HADECS Speed Camera on A316, St Margaret's / Richmond (40mph)

40mph speed limit HADECS speed camera

This HADECS 3 speed camera is located on A316 near St Margaret's / Richmond in Greater London, monitoring east and westbound traffic with a 40mph speed limit.

Updated Gatso cameras to two HADECS camera systems on each lane in each direction from Richmond to St Margaret's over twickenham bridge. One before bridge (west) and one by bridge over road at Richmond. Same in other direction. Nice.
