Manitoba Provincial Road 577
Provincial Road 577 is a highway in the Parkland Region of Manitoba. It connects the communities of Rossman Lake, Marco, and Olha with Rossburn and Oakburn. While mostly an unpaved gravel road, it does contain two distinct paved sections, one between its western end and Rossman Lake, and the other between its southern end and Vista Road, as well as being paved within Olha. The highway does switch cardinal directions at the intersection with PR 566.
Route description
PR 577 begins in the Rossburn Municipality at an intersection with PR 264 north of the town of Rossburn. Heading east through farmland as a paved two-lane highway, it goes through a switchback before travelling along the south side of both Rossman Lake and the Sioux Valley Dakota Nation's Fishing Station 62A Reserve, where the pavement transitions to gravel. The highway travels through Marco, passing by the Marco Hall Monument and the Marconi School Historic Site before making a sharp turn to the south near the boundary of Riding Mountain National Park. After crossing Heron Creek twice, PR 577 has an intersection with PR 566, where the highway switches cardinal directions, before passing through the Olha community as it traverses a switchback. Heading south, the highway passes by both the Olha Lakes and Patterson Lake before passing just to the east of the Ukrainian Pioneer Mass Grave Historic Site. It has an intersection with Vista Road, where it becomes paved once again and enters the Rural Municipality of Yellowhead, ending at a junction between PTH 45 and PTH 21 on the northern edge of Oakburn.
History
Prior to 1992, all of PR 577 south of the junction with PR 566 was part of that highway, while PR 577 followed what is now PR 566 to an intersection with the former PR 359.
