Since September 1, 2009, the Sault Ste. Marie International Bridge has been jointly operated by virtue of a cooperative intergovernmental agreement between the St. Mary’s River Bridge Company (owner of the half of the bridge in Canada, and the Michigan Department of Transportation (owner of the half of the bridge in the United States).
A provision in the agreement requires that toll equity in terms of currency exchange rates be maintained to within a nickel of the U.S. currency benchmark. The adjustment shall be made to the nearest nickel, rounded as may be necessary for administrative efficiency.
The agreement requires that on October 1 and April 1 of each year the Canadian currency toll rate be adjusted based on the average daily currency exchange rate for the previous six-month period ended September 1 and March 1 respectively.
Toll payments must be made in full in either U.S. or Canadian Funds. Mixed currency payments will not be accepted.
