Seasonal load restrictions for heavy vehicles

REMINDER: During the spring thaw period, many roads in the City of Ottawa cannot withstand heavy loads.

As of 6 pm Thursday, March 15, 2012, all commercial vehicles or trailers with a gross vehicle weight in excess of 5 tonnes or 11,000 lbs. per axle are prohibited on roads where restriction signage is posted, and on all roads identified as restricted on the 2012 Truck Route Map.

These restrictions also apply to all non-truck routes. Heavy vehicles that exceed posted weight limits during the spring thaw period will be fined. For more information and to access the 2012 Truck Map, go to

Local restrictions will remain in effect on the identified City roads until further notice (typically, mid May).
