Jeremy, in UK legislation, the definition of 'traffic" includes pedestrians, people cycling, people riding horses, people herding animals in addition to mechanically propelled vehicles.At this moment in time Hammersmith Bridge is closed to certain types of mechanically propelled vehicles, it isn't "closed to traffic".Of course, that doesn't stop some people thinking that traffic only consists of motor vehicles but they aren't correct according to the legislation that governs roads in the UK.
