Location

The bridge is among the busiest on the Canada–United States border in the state of New York, with about two million crossings a year.[1] It is jointly owned by the Federal Bridge Corporation (a Crown corporation of the Canadian federal government) and the Saint Lawrence Seaway Development Corporation (an agency of the United States Department of Transportation), and is operated by the Seaway International Bridge Corporation, which came under the control of the Federal Bridge Corporation from the Saint Lawrence Seaway Authority in 1998.

Previously known as the Cornwall-Massena International Bridge, the SIBC was a private bridge whose outstanding stock was purchased by the Saint Lawrence Seaway Authority (Canada) and the Saint Lawrence Seaway Development Corporation (U.S.) in 1957. It was incorporated in Canada five years later.

In 2000, the international border crossing that the Seaway International Bridge comprises was named the Three Nations Crossing, in recognition that it connects the Akwesasne Mohawk Territory, a self-governing nation, to the United States and Canada.

On January 24, 2014, the opening of a new lower-level bridge marked the official closing of the former high-level North Channel crossing of the Seaway International Bridge. This project was estimated to cost $75 million, entirely funded by the Government of Canada. It was announced in 2010 that the Government of Canada would be going forward with this project that would involve the construction of a new low-level bridge as well as the demolition of the Seaway International Bridge to ensure the longevity of the border crossing, assuring that the former bridge was still in safe driving condition. The high-level Seaway International Bridge was completely demolished in 2015.[2] At the opening ceremony of the new bridge, the first person to make the crossing was Raymonde Champagne, who had also been the first person to cross the high-level bridge in 1962.[3]
