State Route 102 (SR-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.
The route starts on SR-83 east of Lampo Junction travelling northeast. After about 2 miles (3.2 km), 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.
