A Derbyshire road will be closed for at least six months after repeated landslips made it unsafe.
The B5056 at Fenny Bentley near Ashbourne has suffered from subsidence for several months and recent wet weather has made it worse.
County council engineers said they would inspect the area before giving an exact timeframe and cost for repairs.
They admitted there would be some inconvenience but insisted safety was their priority.
Signs of damage on the popular scenic route first appeared about six months ago in an area prone to landslides.
The county council said it had been monitoring the road closely and inspectors had now decided it had to be shut.
Councillor Chris Jackson, cabinet member for highways and transport, said: "Safety on our roads is our top priority and complex engineering measures are needed to repair the road and prevent it from slipping again in the future.
"We're working hard to resolve this problem and reopen the road as soon as we possibly can so we hope motorists will bear with us while this important work takes place."
Traffic is being diverted along the A5012 via Grange Mill to Newhaven, then the A515 from Newhaven to Fenny Bentley.
