Saskatchewan Highway 35

Highway 35 is a paved, undivided provincial highway in the Canadian province of Saskatchewan. It runs from the U.S. border at the Port of Oungre (where it meets U.S. Route 85) north to a dead end near the north shore of Tobin Lake. The southern end of Highway 35 is one segment of the CanAm Highway, which is an international highway connecting Canada, the United States, and Mexico. Highway 35 is about 569 kilometres (354 mi) long.

Highway 35 connects with the following major Saskatchewan highways: 18, 39, 33, 48, 1, 22, 15, 16, 5, 3, and 55. Major communities along the highway include Weyburn, Qu'Appelle, Fort Qu'Appelle, Wadena, Tisdale, and Nipawin. Parks accessed from the highway include Oungre Memorial Regional Park, Mission Ridge Winter Park, Nipawin & District Regional Park, and Tobin Lake Recreation Site (Caroll's Cove Campground).

Mudslides and spring flooding were huge road-building and maintenance problems on various stretches of Highway 35, including along the southern portion through the Greater Yellow Grass Marsh and along the Souris River, in the middle section through the Qu'Appelle Valley, and in the northern section by Nipawin and at the Saskatchewan River. Several dams and water control measures were built over the years to control flooding.

The 2018 Humboldt Broncos bus crash occurred on Highway 35 at the intersection with Highway 335 about 28 kilometres (17 mi) north of Tisdale.
