U.S. Highway 6 in Spanish Fork Canyon was opened to traffic Friday morning about 12 hours after two semitrailer trucks collided.
A Carbon County dispatcher said the highway opened about 5:30 a.m.
The two trucks crashed about 6 p.m. Thursday near the junction with U.S. Highway 89. One truck was hauling a load of gasoline, said Utah Highway Patrol Cpl. Todd Johnson.
