The maintenance work, which will require some overnight closures, will include gully cleaning, road sweeping, sign cleaning, manhole repairs and maintenance of structures.
Survey work, drainage repairs and resurfacing around Trago Mills and between Bodmin Parkway and White Lodge will also be completed within the closures, as well as safety improvements, including new signs and road markings, between Twelvewoods and Carminow.
Highways England Asset Delivery Manager Julian Strong said:
We have planned the work carefully so we can undertake a variety of different schemes whilst the road is closed.
Adjacent landowners have also been invited to take advantage of the road closure in order to prune trees and clear vegetation safely.
We’d like to thank drivers and local residents for their patience whilst we carry out the works and advise people to allow slightly extra time to complete their journeys.
For the safety of drivers and our workers closures will be in place between 8.30pm and 6am between14 to 18 November and 21 to 25 November. Clearly signed diversion routes will be in place throughout the work.
Stabilisation works will also be needed within the Glynn Valley early next year to ensure this section of the A38 stays safe and reliable for many years to come. Details of these works will be announced as soon as the programme has been finalised.
