B4025 Cat's Eyes

I don't know what's going on with the B4025 Worcester Road running out of Stourport but as you approach the Sandy Lane Industrial Estate turn off all the cat's eyes embedded in the road surface seem to have raised up. They're not newly fitted ones as the metal surrounds are rusted, but they're all sitting proud of the road by about an inch with right-angled metal brackets.

Turn off and it's like driving over cobbles.
