From Ottawa, the Trans-Canada Highway continues as a freeway and proceeds east to Montreal, as Highway 417 in Ontario (and the Queensway in Ottawa) and in Quebec. The Trans-Canada assumes the name (also known as "The Met" or "Metropolitan Boulevard") as it traverses Montreal as an elevated freeway. At the Laurentian interchange, in Montreal, the Abitibi route (Highway 66, Route 117, A-15) rejoins the main TCH line. The TCH then follows Autoroute 25 southbound, crossing the St. Lawrence River through the Louis-Hippolyte Lafontaine Bridge–Tunnel, and proceeds northeast on Autoroute 20 for to (across from Quebec City).
