Northumberland County Council has said that a road closed by a landslip in December 2012 could remain closed for a further two years despite the recent completion of the second phase of ground investigation.
The B6344 near Rothbury was closed on Boxing Day last year after part of the road surface collapsed.
Work to investigate the problem was complicated by the location of the landslide within a Site of Special Scientific Interest, as well as on-going ground stability issues and poor ground conditions. “The drilling operation has experienced many difficulties due to the ground continuing to move and because of the great depth of very soft material,” said the council in a statement.
Groundwater and ground movements will be monitored over the next six months. The council has said that it hopes to appoint a contractor to start developing the design to stabilise the area during this period but has warned that it could take up to two years to complete the work.
