 when SR-71 was again restored there.
