'''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.
==Route description== thumb|right|Western terminus at SR-83 The route starts on SR-83 east of Lampo Junction travelling northeast. After about {{convert|2|mi|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.<ref name="reference"/><ref name="Google Maps">{{Google maps|url=https://maps.google.com/maps?ie=UTF8&ll=41.6665,-112.214699&spn=0.123362,0.270882&z=12|access-date=2009-10-05}}</ref>
==History== {{see also|Utah State Route 30#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 (this stretch of road was formerly part of SR-3).<ref name="resolution"/>
thumb|Signage used from 1966 to 1977 on SR-30 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.<ref name="resolution"/><ref name="resolution 30">{{cite web|title=State Route 30 Resolutions|publisher=Utah Department of Transportation|url=http://www.udot.utah.gov/main/uconowner.gf?n=200609131100101|access-date=2009-10-05|date=November 2008}}</ref>
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.<ref name="resolution"/>
