Quebec Route 136 (Montreal)

Route 136 (R-136), formerly Autoroute 720, known as the Ville-Marie Expressway (English) or Autoroute Ville-Marie (French) is an Autoroute highway in the Canadian province of Quebec that is a spur route of Autoroute 20 in Montreal. Its western terminus is located at the Turcot Interchange, a junction with Autoroute 15 and Autoroute 20, and its eastern terminus is near the Jacques Cartier Bridge (Route 134), where the highway merges with Notre-Dame Street. The Autoroute Ville-Marie designation is named after the downtown borough of Ville-Marie, through which the expressway is routed. It was designated Autoroute 720 until 2021 when it was renamed to Route 136.

Part of R-136 runs underground (below grade) through Downtown Montreal. This section begins from the west at Rue Guy (exit 4: Rue de la Montagne / Rue Atwater) and remains underground almost all the way to its eastern end, except for a short section between Rue Saint-Urbain and Rue Hôtel-de-Ville. The tunnelled section west of this gap is known as the Ville-Marie Tunnel, and the section east of it is known as Viger Tunnel. However, locals regard both tunnels as one, and the term Ville-Marie Tunnel is often used to refer to both tunnels.
