Do bridges freeze first?
Bridges do indeed freeze before roads, and there’s a good reason why. First, cold air surrounds the surface of a bridge from above and below. This means that bridges lose heat from both sides. Bridges have no way to trap heat, so they will ice rapidly as soon as the temperature decreases to the freezing point.
