Route description

Highway 31 as it passes through the gorge created by the Pembina River

PTH 31 begins at the North Dakota border in Windygates, with the road continuing south into Maida and toward Langdon as North Dakota Highway 1 (ND 1). The highway curves northward, leaving Windygates and traveling through rural farmland for a few kilometers, where it crosses PR 201, providing access to nearby Pembina Valley Provincial Park. It now winds its way down, then back up, the Pembina River valley, where it crosses a bridge over the Pembina River. PTH 31 heads north through farmland for a few more kilometers before coming to an end at an intersection with PTH 3 (Boundary Commission Trail) just southeast of Darilngford. The road continues north as PR 240.^[1][2]

The entire length of Manitoba Highway 31 is a rural, paved, two-lane highway.

History

Highway 31 was the designation of the route connecting PTH 16 (then known as Highway 4) at Russell to PTH 5 in Roblin. In 1947, it extended north via Benito to Highway 10 at Swan River, replacing Highway 6. The section from Roblin to south of Benito was under construction; it opened in 1948.^[3] In 1954, the section of PTH 83 between the Trans-Canada Highway and Birtle was constructed and opened to traffic. With this addition, PTH 83 was also extended to Swan River, replacing Highway 31.

PTH 31 was designated to its current route in 1959.^[4]
