In 1936, the United States built a large border station that is still in use today, and is listed on the National Register of Historic Places.

By coincidence, the actual border crossing is on the Missisquoi River Bridge, built in 1929 and also listed on the US National Register.

The United States station is located at a bend in Vermont 105A, which bounds its parcel to the north and east.

It has a gambrel roof pierced by gabled dormers, and is flanked by single-story gable-roofed wings housing four garage bays each.

The main block is five bays wide, and is symmetrical, with a center entrance providing access to separate facilities for immigration and customs processing.
