State Route 45 (SR-45) is a state highway in the U.S. state of Utah. It runs from Dragon Road south of Bonanza in Uintah County north to US-40 in Naples, south of Vernal. The route spans 40.03 miles (64.42 km) south–north.
The route was added to the state highway system in 1925 and numbered in 1927, originally running from US-40 southeast to the Colorado state line. Subsequently, the highway was moved to a new road in 1943, truncated to Bonanza in 1968, and again moved and extended in 1982.
The route begins at the intersection of Dragon Road south of Bonanza as a two-lane undivided road. From there, it heads north-northwest and passes through Bonanza. Past the settlement, the route goes in a northwest direction for the rest of its path and enters in Naples as 1500 East, where it terminates at US-40.
The road now known as Snake John Reef Road, running southeast from SR-6 (US-40) to the state line, was added to the state highway system in 1925 and numbered SR-45 in 1927. Across the state line, this connected with the original alignment of State Highway 64. In 1943, the route was shifted west, now following Old Bonanza Highway from US-40 south to Bonanza. An extension south to the state line via Dragon was added in 1945, with an unnumbered unimproved road (briefly State Highway 395) continuing over Baxter Pass to US 50 near Mack, Colorado. The same year, State Route 207 was created as a short spur, now Bitter Creek Road, to Rainbow. The State Road Commission removed these 1945 additions from the state highway system in 1968, cutting SR-45 back to Bonanza.
