I park my car in St Stephen New Brunswick and walk across the bridge between St Stephen NB and Calais Maine. Please note that my car is a rental and I am not allowed to leave Canada with it. If the bridge is only for cars, is there another way to visit Calais Maine from St Stephen like a daily bus service. Please note we would like to return the same day if we visit Calais Maine from St Stephen. Any information given is greatly appreciated.
