There are two toll bridges in Quebec: one along autoroute A-25 and another on A-30. The highway bridge A-25 is also known as "Olivier Charbonneau Bridge" while the one on A-30 is famous as "St. Lawrence bridge".

A25 Bridge or Olivier Charbonneau Bridge

The A25 Bridge[1], also known as “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 bridge uses an electronic toll system that allows vehicles to cross the bridge without having to stop at a traditional toll booth. Users can activate an A25 client account and install an A25 transponder on their vehicle’s windshield. Crossing the bridge without a transponder triggers the system to automatically take a picture of the vehicle’s license plate and send an invoice by mail. Users must settle the bridge-crossing toll and the applicable administration fees in the prescribed time, otherwise additional collection charges may be added to the toll.

The fee schedule varies on the vehicle’s size (over or under 230 cm in length), the crossing time of day and the traffic when over a certain threshold. Pedestrians, cyclists and, electric vehicles can cross the bridge for free.

A30 Bridge or St. Lawrence Bridge

The A30 Express Bridge[2], also known as “St. Lawrence bridge”, is a toll bridge over the St. Lawrence river. The toll bridge is a section of Highway 30 between Châteauguay and Vaudreuil-Doriona.

Tolls on this toll bridge can be paid with the A30 Express Transponder. All electric vehicles equipped with an A30 Express transponder are not subjected to toll fees.
