Quebec Autoroute 50

Autoroute 50 (Autoroute Guy-Lafleur) is an Autoroute in western Quebec, Canada. It links Canada's National Capital Region (Gatineau) and the Greater Montreal area (Mirabel).

Until November 2012, there were two distinct sections of A-50: one section running eastward from Hull and the other westward from Mirabel. The gap in the highway was filled on November 26, 2012, and the two-lane freeway opened for traffic on the full 159 km (98.8 mi) length.

The route provides an east-west freeway alternative to Route 148 that does not require travelling in Ontario, unlike the main Trans-Canada Highway route (A-40 / Hwy 417).

Originally named Autoroute de l'Outaouais, it was announced on April 28, 2023, that A-50 would be renamed to Autoroute Guy-Lafleur in honor of the former Montreal Canadiens player who died of lung cancer a year earlier. The Quebec government officially announced the name change on May 4 in Thurso, Lafleur's birthplace.
