Typically, each winter the region experiences a freeze-thaw cycle that weakens roadway surfaces and undermines the sub-structures, requiring the implementation of weight restrictions to reduce the amount of damage. Seasonal weather conditions vary from year-to-year and dictate the extent of the restrictions and when they go into effect. Typically, these restrictions do not apply to the average car or pickup truck. However, commercial and construction vehicles may need to lighten their loads in order to comply with the restrictions.
