Slope stabilisation work above the portals to Beaminster Tunnel in Dorset has been successfully completed and Dorset County Council (DCC) has said that the route will reopen today.
The tunnel has been closed since 7 July 2012 when landslides occurred above both portals and the debris at the northern end was later found to have crushed a car, killing the two occupants.
Can Geotechnical has been working on stabilising the slope using soil nails since April this year to a design by Parsons Brinckerhoff, and over 800 soil nails and debris netting have been applied to the slope.
DCC has said that it plans to reopen the road to two way traffic from 10am today but may need to place temporary traffic lights on the route as main contractor Raymond Brown is still working on the project.
The £2.1M project was initially delayed by complex land ownership issues and bad weather, which prevented access due to the steepness of the slopes. DCC cabinet member for environment Hilary Cox said: “It has been a very complex project and we have had to overcome a number of difficulties. It has been a test of our engineering skills to find long-term solutions to make sure the land around the tunnel is stabilised for the safety of road users.”
