The Vanceboro–St. Croix Border Crossing connects the towns of Vanceboro, Maine and Saint Croix, New Brunswick on the Canada–United States border. The Canadian government has at times called this crossing McAdam, named for the larger municipality east of St. Croix. In the early 1900s, this crossing was located at the adjacent lock structure a short distance to the north. At some point in the distant past (at least prior to 1930), a bridge existed to the south of the railroad bridge, extending from Public Crossing Road on the Canadian side. Concrete footings for this bridge remain on the US side at this site.
A few hundred yards south of this crossing is also an international rail bridge which is notable for the 1915 Vanceboro international bridge bombing incident where a German spy attempted to destroy the bridge. Prior to the 1956 completion of Interstate 95, this border crossing was part of the primary route between Bangor, Maine and Fredericton, New Brunswick.
This Border Crossing isn’t 24 Hours anymore due to train traffic.
