Route 133 is a historic and heritage road of the Montérégie region in the province of Quebec, with north/south orientation and located on the eastern shore of the Richelieu River. Its northern terminus is in Sorel-Tracy, on the south shore of the Saint Lawrence River. The southern terminus is in Saint-Armand at the United States border with Vermont, close to Highgate Springs, where it continues southward past the Highgate Springs-St. Armand/Philipsburg Border Crossing as Interstate 89. Prior to the 1970s, the portion between the international border and Saint-Jean-sur-Richelieu was known as Route 7, which served as a continuation of US 7.

Route 133 is designated as historic and called Chemin des Patriotes in honour of the Patriot Rebellion of 1837-1838.

The stretch between the US border and Saint-Jean-sur-Richelieu, where Autoroute 35 begins, is relatively busy, as it provides the main link between Boston and Montreal. Construction to extend Autoroute 35 South of Saint-Jean-sur-Richelieu to the US border by-passing Route 133 started in 2009. Construction is slated to be finished in 2017.
