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.

However, the 650 North roadway progresses straight for about 300 ft (91 m), passing a gated fence on the north side of the highway leading to a rail stub, and the dead-end of Aspen Avenue, before reaching the entrance to the Falcon Hill National Aerospace Research Park, just outside Hill Air Force Base.

[10] The measurement point for the traffic counts is at the eastern terminus of SR-103, the entrance to the Falcon Hill National Aerospace Research Park.

The SR-103 designation was rewritten in the Utah Code as a highway following Harrison Street in the city of Ogden.

The SR-103 designation was soon rewritten in the Utah Code as an access road to Hill Air Force Base on April 19, 1965.

In 1964, a year prior to designation, a 27-foot-long (8.2 m) concrete culvert bridge was constructed over the Davis Weber Canal.

[14] The two bridges for I-15's southbound and northbound roadways were built in 1966 and are two 159-foot-long (48.5 m) concrete continuous tee beam overpasses.

[17] The most recent change to SR-103 came in March 2019, when the Utah State Legislature approved a slight truncation of the east end of the route.

The segment of 650 North between I-15 and the base gate was removed from the legal definition of SR-103 at that time, bringing the eastern terminus back to the I-15 interchange.
