Route description

PR 458 begins along the border between the Municipality of Killarney-Tuttle Mountain and the Cartwright-Roblin Municipality at a junction with PTH 3 (Boundary Commission Trail), with the road continuing south as Road 90W. It heads north along the border to travel through the east side of Holmfield, where it crosses a bridge over the Long River, before going through a switchback to fully enter the Cartwright-Roblin Municipality. After joining a short concurrency with eastbound PR 253, where the cross the Pembina River into the Rural Municipality of Prairie Lakes, the highway heads through a switchback as it passes by the hamlet of Pleasant Valley before heading north through rural farmland for several kilometres, coming to an end just south of Belmont at an intersection with PTH 23, with the road continuing north into town as George Street. With the exclusion of the concurrency with PR 253, which is paved, the entire length of PR 458 is a gravel two-lane highway.^[1][2]
