History

State Route 139 was originally established in 1933 as the road from former Route 8 (now US-6) west to Consumers, a distance of about 13.3 miles (21.4 km). In 1969, SR-139 was 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 13.3 miles (21.4 km) 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 0.1 mile (0.160934 km) when reconstruction of US-6 in the area necessitated moving its intersection with SR-139 southward, resulting in the current alignment.
