Autoroute 73 (or A-73, also called Autoroute Robert-Cliche south of Quebec City, Autoroute Henri-IV from the Pierre-Laporte Bridge to the Autoroute Felix-Leclerc interchange and Autoroute Laurentienne to the north) is an important Autoroute in east-central Quebec, Canada. A-73 provides an important freeway connection to areas to the north and south of Quebec City, starting in the Beauce region and (currently) ending in the Laurentian Mountains north of Quebec City. Future extensions will take it farther north and south, into the Saguenay region and possibly to near the Maine border. Including concurrencies, A-73 is currently 116 km (72.1 mi) long.
