Landslips have already caused the demolition of bungalows at Knipe Point
A stretch of coastal road affected by landslips in North Yorkshire has been closed after further slippage.
Last month, the county council said the old A165 Filey Road, linking Cayton Bay and Osgodby, would have to close.
The council said a decision to close the road permanently was taken after heavy rainfall led to further movement. Diversions have been put in place.
The landslips have already led to the demolition of three cliff-top homes at nearby Knipe Point on safety grounds.
The council said it had undertaken a land-stability assessment which had confirmed the sandy clay scarp face was now within a few metres of the highway.
It said it was "very fortunate" the new A165 Scarborough to Lebberston diversion was completed last year.
A spokesman said: "It is hoped that the impact on highway users will be minimal given that traffic volumes on this old Filey Road are very low, albeit local access to the Osgodby area from the south will be lost.
"Significant engineering works would be required even to temporarily stabilise the highway, and given the topography and geology of the area the county council is not in a position to maintain the route."
Although the road is closed to vehicles, pedestrian and bridle access will be maintained on the south side of the highway.
