Seasonal load restrictions to go into effect for heavy vehicles

February 26, 2018
Announcements and Events

Beginning at 12:01 a.m. on Monday, March 5, seasonal load restrictions are in effect. Commercial vehicles or trailers with a gross vehicle weight in excess of five tonnes or 11,000 pounds per axle are prohibited on roads where restriction signage is posted, and on all truck routes identified as restricted on the Urban Truck Routes and Rural Truck Routes.

These restrictions also apply to all non-truck routes. Heavy vehicles that exceed weight limits on restricted load roadways during the spring thaw period will be subject to fines.

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.
