The UK's new Hindhead Tunnel is now open to traffic. The €420 million (£371 million) tunnel runs under the Devil's Punch Bowl in Surrey and will reduce congestion, while boosting safety on the busy A3 route. The 1.8km tunnel has taken four-and-a-half years to construct and lies on the London-to-Portsmouth A3 road. The twin-bore tunnel is one of the longest in England and will be used by 30,000 vehicles/day. The new tunnel will allow the existing A3, between the National Trust cafe and Boundless Road, to be closed to through-traffic. The tunnel forms part of a 6.4km bypass of the Surrey village of Hindhead. The project will remove a major source of congestion thus benefiting motorists and the local community whilst also cutting pollution to preserve the Area of National Beauty that is the Devil's Punch Bowl. The scheme commenced in 2007 with the tunnel being dug the following year and has won awards for its innovations and safety record. The tunnel itself contains state-of-the-art safety features, including the UK's first radar-based incident detection system and 100% CCTV coverage. Another innovative addition was the inclusion of 2696 Astucia Hardwired Bi-Directional Studs which will stream light and guide motorists safely through the tunnel. In October 2010, 868 2696 Astucia Hardwired Bi-Directional studs were installed split equally between the two tunnel bores. The studs are bi-directional meaning they emit a full 180 °of illumination when switched from uni-directional to bi-directional delineation when in the contra flow mode.

    The low risk found for driving through the tunnel is primarily due to the low volume of traffic of around 11,000 vehicles/day and the ban on HGVs and the transport of hazardous goods. Unidirectional traffic, sufficiently wide lanes, emergency lanes and lighting are the main reasons for the very good result for preventive measures. The tunnel is monitored around-the-clock in a tunnel control centre manned by trained staff, and incidents are automatically reported to the control centre by video link. If neces

    High performance markings are among the safety products used to guide traffic safely, but they must be tested and checked. Patrick Smith reports. Road construction zones, zebra crossings, tunnels and areas with frequent fog are particular focal points with regard to road user safety. This is why manufacturers, authorities and contractors are always eager to use innovative road markings and special studs or, where necessary, lane control devices to assist both drivers and pedestrians in all conditions, parti
