This highway is the main access road to the renowned Souris Swinging Bridge.

[1][2] PTH 22 begins roughly 1 kilometre (0.6 mi) east of Elgin in the Rural Municipality of Grassland at a junction with PTH 23, with the road continuing south a short distance to Whitewater Recreation Park.

[7] The route kept this designation until 1959, when PTH 12 was extended north, replacing Highway 22.

Signed as a north-south highway, it runs mostly east-west, entirely as a gravel two-lane road, providing access to rural areas within the RM as well as a crossing of the Souris River.

Now mostly municipally maintained, some sections still belong to the province, including its current alignment and what is now PR 541.
