The Thousand Islands Bridge is not a single bridge but rather a series of five bridges that span the St. Lawrence River. The southern end of the bridge connects with U.S. Interstate 81 while the northern end of the bridge connects to Canadian Highway 401 via Highway 137. There is also an interchange with the Thousand Islands Parkway on the Ontario side.
