South of the Ville-Marie Expressway, the street crosses Old Montreal and is named rue Bonsecours. North of the Ville-Marie Expressway, it becomes Saint Denis Street and crosses the Quartier Latin. In the Quartier Latin, its vocation is primarily touristic and leisure-related, with restaurants and theatres located along this stretch. Near Saint Catherine Street, it crosses the downtown Université du Québec à Montréal campus while a little further north, it borders the Cégep du Vieux Montréal. North of Sherbrooke Street, Saint Denis Street enters the borough of Le Plateau Mont-Royal. In the Plateau-Mont-Royal and Rosemont-La Petite-Patrie to the north, it is a commercial street lined with small stores. Parallel streets are mostly residential. To the west, Saint Laurent Boulevard also serves a commercial purpose. In the boroughs of Villeray-Saint-Michel-Parc-Extension and Ahuntsic-Cartierville, Saint Denis Street is mainly residential. However, several businesses including green grocers and Vietnamese restaurants are located on the street. It is also one of the gateways to the Metropolitan Expressway. North of Crémazie Boulevard, it is a one-way northbound street with little traffic since the northbound Highway 335 continues along the Lajeunesse Street and Berri Street.
History
Saint Denis Street opened in the early nineteenth century on land acquired by Louis-Joseph Papineau and his aunt Perine Charles Cherrier, widow of Denis Viger. Extended several times, Saint Denis Street developed gradually after the construction of Saint Jacques Cathedral in 1836, facing Place Pasteur. Subsequently, it reached Sherbrooke Street near the end of the 19th century. During the mid-nineteenth century, this tree-lined residential street was inhabited by several representatives of the French Canadian elite. Before the end of the century, it began to transform into a commercial street, ascending slowly northward. In the early 20th century, the section of the Saint Denis Street between Dorchester Street and Sherbrooke Street became the centre of an francophone intellectual elite. Located in the area were the Université Laval à Montréal, the École Polytechnique de Montréal, the Saint-Sulpice Library and many bookstores. It was deserted by academics following the relocation of Université of Montreal and École Polytechnique on the northern slope of Mount Royal. From the late 1970s, the academic character of the neighbourhood returned with the construction of pavilions for the Université du Québec à Montréal, around the steeple of the old Saint Jacques Cathedral.
