What could have lowered the actual clearance under a bridge or overpass since its height was posted?

Answer options

Why

Each new layer of pavement raises the road surface, so the real space under a bridge can end up smaller than the posted height; packed snow can have the same effect. If you are not sure your vehicle will fit, go slowly or take another route.
