The Seaway Bridge was re-named the Three Nations Bridge Crossing in recognition of all 3 Nations it connects: Canada, Akwesasne, and the U.S.A. The “bridge” actually consists of two separate bridges – one that spans the St. Lawrence Seaway from Massena and another that connects the Canadian city of Cornwall to Akwesasne (on Cornwall Island). The Seaway crossing carries more passenger vehicles than any other crossing in Northern New York, although most of the traffic is local.
Before heading to the border, be sure to review our pages on preparing for customs and prohibited items.
