Premise: The Calais - Milltown Border Crossing connects the towns of Calais, Maine and St. Stephen, New Brunswick on the Canada–US border. This crossing is located at the Milltown International Bridge. Various bridges have existed at this location since 1825. Canada built its border crossing station in 1967. The US border station was built in 1938 and is planned to be replaced in 2014.
Hypothesis: This is not the Calais in France
