Dorset County Council (DCC) has said it will present details of the options that would allow it to reopen the Beaminster Tunnel, which has been closed since the fatal landslide on 7 July, at a public meeting on 18 October.
DCC confirmed that the ground investigation was successfully completed and testing is now underway on soil samples from the boreholes. The foundations of the tunnel headwalls were also investigated during the site work.
Data from the investigation is expected to be available by the end of the month and will allow DCC to proceed with design and cost analysis for a long-term solution. Cabinet holder for highways councillor Peter Finney said: “We are working extremely hard to get the information we need to make the right choice for Beaminster Tunnel.”
The council has said that options which are likely to presented at the meeting in Beaminster include slope stabilisation, regarding of the slope, extension of the tunnel or removal of the tunnel by either a cutting or permanent bypass route.
