Highways England has announced a £1.1 million new technology scheme at the A38 Saltash Tunnel in Cornwall.

The tunnel uses a tidal flow, which adjoins the Tamar Bridge using advanced control systems to manage traffic travelling in and out of Cornwall and Devon on the A38.

Work starts this coming weekend and will involve the installation of CCTV and an emergency public address system which ensures drivers’ safety in the tunnel, and along the A38 from St Budeaux to Carkeel Roundabout.

The CCTV will allow operators to monitor traffic flows and adjust the configurations of lanes within the tunnel and over the Tamar Bridge crossing to help ensure journey reliability for drivers.

The emergency public address system will allow operators to convey both pre-recorded and live messages to tunnel users in emergency situations as required.

 

The new equipment, the same used by Transport for London, replaces a system which has been in use for 12 years.

Nineteen new digital CCTV cameras with improved low light capability will be installed as well as ten speakers specially designed to give clarity to messages inside tunnels.
