Utah State Route 100 (SR-100) is astate highway in the U.S. state ofUtah. Located entirely inMillard County, it connects the city ofFillmore withFlowell and theghost town ofMcCornick over a distance of 16.9 miles (27.2 km).
The route begins as 400 North atSR-99 (Main Street) inFillmore. From here, it travels west out of town, crosses overI-15. After 4.6 miles (7.4 km), the route turns north and continues through rural Millard County for about 12.3 miles (19.8 km) until it ends atUS-50.[1][3]
The course of this route trends generally from southeast to northwest. Although there is not an abundance of directional banner signage on the route, what few banners that exist indicate that SR-100 is an east-west route. Despite this, the route description and mileposts begin in Fillmore as they would if this were a north-south route.
SR-100 was originally established in 1935 as connectingFillmore atSR-1 (Main Street) andFlowell. The construction ofI-15 through the area resulted in the old alignment of the route along 100 North to be severed in two by the interstate, so in 1965, the route was moved north three blocks to its current alignment along 400 North because of the proposed underpass on that street.[2]
In 1969, the 12.6 miles (20.3 km) from near Flowell northward toUS-50 was transferred to the route, resulting in its current length and alignment.[2]
The entire route is inMillard County.
