Saskatchewan Highway 11

Highway 11 is a major north–south highway in Saskatchewan, Canada, that connects the province's three largest cities: Regina, Saskatoon, and Prince Albert. It is a structural pavement major arterial highway which is approximately 393 kilometres (244 mi) long. It is also known as the Louis Riel Trail (LRT) after the 19th century Métis leader, Louis Riel. It runs from Highway 1 (the Trans-Canada Highway) in Regina north until Highway 2 south of Prince Albert. Historically the southern portion between Regina and Saskatoon was Provincial Highway 11, and followed the Dominion Survey lines on the square, and the northern portion between Saskatoon and Prince Albert was Provincial Highway 12.

From Regina to Saskatoon, Highway 11 is a four-lane divided highway except in the village of Chamberlain, where the road narrows to two lanes through the community, including its intersection with Highway 2 south to Moose Jaw. Highway 11 passes through Saskatoon, officially following Idylwyld Drive through the downtown area; however, Circle Drive is also signed as Highway 11 which serves as bypass route. North of Saskatoon, the road continues as a four-lane divided highway past the communities of Warman, Osler, Hague, Rosthern, and Duck Lake. Highway 11 then runs through the Nisbet Provincial Forest and past the hamlet of MacDowall before it reaches its northern terminus with Highway 2 approximately 7 kilometres (4 mi) south of Prince Albert.

Most of the intersections along the highway are at-grade; however, there are several interchanges and overpasses along the Regina Bypass and through Saskatoon. There is a partial cloverleaf at Lumsden in the Qu'Appelle Valley and another one at Warman.
