Thousand Islands Bridge – Alexandria Bay / Lansdowne – US Interstate 81 / ON 137
The Thousand Islands “Bridge” is actually a series of bridges that cross the St. Lawrence River. In Canada, it connects with Highway 401, which runs northeast to Montreal and southwest to Toronto, and 416, which heads north to Ottawa.
Whichever bridge you take, you still need to go through customs as usual. This is one of the 10 most used border crossings between the US and Canada, and is the 4th busiest in New York. It therefore experiences significant backups during peak periods, and 2 hour delays are not uncommon during the summer. This is a heavy truck corridor, and I-81 is used by many carriers as an inland alternative to the more crowded I-95. In the past, delays have resulted in diversion of trucks to the Ogdensburg-Prescott Bridge.
Before heading to the border, be sure to review our pages on preparing for customs and prohibited items.
