THUNDER BAY – During the spring thaw period, some roads cannot withstand heavy vehicle loads. Every year, the City monitors thaw progression by using forecast temperature data to calculate the Thaw Index. When the Thaw Index reaches its threshold value, the load restrictions are imposed. Once the pavement strength has been restored, the load restrictions are lifted.

Heavy load restrictions will come into effect for the City of Thunder Bay beginning at 8 am on Friday, March 15.

Commercial vehicles or trailers with a gross vehicle weight in excess of five tonnes or 11,000 pounds per axle are prohibited on all streets within the City of Thunder Bay limits with the exception of the streets or portions of streets listed below, which are exempt:
