Ontario Highway 141 History - The King's Highways of Ontario

King's Highway 141 is a minor collector highway in the District of Parry Sound and the District Municipality of Muskoka which serves the northern Muskoka Lakes region. Highway 141 connects Highway 11 near Utterson with Highway 400 south of Parry Sound. The highway was created in 1974 when Secondary Highway 532 was renumbered as King's Highway 141 between Utterson and the Highway 69 Junction at Hayes Corners. The new route number came into effect on December 18, 1974. The highway was approximately 50 km in length. The route of Highway 141 remained more or less unchanged until 2003, when Highway 141 was extended westerly from the Highway 69 Junction at Hayes Corners to the new Highway 400 Extension. The new Highway 400 opened to traffic between MacTier and Horseshoe Lake on October 7, 2003. The project included a new interchange at Highway 400 & Highway 141. The extension from Hayes Corners to Highway 400 added approximately 4 km to the length of the highway.

Highway 141 is a two-lane highway for its entire length. The highway passes through predominantly rural areas along its route. Services are rather scarce along this highway outside of larger communities. The speed limit on Highway 141 is 80 km/h (50 mph), unless posted otherwise.
