The Laviolette Bridge (French: pont Laviolette) is an arch bridge connecting the city of Trois-Rivières, Quebec, Canada to Bécancour on the south shore of the Saint Lawrence River via Autoroute 55.

The bridge, an impressive structure with elegant aesthetics, has become a major landmark of Trois-Rivières and the Mauricie region.

On September 8, 1965, an explosion led to the bursting of a caisson because of water pressure, causing the death of twelve workers.

The bridge was inaugurated on December 20, 1967 by Fernand Lafontaine, the ministre de la voirie (minister of highways) of the government of Daniel Johnson, Sr.

In 2005, the Ministry of Transport of Québec began a three-year major renovation project, which caused major traffic jams throughout the summer of 2005, when the middle of the bridge was repaired.
