One local to me in Kingston upon Thames.

The thing about this is the bridge is 3.6m in height and the direction
it was travelling in has three signs stating that, one on each side of
the road before the bridge and one on the bridge itself.


Notices only reduce the bridge-bash-rate, so if a bridge gets more than
one bash a year they put up a gantry to be bashed so they don't have to
stop rail traffic until the bridge can be inspected.

Example, also local, the rail bridge over Hersham Road, Walton-on-Thames


When Hersham Station bridge was repaired, IIRC the gantry was not replaced.
