It runs from the US Border near Port of Oungre (where it meets United States Route 85) to a dead end near the north shore of Tobin Lake. Saskatchewan Highway 35 (SK Hwy 35) is about long. The CanAm Highway comprises Saskatchewan Highways 35, SK Hwy 39, SK Hwy 6, SK Hwy 3, SK Hwy 2 and U.S. Route 85. of SK Hwy 35 contribute to the CanAm Highway between Port of Oungre on the Canada – United States border and Weyburn. Mudslides, and spring flooding were huge road building and maintenance problems around Nipawin as well as along the southern portion of the route named the Greater Yellow Grass Marsh. Over 20 early dams were built until the problem was addressed with the Rafferty-Alameda Project on the Souris River and the construction of the Qu'Appelle River Dam which have helped to eliminate washed out roads and flooded communities. The highway through the homesteading community followed the Dominion Land Survey on the square until reaching the Saskatchewan River at Nipawin. The E.B. Campbell Dam built in 1963 created both Tobin Lake and Codette Lake followed by the bridge construction in 1974 which retired the ferry and basket crossing for traffic north of Nipawin and north of Tobin Lake.
