Autoroute 50 (Autoroute de l'Outaouais) 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.
