‘Difficult topography’ at Berriedale Braes improved

Traffic Scotland completed a project to remove the “difficult topography” on a hairpin bend at Berriedale Braes in August 2020.
At the time, a spokesperson for Traffic Scotland said: “The new road opened to road users on 21 August 2020 – which has improved journey times and road safety by removing the need for vehicles to slow down or stop to negotiate the bend.”
