What does acid rain do to your roads and highways and bridges?
It also causes our roads, highways, and bridges to corrode and become weaker. This is a huge safety hazard not only for roads and highways, but also for bridges because if a bridge is weak, it will collapse. It costs a lot of money to keep replacing the roads, highways and bridges, and it comes out of our tax money.wanker wanker wanker hahaha lol

Why do concrete bridges deteriorate?
