On the south (Southwark) side of the bridge just before the central section there is a very prominent ridge approximately one metre away from the kerb and running parallel to the bridge for some 30 metres. It is located exactly in the path of cyclists crossing the bridge who can be knocked off as they cross the ridge in either direction. In the dark and in the wet the ridge is very hard to see and cyclists may not see the ridge. The fault has been reported repeatedly in the course of more than 2 years to the local highway authority but no action has been taken. Can the highway authority explain why the ridge has not been removed?
