About: Ontario Highway 618

Secondary Highway 618, commonly referred to as Highway 618, is a provincially maintained secondary highway in the Canadian province of Ontario. It connects Olsen Mine and Madsen with the northern terminus of Highway 105 in the town of Red Lake. The 11.7-kilometre (7.3 mi) route was established in 1956, and has remained the same since then. It passes through a remote forested area, and encounters no communities of any significance outside of Red Lake. The route was assumed by the Department of Highways, predecessor to today's Ministry of Transportation of Ontario, in 1956, along with many other secondary highways in Ontario. The route has remained unchanged since then.
