Autoroute 25 (or A-25, also called Autoroute Louis-H.-La Fontaine in Montreal) is an Autoroute in the Lanaudière region of Quebec. It is currently 49 km (30.4 mi) long and services the direct north of Montreal's Metropolitan Area. A-25 has one toll bridge, which is the first modern toll in the Montreal area and one of two overall in Quebec (after being joined by the A-30 toll bridge, which opened in 2012).
A-25 begins at an interchange with A-20 and Route 132 in Longueuil and quickly enters the Louis Hippolyte Lafontaine Bridge-Tunnel into the east end of Montreal. It is the main north-south freeway in the east end of Montreal (actually northwest-southeast but perpendicular to the St. Lawrence River).
Before the Montreal-Laval Extension, a gap existed in A-25 north of the interchange with Autoroute 40. Instead it followed Boulevard Henri-Bourassa to Boulevard Pie-IX, both of which are principal urban arterial roads. Boulevard Pie-IX north of Boulevard Henri-Bourassa was used as a temporary section of Autoroute 25 across the Rivière-des-Prairies to Autoroute 440. From there, A-25 proceeded east with A-440, then continued north and east of Laval.
The designation of Autoroute Louis-Hippolyte-Lafontaine is named after Louis Hippolyte Lafontaine, a 19th-century Lower Canada leader of what was then the Province of Canada.
A-25 is also part of the Trans-Canada Highway between the A-20 and A-40 interchanges.
