designated Blue Lake Road as Highway 647, effective December 20, 1963. The route of Highway 647 was initially gravel-surfaced for its entire length, but the
entire route is now paved. Unless posted otherwise, the speed limit on Highway 647 is 80 km/h (50 mph). There are no services available on this highway other
