Question

where does the snow come from?what happens to the bridges then?​

Answer 1

Answer:

While the road surface also loses heat to the air, it has a heat source to compensate for that loss and it does not have exposed sides. The ground beneath the road surface provides heat to the road. This explains why ice and snow may accumulate more rapidly on a bridge surface than the road connected to it.
