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.
