Landslip-hit Rothbury road to be closed for nine months
The main road into a Northumberland town will remain closed for at least nine months after it was cracked in four places by a landslip.
Northumberland County Council said the B6344 at Rothbury was "highly unstable" after it was damaged on 26 December.
Engineers estimate that repairs along the 300m stretch could cost up to £3m.
Business owners in Rothbury said they were concerned about the effect on trade.
A diversion through Longframlington adds four miles (6.5km) to the usual journey time.
The council said work would be complicated by the fact the area is designated as a Site of Special Scientific Interest.
Councillor Alan Thompson said: "We anticipate that it will be around three months until the site investigation and material testing has been completed and a preferred solution has been identified."
