They are doing far, far less damage than heavy trucks, such as semi tractor-trailers or even box trucks with significant weight inside. Even so, the goal here is to spend the resources to permit movement of goods and people... not to limit traffic to those vehicle types that do the least damage to the road. The road is there to be used, not admired. If you really want 0 damage, work toward legalizing hovercraft on national highways.
