Width restrictions and traffic light controls are to be installed on a Dorset road to allow it to be reopened after more than a year of closures due to landslide risks.
The Blandford to Shaftsbury C13 was closed through Dinah’s Hollow near Melbury Abbas last May following a reports that should the steep slopes were unstable and presented a potential hazard to road users.
Parsons Brinckerhoff has developed a stabilisation scheme using a soil nailed solution for Dorset County Council (DCC), which was initially planned to be completed under full closure of the road. The reopening was considered following a full risk assessment of the impact of the closure on surrounding roads, communities and businesses compared to the safety risk over longer timescales than initially expected to complete the proposed stabilisation works.
According to a DCC statement: “The cabinet decided to temporarily open the road with traffic management to reduce the risk of a car being engulfed if a slip happened. Placing continuous lines of barriers either side of the centreline and directing a single lane of traffic down the centre of the road, controlled by traffic lights will move vehicles away from the bottom of the slopes”.
