Charing Cross tunnel to trial innovative icephobic coating


As part of Transport Scotland’s strategic trunk road management programme, Scotland TranServ will install an innovative new icephobic coating on the M8 Charing Cross tunnel

The new icephobic coating on the M8 Charing Cross tunnel aims to help tackle the potential of icicles forming under extremely cold temperatures

During the winter of 2017/18 and particularly during the Beast from the East, it was necessary to implement emergency closures of the trunk road in order to clear the icicles, maintaining safety for road users.

Brian Coyle, Scotland TranServ’s assistant network bridges engineer, said: “The extreme temperatures of recent winters led to a number of issues with icicles forming on the underside of the Charing Cross tunnel. On several occasions, it was necessary for our Operations team to close the motorway in order to clear the forming ice from the roof and protect the health and safety of drivers.

“Scotland TranServ has been involved in extensive consultation with the local authority, emergency services and key stakeholders to carefully schedule this three-week programme of work to have minimal impact on commuters and businesses, avoiding peak holiday periods, busy weekends and major events. Traffic management will only be implemented once traffic flows are sufficiently low.”

In order to install this new icephobic coating, it will be necessary to implement a series of overnight closures of the M8 at Charing Cross.

Works will last for approximately 3 weeks. Access will be maintained for emergency service vehicles throughout. Local diversions will be in place overnight only during this programme of work. Drivers are advised to allow extra time for their journeys.
