Schedule 11
Conditions to be met when constructing, improving or repairing wooden culverts
1
Additional information
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.
The decision tree below can be used to decide on the type of structure that must be installed to cross a watercourse.
