Utah State Route 124 (SR-124) is a state highway in the U.S. state of Utah. Spanning {{convert|7.9|mi|km}}, it connects the cities of Sunnyside and East Carbon in Carbon County with Horse Canyon Mine in Emery County.
Route description
State Route 124 begins near Horse Canyon Mine along the Book Cliffs in northern Emery County. It starts out traveling west, but soon curves to the north as it crosses the county line into Carbon County. The route continues north along the base of the Book Cliffs, through Columbia Junction just west of Columbia, and finally takes a jog to the west just before ending at its intersection with SR-123 in East Carbon.{{Google Maps|url=https://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=columbia,+ut&aq=&sll=39.488012,-110.393801&sspn=0.042924,0.076733&ie=UTF8&hq=&hnear=Columbia,+East+Carbon,+Carbon,+Utah&ll=39.521522,-110.394745&spn=0.085806,0.153465&z=13}}
History
The road from Sunnyside south to Columbia (along with the road from Sunnyside west to Sunnyside Junction) was designated as SR-124 in 1931,{{cite UTSR law|year=1931|chapter=|quote=(124) From Sunnyside junction easterly via Sunnyside to Columbia.}} and renumbered to SR-123 in 1933.{{cite UTSR law|year=1933|chapter=30|quote=(123) From Sunnyside Junction easterly via Sunnyside to Columbia.
}} In 1935, the portion from Sunnyside to Columbia was split off{{cite UTSR law|year=1935|chapter=|quote=Route 123. From Sunnyside Junction on route 8 easterly to Sunnyside.}} and designated as SR-124, which was extended south to Horse Canyon Mine in 1945.{{cite UTSR law|year=1945|chapter=|quote=Route 124. From route 123 southerly via Columbia to Horse Creek coal mine.}} Since then, only minor legal description changes have occurred such as reversing the described direction from southerly to northerly, and replacing "via Columbia" with "through Columbia Junction" after the town of Columbia became part of newly incorporated East Carbon.
