Milltown International Bridge, International road bridge in St. Stephen, Canada and Calais, United States.
The Milltown International Bridge is a road bridge spanning the St. Croix River between New Brunswick, Canada, and Maine, United States. It carries only non-commercial passenger vehicles across the border, with dedicated customs facilities on each side to process travelers.
The bridge opened in 2009 and was the first new border crossing between Canada and the United States built in over 40 years. It was constructed to meet growing demand for cross-border connections between the two nations.
The bridge links two neighboring communities with long-standing ties and daily interactions. Residents on both sides use it routinely for visiting, shopping, and family gatherings.
The bridge is open year-round with customs facilities on both sides ready to process travelers. Keep your travel documents accessible and expect to stop briefly for border inspection before continuing.
The bridge sits between two other international crossings and exclusively serves private vehicles, setting it apart from the nearby routes. This restriction makes it a quieter passage for personal travel between the neighboring communities.
