A trip through the Saltash Tunnel and over the Tamar Bridge.
The 35-year-old tunnel will have its tunnel and traffic control system refurbished, along with the electrical distribution, lighting, fans and electronic signage. Most of this work will take place in 2024.
The scheme will see close to 5,000m of cable installed inside the 410m tunnel on the A38 in the county of Cornwall in England.
Overall design of the new incident detection system is to provide quicker detection of vehicle fires and other incidents, and integrated control systems are from PDS – Paul Ducker Systems – and includes smoke detectors from UK firm SICK Sensor Intelligence and SmartVision fiber-optic temperature sensing systems from AP Sensing in Germany.
Each day, more than 38,000 motorists use the tunnel that was designed by Mott, Hay and Anderson, built by Balfour Beatty and has a design life of at least 100 years.
