Provincial Road 405 (PR 405) is a 15.5adj=midNaNadj=mid east–west highway in both the Eastman and Winnipeg Metropolitan Regions of Manitoba, connecting the towns of Île-des-Chênes and Lorette. The majority of the highway is paved.
PR 405 begins in the Rural Municipality of Ritchot at a junction with PTH 59 on the north side of Île-des-Chênes, heading due east as a paved two-lane highway to have an intersection with Main Street before leaving town heading through rural farmland for a few kilometres to enter the Rural Municipality of Taché. It makes both a sharp left then a sharp right as it begins following both the south bank of the Seine River and the southern edge of Lorette, where it has an intersection with St. Amant Avenue. With the asphalt turning to gravel shortly thereafter, PR 405 leaves Lorette behind and continues east, paralleling the river for several more kilometres before coming to an end at a junction with PR 206. Portions of the highway go by the street names Van Gorp Road, Brule Road, Manning Road, and River Road.[1]
