Except for the portion between Palisade and US 40, the road was completely paved by 1956—a road connecting just south of Palisade directly to Carlin (approximating today's alignment of the northernmost reaches of SR 278) was also paved by this time. The Eureka–Carlin road portion of SR 20 was renumbered as part of State Route 51 by 1965. The Eureka–Carlin road remained unchanged for several years after being renumbered to SR 51. However, the
