State Route 103 (SR-103) is a 0.225-mile-long (362 m) urban minor arterial state highway in the U.S. state of Utah. It branches off from SR-126 (Main Street) in downtown Clearfield and extends east to Interstate 15 (I-15), with the roadway continuing to the Falcon Hill National Aerospace Research Park, just outside Hill Air Force Base. The entire route is located in Davis County and was formed in 1965 coinciding with the construction of I-15.
The western terminus, in a stretch of fourteen years from its inception, has gone from SR-1 in 1965, to SR-106 in 1967, to SR-84 in 1969, and SR-126 in 1979. In 1979, the moniker of the roadway for SR-103 was changed from 600 North to 650 North. SR-103 is one of four Utah state highways that connect to Hill Air Force Base, the others being SR-97, SR-168, and SR-232. Only SR-168 has a lower average daily traffic count, with roughly 1,000 vehicles-per-day traveling along the highway compared to SR-103's approximately 16,000 vehicles-per-day. The highway has been largely unchanged since its formation, except for the addition of traffic lights at the on and off ramps for I-15, and a slight truncation of the east end from the air force base gate to I-15.
