Bridge Access for International Travel Via Canada

Access St. Lawrence County from Canada via one of two major crossings.

Three Nations Bridge / Seaway International Bridge

Entering from Cornwall Canada via Massena

The Seaway International Bridge in Massena is a popular access point for St. Lawrence County visitors, including access by automobiles, cyclists and pedestrians. The Seaway International Bridge links Cornwall, Ontario, Akwesasne, and Messena and was renamed the Three Nations Bridge Crossing in recognition of the 3 nations it connects, including Canada, Akwasasne, and the U.S.A. Vehicle toll costs can be paid in either Canadian or US dollars and usually between $3.00 and $4.00, though pedestrians and cyclists can enjoy free entry.

For information on current wait times, toll rates, commuter cards and frequent users discounts, or for more specific information about this bridge crossing, we suggest contacting the Seaway International Bridge Corporation directly.

Ogdensburg-Prescott International Bridge

Entering from Canada via Ogdensburg

The Ogdensburg–Prescott International Bridge is a popular and convenient entry point for Canadian or travelling visitors to St. Lawrence County. The bridge itself connects Ogdensburg, New York in the United States to Johnstown, Ontario in Canada.

Though access is limited to vehicles only with no foot traffic, more often than not, wait times at this entry point are nearly non-existent making it a quick trip over the 1.5-mile bridge. The toll cost is generally around $3.25 USD when entering from Canada.

For information on current wait times, toll rates, commuter cards and frequent users discounts, or for more specific information about this bridge crossing, we suggest contacting the Ogdensburg Bridge & Port Authority directly.
