The '''Pierre Laporte Bridge''' ({{langx|fr|Pont Pierre-Laporte}}{{efn|{{IPA|fr|pɔ̃ pjɛʁ lapɔʁt|pron}}}}) is the longest main span suspension bridge in Canada.<ref>Although Île d'Orléans Bridge is over 4 km in total length, its longest suspended span is 323 m and its total suspended length is 677 m, less than Pierre Laporte's 1,041 meters full length.</ref> It crosses the Saint Lawrence River approximately {{convert|200|m|ft}} west (upstream) of the Quebec Bridge between Quebec City and Lévis. It spans {{convert|1041|m}}.<ref name="ea" />
It was originally named the '''New Quebec Bridge''' (''Nouveau pont de Québec'') and was supposed to be called Pont Frontenac (Frontenac Bridge) until it was renamed in honour of Quebec Vice-Premier Pierre Laporte, who was kidnapped and murdered during the October Crisis of 1970 as construction of the bridge was nearing completion. The bridge was constructed for the Province of Quebec, Department of Roads in a joint venture with the private firm of Parsons Transportation Group.
It carries Autoroute 73 northbound from Autoroute 20, the Trans-Canada Highway, to Quebec City and Autoroute 40 and also northwards towards Saguenay.
