Asphalt wears out just like everything. UDOT and other states have a lot of data from research and development from the last several decades to help them anticipate when a highway is going to wear out. If they don’t resurface in time, we would have to drive with potholes, and deteriorated road shoulders, making for very dangerous and unsafe conditions. Kinda like watering your trees before they die.
You also mention about traffic roaring through town. That would not be a problem if you idiots wouldn’t have voted against a bypass several years ago.
Some people are never happy and are against everything, even if they could benefit.
