Décarie Interchange, Highway interchange in Montreal, Canada.

The Décarie Interchange connects Autoroute 15, Autoroute 20, and Route 136 through a multi-level turbine design in Montreal's road network system.

The interchange emerged during Montreal's infrastructure expansion in 1960, preparing the city's transportation network for the upcoming Expo 67 international exhibition.

The structure bears the name of the Décarie family, whose member Daniel-Jérémie served as mayor of Notre-Dame-de-Grâce from 1877 to 1904.

The interchange handles traffic between Montreal's north and south shores, facilitating movement through its multiple elevated ramps and connecting expressways.

Engineers constructed the interchange with specific height variations to manage traffic flow across different levels while maintaining noise reduction requirements.
