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.

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.
