sr-57 begins at the junction with sr-10 near the hunter power plant, three miles (5 km) southwest of castle dale, and runs almost straight north for almost four miles (6 km) until it nears orangeville. it then bypasses orangeville heading northwest. at the junction of sr-10 it turns north again and then moves in a north-northwest direction until it reaches its terminus at the southern edge of the wilberg mine, about northwest of orangeville (the wilberg mine is the location of the fire that took twenty seven lives in 1984).
