U.S. Route 89 in Utah partially coincident with U.S. Route 6 in Utah
I-70 to the Wasatch Front
Although US-89 follows the I-70 freeway from Sevier to Salina, the old alignment can still be driven, and is state-maintained north of Elsinore as SR-258, SR-118 (which overlaps I-70 Business through Richfield), SR-24, and US-50. Both highways stay mainly in the west half of the Sevier River's valley, with the faster I-70/US-89 bypassing the surface road's communities. Just south of Salina, I-70 curves to the east, rising alongside Salina Creek, and US-89 exits into downtown Salina, where it rejoins its pre-freeway alignment. US-50 overlaps US-89 between I-70 and Salina, following I-70 east and a separate alignment northwest from the area; the short Interstate 70 Business also uses this roadway as a business spur from I-70 to the city. North of Salina, US-89 bypasses Redmond (SR-256 follows the former route through the town) and passes through Centerfield to Gunnison, where it meets SR-28 and finally turns away from the Sevier River.At Gunnison, US-89 turns east before curving northeast into the Sanpete Valley, formed by the San Pitch River, a tributary of the Sevier River. Along US-89 in this valley are several small cities: Manti, Ephraim, Mount Pleasant, and Fairview. Between Ephraim and Mount Pleasant, US-89 meets the south end of SR-132 at Pigeon Hollow Junction. SR-132 was formerly US-189, connecting US-89 with US-91 in Nephi. Beyond Fairview, where the scenic SR-31 turns east, US-89 climbs out of the valley, reaching a summit at Hill Top (elevation 6400 feet/2000 m). Thistle Creek parallels the next leg of the highway, descending through a canyon to the junction with US-6 near the ghost town of Thistle, flooded by a landslide in 1983. Thistle Creek and Soldier Creek, paralleled by US-89 and US-6, merge near this junction to form Spanish Fork, which the overlapped routes follow northwest through Spanish Fork Canyon into the Utah Valley at Moark Junction. US-89 splits to the north from US-6 there, skirts the west edge of Mapleton, and merges with SR-51 - the old Arrowhead Trail (US-91) - south of downtown Springville.
