Provincial Road 342 (PR 342) is a 57.2adj=midNaNadj=mid north–south highway in the Pembina Valley and Westman regions of Manitoba, Canada. Mostly a two-lane gravel road, it connects Clearwater with Glenora, Greenway, and Cypress River.
PR 342 begins in the Municipality of Louise at the southern edge of Clearwater at a junction with PTH 3A. It winds its way through carved by Cypress Creek, passing under a railroad overpass and crossing the creek before entering downtown along Boundary Trail. In the centre of town, the highway makes a sharp right onto 11th Street N, following it northward through neighbourhoods before leaving Clearwater as it crosses another bridge over Cypress Creek, where the pavement transitions into gravel. PR 342 goes through several switchbacks as it winds its way northwest, lowering itself down into the Pembina River Valley to have an intersection with PR 442 and cross a bridge over the Pembina River. Entering the Rural Municipality of Argyle, it rises back out of the valley to run concurrently with PR 253, with the two heading due west along the northern side of Rock Lake before making a sharp right turn at a junction with an access road to the lake. Just east of Glenora, PR 342 splits off and heads east, then north through rural farmland for several kilometres, where it passes along the eastern edge of Greenway and has an intersection with PTH 23. Continuing north through rural areas, it has an intersection with PR 245 before going through a switchback to begin following the boundary line between the Municipality of Glenboro-South Cypress and the Rural Municipality of Victoria. Entering the town of Cypress River after crossing a former railway, the highway becomes paved as it travels along the western edge of downtown before coming to an end at a junction with PTH 2 (Red Coat Trail).[1]
