Seasonal Load Restrictions and Road Closures
Many gravel roads are placed under a 5 tonnes-per-axle load restriction in the spring of the year. This is to help protect the integrity of the road when it is in a particularly sensitive state as the ground frost thaws. Signs are erected to notify road users of this restriction. Below is the type of sign we use for this purpose, which is from Book 5 of the Ontario Traffic Manual.
Load weight will be restricted on most secondary roads throughout the City in accordance with By-Law 2005-077, at the discretion of the Director of Public Works. Load restriction periods are potentially between October 1 and May 31 annually. Notices will be issued each year to define restriction periods based on seasonal weather conditions
Restrictions are typically put into place during the spring thaw, when road damage is most likely to occur due to heavy loading. This program identifies and imposes load restrictions on roads, or portions of roads that are weakened by excess water in the road base. Once the road has been determined to be structurally sound, load restrictions may be rescinded.
Due to changing weather patterns, the roads affected and the duration of the restricted period may change.
There are currently load restrictions throughout the municipality.
