Autoroute 31 (A-31) is an Autoroute in the region of Lanaudière in Quebec. Constructed in 1966, A-31 primarily links Joliette with A-40 and in turn to Montreal, Trois-Rivières, and other points served by Quebec's autoroute system. A-31 is only 14 km (8.7 mi) long, making it one of the shortest autoroutes in the province. It is multiplexed with Route 131 for its entire length.
A-31 carries the name Autoroute Antonio-Barrette, named for a politician from Joliette who briefly served as Premier of Quebec in 1960.
