Utah State Route 186 Utah State Route 186 State Route 186 (SR-186) is a state highway entirely within Salt Lake City, capital of the U.S. state of Utah. It forms a quarter-beltway connecting US-89 and I-15 leading north from Salt Lake City to I-80 leading east; as such, it effectively forms the missing (non-freeway) quarter of the I-215 belt route around the city, though it does not directly connect to I-215 at the north end. Despite this beltway role, the route passes through downtown Salt Lake City because downtown is built right up to the northern mountains surrounding City Creek Canyon. The portion of
Utah State Route 139 extended east past US-6 and north through Spring Glen to meet State Route 157, eight years after SR-157 had been extended north from Spring Glen to Helper. The route was significantly shortened in 1975, with the west of US-6 being deleted from the state highway system, leaving SR-139 as a short connector between US-6 and SR-157. In 1978, SR-139 was lengthened by when reconstruction of US-6 in the area necessitated moving its intersection with SR-139 southward, resulting in the current alignment.
