International Avenue Bridge

The International Avenue Bridge is an international bridge across the St. Croix River, connecting the town of St. Stephen, New Brunswick in Canada with the city of Calais, Maine in the United States.

It is the third, busiest, and newest bridge connecting the two communities, in addition to the Ferry Point International Bridge and the Milltown International Bridge. The International Avenue Bridge serves commercial, cargo, trucking, passenger vehicles, campers, RVs, buses and other heavy and through traffic, while both the Ferry Point and Milltown crossings remain in use for passenger vehicles and local traffic, which could also use the International Avenue Bridge.
