PR 351 was part of the original
Highway 1 prior to 1958. In 1962, Highway 1 became part of the
Trans-Canada Highway. The current configuration of Highway 1 began construction in 1957 and was opened to traffic the following year, putting the new route north of Carberry. The route was given its current designation when the Manitoba government implemented its secondary highway system in 1966. ==Major intersections==
