History
In the early 1990s, the Manitoba government decommissioned a number of provincial secondary roads and returned the maintenance of these roads back to the rural municipalities. A portion of the original PR 354 was included in this decommissioning. However, unlike most provincial roads in which the length was shortened or the route decommissioned altogether, PR 354 was slightly lengthened from its original distance. Prior to this, PR 354's northern terminus was at Horod with PR 359. The road extended another past its current southern terminus to meet eastbound PR 259. The two roads continued in a western concurrence for before turning south, traveling through Bradwardine before PR 259 turned west and left the concurrence. PR 354 continued south for to its southbound terminus with PTH 21 near the Sioux Valley Dakota Nation. After the decommissioning of the original section, PR 354 was rerouted east onto the former PR 359, which was significantly shortened from its original length. The road traveled on this section to meet PR 270. PR 270 was initially extended on to the section between PR 354's current northern terminus and the current junction between the two roads; it was changed to PR 354 in 1997. This section includes the former PR 263, which was decommissioned in its entirety. The section between PR 259 and its old southbound terminus was redesignated as PR 564. The section between PR 259 and PR 354's current southern terminus is now a municipal road. The original length of PR 354 was.
