History
In 1961, the province of Manitoba declared the section of modern-day Highway 39 from Simonhouse to Wekusko Lake as a gravel road and a section of modern-day Highway 6 from the lake to Opswagon Lake paralleling the Grand Trunk Railway as a flat-earth road, while there a finished stretch in the area of Thompson as a gravel road, with a spur to Mystery Lake. By 1966, the sections had been designated as Provincial Road 391 from Simonhouse to Thompson, while the spur to Mystery Lake and the Thompson Airport was designated as PR 382. By 1969, the section of modern-day PR 391 from Lynn Lake to the shores of the Churchill River near Leaf Rapids was constructed as an all-weather road. The next year, the route had been extended to the Suwanee River and designated as part of PR 391. The section between the Suwanee River and Thompson was also proposed as a new all-weather road while PR 382 between Thompson and the airport was decommissioned and absorbed into PR 391. PR 391 was completed the next year from the airport westward to an area several kilometres northwest. By 1973, PR 391 was extended westward to a creek from Footprint Lake with a span to Nelson House. Finally, the road was completed between the Suwanee River and the creek, marking the completion between Lynn Lake and Thompson. In 1987, PR 391 was truncated back all the way to Thompson and replaced with Highway 39 from Simonhouse to Wekusko Lake and Highway 6 between Wekusko Lake and the southern border of Thompson.
