The Olivier Charbonneau Bridge is a toll bridge over the Rivière des Prairies, between Laval's Duvernay district and Montreal's Rivière-des-Prairies–Pointe-aux-Trembles borough. The long anticipated construction began in early 2008, despite a last-ditch attempt by Greenpeace to block the project, and the bridge was opened to traffic on May 21, 2011, at 12:30pm (EDT).
