State Route 78 (SR-78) is a 9.418-mile-long (15.157 km)state highway in the U.S. state ofUtah that serves as a connector from the town ofLevan andSR-28 toInterstate 15 (I-15) and theChicken Creek Reservoir. The route was formed in 1977 and has preserved its initial state since then.
The road begins at adiamond interchange withI-15 at exit 207. From that point, the route heads northwest as a two-lane undivided highway, running almost parallel to I-15 in the west and Chicken Creek Reservoir in the east. Once the route passes the reservoir, it eventually turns north-northwesterly until reaching the intersection of a local road, where it turns east. The route enters Levan as 100 North and soon terminates atSR-28, the main street of Levan.[2]
The east–west portion of SR-78 between Levan and Elevator Road is a part of theNational Highway System.[3]
In 1975, asInterstate 15 was being constructed in the area,State Route 163 was designated along the old alignment ofUS-91 from I-15 atMills Junction toSR-28 inLevan.[4] Since this route shared a number withU.S. Route 163 in southern Utah, it was renumbered to SR-78 in the1977 Utah state route renumbering. The only change that has occurred to the route since then was a change to the legal definition in 1987, making it more detailed.[5]
The entire route is inJuab County.
