Reduced Load Restriction
To reduce the effects heavy vehicles have on roadways during the spring thaw, there is a period of reduced loading on certain roads. During this time, the maximum weight must not exceed five tonnes per axle.
The reduced load period runs from approximately mid-March to early June but may vary depending on the road conditions. All roads covered by half loading are posted with regulatory signs.
