Route descriptionEdit

Highway 599 is a long and isolated road in Northwestern Ontario, starting at the Trans-Canada Highway (Highway 17) near Ignace. It travels through the dense forests and hills of Kenora District and ends in Pickle Lake. It is the longest secondary highway in Ontario, at about 292 km (181 mi) long. It is also the northernmost highway in Ontario maintained by the Ministry of Transportation of Ontario.

The road links up with the Northern Ontario Resource Trail, which used to be a part of Highway 599, and then Highway 808. The Resource Trail is paved for only the first 3 kilometres (1.9 mi) of its length, and is gravel for the rest of its length. It links up with winter roads that travel to isolated communities even farther north, terminating at the northern shore of Windigo Lake.



Highway 599 was initially constructed by the Department of Mines and Forestry in the early 1950s, opening from Savant Lake to Pickle Lake in 1955. In early 1956, that road was assumed by the Department of Highways and incorporated as part of the new secondary highway network, with the designation of Highway 599.[2] Unlike most other secondary highways, it was not possible to access the new highway by car from the rest of the province.[3]

In 1958, construction began to connect the route with Highway 17 near Ignace, working south from Savant Lake. By 1963, Highway 599 was opened to the community of Valora, where it connected with the Ignace–Valora Road. On February 15, the province signed an industrial road agreement, which opened the Ignace–Valora Road to the general public, connecting Highway 599 with the rest of the province. Despite this, work continued on a paved road. In 1963 construction began from the Highway 17 end. The road was completed in the middle by 1966.

In 2017, the provincial government of Ontario pledged support for the construction of a road that would extend Highway 599 to connect Nibinamik, Webequie and the Northern Ontario Ring of Fire to the provincial road network.[4]

Two new Ontario road numbers appear on the province's 1956 official road map which will be ready for distribution next week. The new numbers are the 500 and 600 series and designate hundreds of miles of secondary roads which are wholly maintained by the Highways Department. More than 100 secondary roads will have their own numbers and signs this year. All of these secondary roads were taken into the province's main highways system because they form important connecting links with the King's Highways
