Autoroute 55 (also called Autoroute de l'Énergie north of the Autoroute 20 and Autoroute Joseph-Armand Bombardier south of it) is an important north-south Autoroute and the only one running in that direction in central Quebec. It is the longest north-south Autoroute, beginning as the continuation of I-91 at the Canada–United States border near Stanstead and continuing to Shawinigan, where it downgrades to Route 155. The total length of A-55 is currently 247 km (153.5 mi) long, including concurrencies with Autoroute 10, Autoroute 20 and Autoroute 40.
Autoroute 55 connects the mid-sized communities of Sherbrooke, Drummondville, Trois-Rivières and Shawinigan and the smaller communities in between. The most notable feature on A-55 is the Laviolette Bridge between Trois-Rivières and Bécancour, which is one of the longest bridges in Quebec and in Canada.
