During the spring thaw, City streets are weakened by water that becomes trapped in the gravel base below the pavement. The weight of vehicles can cause the road to bend, and if the surface is bent too far or too frequently, it cracks. As pavement ages, it becomes brittle and less able to withstand weight and movement and deteriorates at an accelerated pace. Weight restrictions are implemented each year in early spring in an effort to minimize the wear to the streets and to allow the base adequate time to stabilize. It is important to avoid deliveries and remodeling projects during this time.
