Seaway Bridge – Massena, Rooseveltown / Cornwall – New York Highway 37 / Ontario Highway 138
This bridge was re-named the Three Nations Bridge Crossing in recognition of all 3 Nations it connects: Canada, Akwasasne, and the U.S.A. The “bridge” actually consists of two separate bridges – one that spans the St. Lawrence Seaway and the other connects the 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.
In January 2014, the Seaway International Bridge opened a new “low-level” bridge linking Cornwall to Cornwall Island and the CBSA moved to a new location in Cornwall shown in the picture above. This greatly improved entry to Canada and wait times are way down from the delays before the span was installed. The eventual plan is to move both the U.S. and Canadian ports to Massena but it could take many years to resolve this issue and construct a permanent port.
