Highway 4 is a major highway in the Canadian province of Saskatchewan. It runs from U.S. Route 191 at the United States border near Monchy to Highway 224 / Highway 904 in Meadow Lake Provincial Park. Highway 4 is about long.
Major communities that Highway 4 passes through are Swift Current, Rosetown, Biggar, Battleford, North Battleford, and Meadow Lake. It also passes The Battlefords Provincial Park.
Highway 4 was originally designated as Provincial Highway 1, while the present-day Highway 1 was designated as Provincial Highway 4.[1] The designations were switched around to allow for the future Trans-Canada Highway to have the same number across western Canada.[2]
Several maps, such as MapArt's mapbook of Saskatchewan Cities and Towns shows a Highway 4S spur heading east from the intersection of Highway 4 in Swift Current to the city's airport, following Airport Road.[3] The roadway is not designated Highway 4S on the Saskatchewan Highway's Official Highway Map.[4] [5]
