About: Ontario Highway 599

Secondary Highway 599, commonly referred to as Highway 599, is a provincially maintained secondary highway in the Canadian province of Ontario. The 291.0 km (180.8 mi) route connects Highway 17 near Ignace with the remote northern community of Pickle Lake; its terminus at Pickle Lake marks the northernmost point on the provincial highway system. Highway 599 was first assigned in 1956 between Savant Lake and Pickle Lake, although it did not connect with the rest of the provincial highway system at the time. Construction to link it with Highway 17 in Ignace took place between 1958 and 1966. The northern end of Highway 599 is one of two possible starting points for a road to the Ring of Fire mineral deposits, the other being Highway 584 in Nakina.
