Utah State Route 102


State Route 102 is a state highway in the U.S. state of Utah that connects Tremonton with I-84, SR-83, and the towns of Deweyville, Bothwell, Thatcher, Penrose, and Thiokol's facility in Box Elder County.

Route description

The route starts on SR-83 east of Lampo Junction travelling northeast. After about, the route starts to "stairstep", alternately going north and east through Penrose and Thatcher, before settling on an easterly direction through Bothwell. Soon after, the route intersects I-84 at Bothwell Junction, passes under I-15, passes through Tremonton and Haws Corner Junction and ending at SR-38 in Deweyville at the base of the Wellsville Mountains.

History

SR-102 was originally designated in 1931 as the road from Deweyville to Haws Corner. In 1969, the route was extended westward through Tremonton to SR-83 east of Lampo Junction.
In 1966, the counties in northern Utah requested that the State Road Commission designate a single route number to run east-west across that part of the state. This route overlapped SR-102 between Deweyville and I-84. For this new route, the number SR-30 was selected, but there were no legislative description changes of the highways. Instead, the old route numbers were kept and marked on small, rectangular signs below the SR-30 shields.
In the 1977 renumbering, the legislative description of this new route was changed to SR-30, resulting in SR-102's eastern terminus being moved to I-84. In 1989, the commission resolved that, once I-15 was completed north of Tremonton, SR-30 would be rerouted to replace SR-129, with SR-102 being extended back to Deweyville.
