State Route 16 (SR-16) is a state highway in northeastern Utah, running for 29.359miles in Rich County from the Wyoming state line near Woodruff to Sage Creek Junction. It serves as part of a road from Evanston, Wyoming to Jackson Hole, Wyoming.
SR-16 begins at the Wyoming state line south of Woodruff, as an extension of WYO 89, and heads northwest 10miles to Woodruff, where it turns north through the town center.
SR-16 then continues north 10miles to Randolph, running through the town center. North of Randolph, it runs generally north-northeast 9miles to end at an intersection with SR-30 at Sage Creek Junction.
A 1921 law added the portion of the road from Evanston, Wyoming to Montpelier, Idaho in Utah to the state highway system, as well as the branch towards Kemmerer, Wyoming.[1] The State Road Commission assigned the State Route 3 designation to the highway that decade,[2] and in 1927 the legislature officially adopted the number for the main route and the spur.[3] The spur was split off as SR-51 in 1931,[4] but the remainder stayed as SR-3 until 1962, when it was renumbered SR-16. In the 1977 renumbering, only the section south of Sage Creek Junction remained, as the rest became SR-30 (signed since 1966) and US-89 (signed since the 1930s).[5]
