OTTAWA – Beginning Monday, March 15, seasonal load restrictions will be in effect on Ottawa roads.

“Commercial vehicles or trailers with a gross vehicle weight in excess of five tonnes or 11,000 pounds per axle will be 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 lists,” city staff released in a statement today (March 3). “These restrictions also apply to all non-truck routes.”

During the spring thaw period, some roads cannot withstand heavy vehicle loads.

“Every year, the city monitors thaw progression by using the forecast temperature data to calculate the Thaw Index,” staff said. “When the Thaw Index reaches its threshold value, load restrictions are imposed. Heavy vehicles that exceed weight limits on restricted-load roadways during the spring thaw period will be subject to fines.”

Once the pavement strength has been restored, load restrictions will be removed.
