Highway 17 (Ontario)
Encyclopedia
King's Highway 17, more commonly known as Highway 17, is a provincially maintained highway and the primary route of the Trans-Canada Highway
Trans-Canada Highway

 with a peak length of about 2180 km (1,354.6 mi). However, a section of Highway 17 "disappeared" when the Ottawa section of it was upgraded to the freeway Highway 417 in 1971. Highway 17 was not re-routed through Ottawa, nor did it share numbering with Highway 417 to rectify the discontinuity, even though Highway 417 formed a direct link between the western and eastern sections of Highway 17. However, from East Hawkesbury to Ottawa, Highway 17 retained the Trans-Canada Highway routing and signs until it met up again and merged with Highway 417 until 1997, when Highway 17 through Ottawa was downloaded. The Trans-Canada Highway designation now extends along all of Highway 417.

History

The route which would become Highway 17 was first designated as a provincial highway on February 26, 1920, when two separate highways were added to the system. The first travelled between Ottawa and Pembroke, while the second travelled between Ottawa and Point Fortune
Pointe-Fortune, Quebec
Pointe-Fortune is a village in southwestern Quebec on the Ottawa River in Vaudreuil-Soulanges northwest of Montreal. The population as of the Canada 2006 Census was 507.-Population:Population trend-Language:...

 at the Ontario–Quebec border. Both these routes became known as Highway 17 in the summer of 1925.
By 1930, a road existed between Pembroke and Sault Saint Marie, although it was not part of Highway 17 at the time.
This road was constructed beginning in 1926 with the signing of the Department of Northern Development (DND) Act. On April 1, 1937, the DND was absorbed into the Department of Highways, and the road west of Pembroke became an extension of Highway 17.

The portion of Highway 17 over the top of Lake Superior was constructed in the late 1950s as a result of the Trans-Canada Highway Act. Amongst some of the most difficult terrain encountered in Canada, engineers blasted 2,730,000 cubic yards of rock, removed 7,825,000 cubic yards of earth, and cleared 6.97 square kilometres (1,722.3 acre) of forest in order to bridge the 266 kilometres (165.3 mi) of wilderness known as "the Gap". The Gap was completed and opened to traffic on September 17, 1960, uniting the two segments and completing the route of Highway 17 from the Manitoba border to the Quebec border.
The last gravel stretch of Hwy 17 was located west of Ignace

 in Ottawa called for the creation of numerous parkways and divided highways through the burgeoning city. One of these, known as The Queensway, was a grade-separated freeway that would bypass Highway 17. This freeway was gradually constructed throughout the 1960s.

On April 1, 1997, the Ministry of Transportation of Ontario (MTO) transferred the responsibility of maintenance and upkeep along 14.2 km (8.8 mi) of Highway 17 east of "the split" with Ontario Highway 417 to Trim Road (Regional Road 57), a process commonly referred to as downloading.

. Despite the protests of the region that the road served a provincial purpose, a second round of transfers saw Highway 17 within Ottawa downloaded entirely on January 1, 1998. An additional 12.8 km (8 mi) was added to the length of Regional Road 174.
Highway 17 was also downloaded within the United Counties of Prescott and Russell, where it was redesignated as County Road 17.

Route description

Highway 17 crosses some of the most remote regions of Ontario. Although there are several settlements established throughout its length, the distance between gas stations can often exceed several hundred kilometres. Despite the isolation of the highway, it is well-travelled throughout its length. The section of Highway 17 north of Lake Superior is regarded as one of the most scenic drives in the province.
