Overnight lane closures on Queensferry Crossing: 31 July & 1, 2 August
Traffic on the Queensferry Crossing will be restricted to a single lane in each direction between 22:00 and 05:00 on the nights of Friday 31 July, Saturday 1 August and Sunday 2 August.
This is to allow Transport Scotland’s operating company Amey to install ice sensors on the bridge at deck level and at the tower tops. These sensors will help to provide early warning when conditions are conducive to ice accumulating on the structure.
The lane closures will also be used to remove LiDAR equipment that has been used to carry out a survey of wind behaviour around the bridge.
These lane closures are not expected to cause any significant delays.
Mark Arndt, Amey’s Account Director for the Forth Bridges Unit, said: “We know from previous incidents that ice can accumulate on the Queensferry Crossing’s cables during a very specific combination of temperature, humidity, wind speed and direction.
“These new sensors won’t prevent ice forming on the cables, but they will provide us with significantly enhanced data to detect, monitor and understand the specific climatic conditions that cause this phenomenon.”
The safety of workers remains a top priority during this essential maintenance project. Physical distancing protocols, in line with Scottish Government guidance, will be in place to ensure all on-site personnel remain safe throughout the duration of the project. Thorough risk assessments will be carried out and cleansing stations will be implemented on site.
Transport Scotland and Amey fully recognise the importance of a safe and reliable trunk road network, particularly during the Covid-19 outbreak, and it is vital that essential maintenance works are carried out in order to maintain the integrity and safety of these routes. A number of maintenance projects have been identified as essential and will be prioritised over the coming weeks.
Please note that all schemes are weather dependent and may be cancelled or rescheduled if conditions are not favourable.
