Tolls and currency exchange rates
Since September 1, 2000, the Sault Ste. Marie International Bridge has been jointly operated under an agreement between the St. Mary's River Bridge Company (the Canadian owner), and the Michigan Department of Transportation (the Michigan owner).

Under the agreement, the toll rate in Canadian currency is adjusted twice a year to keep its value within a nickel of the U.S. currency toll rate. 

  • On October 1st, the Canadian currency toll rate is adjusted based on the average daily currency exchange rate for the previous six-month period ending September 1. 
  • On April 1st, the toll is adjusted based on the average daily exchange rate for the six-month period ending March 1st.

For more information, see these recent press releases about the rate changes.
