PTH 45 provides an alternate route to Riding Mountain National Park for travelers coming from Saskatchewan and the western part of Manitoba as opposed to taking the Yellowhead Highway to Minnedosa and PTH 10 north.

Although PTH 45 is officially named the Russell Subdivision Trail, it is also dubbed derisively as "The Turkey Trail" by some locals, particularly ones who live along or near the eastern section of the highway. The latter moniker is because the highway has a narrow and winding nature in that portion, resembling the winding bush paths commonly found on Prairie farms.

The speed limit is 100 km/h (62.5 mph).
