I believe that the studs on the kerb at Barrowby bridge are illegal,they should be at least 3 feet from the road edge.
Whether they are or not, they do no good. They don’t stop vehicles that slightly misjudge the turn so they don’t protect the railing or people on the footpath. They only damage vehicles and that causes disruption and a lot of expense. They should be removed and ether a kerb built at least eighteen inches high or a continuous metal barrier put up.
