Why Do Bridges Freeze First?

2/10/2021 (Permalink)

It may not snow very often here in Alabama, but we sure do see rain that freezes over night every once in a while. You have seen road signs advising that bridges freeze before roads, but do you know why? Having open air underneath the bridge means the cold air surrounds the bridge both above and below. We thought this was such an interesting fact and one that we needed to share here on our blog. We learned this thanks to the National Weather Service!

Additionally, bridges don't freeze evenly. An area of the bridge may be under direct sun light and have no ice, while the shaded area is covered in ice. If there’s even the chance that a bridge might be frozen, SLOW DOWN! And do it before you cross the bridge — changing speed on ice is dangerous. We always want our local community to stay SAFE any time of year!
