Sutton Bank on the A170 between Helmsley and Thirsk is to close for a week from Monday 10 September for essential annual maintenance work.
This includes the inspection of the rock face to ensure it is in a sound condition. Osgoodby Lane, south of the A170, will also be closed and there will be no access to or from the A170 for Osgoodby Lane residents.
A diversion will be signposted along the caravan route through Ampleforth and Coxwold. During the closure access to premises on Sutton Bank will be maintained whenever possible, but there may be times when it is restricted.
County councillor Don Mackenzie, executive member for highways, said: “The county council will be making every effort to complete the work as soon as possible and to keep disruption to a minimum. We would like to apologise in advance for any inconvenience this essential work may cause.’’
Councillor Gareth Dadd, who represents the Thirsk division, said: “Sutton Bank is a key strategic route and therefore an important part of the county’s highways network. Making sure it stays in good condition is vital and we can’t do this work without putting a road closure in place.’’
