History of Secondary Highway 585:

Secondary Highway 585 is a local highway in the District of Thunder Bay that provides access from Highway 11 & Highway 17 in Nipigon northerly to the Pine Portage Hydro-Electric Generating Station. The proposed route of Highway 585 was first depicted on a Preliminary Route Plan prepared by the Department of Highways of Ontario (DHO) in May 1956. Highway 585 was 23 miles in length and followed an existing Hydro-Electric Power Commission of Ontario (HEPC) road which had been built decades earlier to service the Pine Portage and Cameron Falls hydro developments along the Nipigon River. Highway 585 was designated as a Secondary Highway by an Order-in-Council dated May 9, 1956. The highway was gravel-surfaced at first and was first shown with a completely paved surface on the 1974 Edition of the Ontario Official Road Map. The route of Highway 585 has not changed since it was first designated in 1956. Unless posted otherwise, the speed limit on Highway 585 is 80 km/h (50 mph). There are no services available along Highway 585 itself, but services can be found along Highway 11 & Highway 17 in Nipigon.
