You may have noticed when crossing to the states -- you only have two options. Not three.
The Milltown Port of Entry to the U.S. in St. Stephen is now temporarily closed until Fall. Customs and Border Protection says one lane on the bridge is barricaded to allow for the demolition and reconstruction of a new port entry at that location.
Throughout the summer, the Ferry Point Bridge in downtown St. Stephen will remain open to passenger vehicles only, and the International Avenue "Third Bridge" is open to both passenger vehicles and commercial trucks.
CBP says the barricades will be up until September or October of 2013, and you can still cross back to Canada using the Milltown bridge.
