Provincial Road 322 (PR 322) is a 41.6adj=midNaNadj=mid north–south highway in both the Interlake and Winnipeg Metro regions of Manitoba, Canada. It connects the communities of Grosse Isle, Argyle, Woodroyd, and Erinview.
PR 322 begins in the Rural Municipality of Rosser in the town of Grosse Isle at an intersection with PTH 6 (Northern Woods and Water Route. It heads north through town along Road 1E, crossing both the Prairie Dog Central Railway and PR 321, where it enters the Rural Municipality of Rockwood, before leaving Grosse Isle and continuing north through rural farmland for the several kilometres. After passing by the Manitoba Hydro training facility, the highway has a junction with PTH 67 before continuing on through more rural areas to enter Argyle and join a concurrency (overlap) with PR 323. The pair head due west through the centre of town before becoming unpaved as the road leaves Argyle and enters the Woodlands. PR 322 splits off and heads north shortly thereafter, trading farmland for forests to pass through Woodroyd, where it has an intersection with Road 85N (former PR 517), traverse some switchbacks to travel along eastern coastline of the Shoal Lakes, where it comes to an end just west of Erinview at an intersection with PR 415.[1]
