History of Secondary Highway 672:
Secondary Highway 672 is a local highway which provides a connection between Highway 66 and Highway 101 in the District of Timiskaming northeast of Kirkland Lake. It is one of Ontario's newest highways. In the early 1990s, the Harker-Holloway Road was assumed as a new provincial highway. In February 1990, a Preliminary Assumption Plan was prepared by the Ministry of Transportation of Ontario (MTO) which showed the planned assumption of the Harker-Holloway Road as a new Secondary Highway. The Preliminary Assumption Plan was registered on March 15, 1990, and the route was formally designated as Secondary Highway 672 by an Order-in-Council dated April 4, 1990. The highway is paved for its entire length. Unless posted otherwise, the speed limit on Highway 672 is 80 km/h (50 mph). There are no services available on this highway.
