Engineers have told Northumberland County Council that a road that has been closed due to a landslip could take more than a year to fix.
Experts say the ground under the B6344 near Rothbury is still moving and that more slippage is likely.
They say that the road will remain closed until it is reconstructed - which could cost more than one million pounds.
A landslip has caused part of a road to collapse near Rothbury in Northumberland.
The damage to the B6344 happened on Boxing Day.
Concrete barriers have been put in place to prevent drivers from using the road.
The land is still moving, and diversions have been set up.
The road between Rothbury and Pauperhaugh is expected to remain closed for several weeks.
