About

The Thousand Islands Bridge serves as a vital international connection between the United States and Canada, linking Interstate 81 in New York to Route 401 in Ontario. Opened in 1938, this engineering marvel spans the picturesque Thousand Islands region, a popular and scenic area straddling the border between the two nations. The bridge’s strategic importance is underscored by its location in the municipality of Orleans, within Jefferson County, New York.

Nestled at the centroid coordinates of 44°18’08″N 75°58’58″W, the Thousand Islands Bridge consists of five spans that elegantly traverse the waterways and islands of this unique region. It stands not only as a crucial infrastructure component facilitating cross-border travel but also as an iconic symbol of connectivity amidst the natural beauty of the Thousand Islands. The bridge’s significance is enhanced by its role in linking two major highways, thereby playing a key part in the transportation network of this binational area.
