Conditions to be met when constructing, improving or repairing wooden culverts
The conditions set out in Schedule 11 allow for the design of a wooden culvert able to support the legal load of 60 tons required for a CF3E truck.
Where a wooden culvert must be able to bear a higher load, the promoter must design it in accordance with conditions suited to that load. Because it is a culvert, it is not necessary to post the structure’s maximum load on a sign. However, according to the Commission des normes, de l’équité, de la santé et de la sécurité du travail (CNESST), all roads must be built in such a way as to ensure that all vehicles can travel on them safely.
