Headline: Cameras inside Waterview Tunnels to ensure safe speeds
Safety cameras have been operating in enforcement mode at the entrances and exits of the twin tunnels since they were opened in July 2017. The safety cameras inside the tunnels have also been monitoring travel speeds since July 2017, and will now be used to enforce the 80km/h speed limit inside the tunnels themselves, while the cameras at the tunnel entrances and exits will be switched off.
