videocameras in the tunnel to detect the speed of traffic, as well as fire and smoke. Temperature sensors were installed at short distances throughout the tunnel, monitored from a central control post. Fire hydrants were installed every 130 m, fed from large water tanks. There are 11 safety points along the tunnel, equipped with telephones and loud speakers connected to the control room, with a separate ventilation duct to supply fresh air. These are separated from the main tunnel by two fire doors; the outer door closes automatically when the temperature in the tunnel reaches a certain level. Finally there is a ‘thermal gate’ system at each entrance to identify any overheating vehicles.

328:. Originally planned as an 8 m (26 ft) wide rescue tunnel, an agreement was reached in 2012 to open the new bore to traffic towards France while converting one lane of the existing bore into an emergency lane. The breakthrough occurred on 17 November 2014. The new bore is due to open to traffic in the autumn of 2023. As there will still be a single lane for each direction (the other lane being an emergency lane), the capacity of the tunnel will remain unchanged. Both bores will be connected by a series of passages, five of which can be used by emergency vehicles.
