Along with U.S. 83, PTH 83 is part of a continuously numbered north–south highway in North America with a combined distance of 3,450 kilometres (2,140 mi).

[3][4] A small portion of PTH 83 between Roblin and Russell was reconstructed due to a large slide that occurred in early July 2012.

The area affected was located one kilometre north of PR 366 at the bottom of the Shell Valley with traffic detoured around that portion of highway.

PR 486 begins at an intersection with PTH 83 just north of Durban, heading south as a paved, two-lane highway to cross a railway and travel along the eastern side of town.

Shortly after leaving Durban, the highway makes a sharp left and transitions to gravel, winding its way northeast through rural farmland to cross Ruby Creek several times before having a junction with PR 488 just west of Pretty Valley.

Now regaining asphalt, the highway heads due north to travel just east of Kenville to cross the Roaring River twice and have an intersection with PR 485.

Shortly thereafter, PR 486 crosses a railway before coming to an end just south of Swan River at another intersection with PTH 83.
