Autoroutes Bonaventure and des Cantons-de-l'Est (A-10)

Bonaventure Expressway begins in Downtown Montreal and runs beside Montreal Technopark. Then, on Nun's Island, it connects to Champlain Bridge and becomes Eastern-Townships Autoroute. On South Shore, its route is sinuous. It follows townships bordering, circumverting Montérégiennes Mountains. A-10 leans on A-55 (old A-51) corridor on a short distance, then detaches and ends east of Sherbrooke as a Super-2.
 
Formerly under Québec's Autoroutes Office, this expressway was tolled on all its lenght.
