Quebec Autoroute 5

Autoroute 5 (A-5, also known as the Autoroute de la Gatineau) is a short controlled-access Autoroute in the Outaouais region of western Quebec. It connects the central urban area of Gatineau (formerly Hull) with the recreational areas of Gatineau Park and the exurban rural areas of Chelsea and La Pêche. The southern terminus provides access to the Macdonald-Cartier Bridge, which continues into downtown Ottawa. The A-5 generally has four lanes of traffic (two per direction) with the exception of southernmost section across the Macdonald-Cartier Bridge where A-5 widens to six lanes (three per direction).

Part of Route 148 overlapped A-5 from Autoroute 50 to Boulevard Saint-Raymond until completion of Boulevard des Allumettières in 2007. With the completion of Boulevard des Allumettières, Route 148 was rerouted onto the southern leg of Autoroute 50 and then west towards Aylmer on Boulevard des Allumettières. Autoroute 5 is the only Quebec A-class Autoroute to have only 1 digit in its name.
