Calais / International Avenue Border Crossing

Calais / Saint Stephen – International Avenue, Route 1, Maine Route 9  / New Brunswick Route 1

Looking towards the U.S. at the U.S. Customs office.

This new bridge was opened in 2010 to relieve the heavy traffic and extensive delays that existed at the nearby border crossings at Milltown and Ferry Point.  These crossings combined to form the 8th busiest commercial crossing along the U.S and Canadian border with delays of up to 2 hours.

In Maine, the bridge connects to Maine State Route 9, which in turn links to Interstate 95 in Bangor.   On the New Brunswick side, the bridge connects to a four-lane segment of New Brunswick Route 1.   All commercial traffic is required to use this new crossing and any commercial vehicle that arrives at either the Ferry Point or Milltown will be turned around.  The older border crossings remain open for passenger vehicles.  The Canadian CBSA calls this port the “St. Stephen 3rd Bridge” while U.S. Customs calls it the “International Avenue” crossing.
