The works will be carried out between 8pm and 6am the following morning and involve the closure of the road for eight miles in both directions between Turfdown Cross and the junction with the A390 at Dobwalls.
This closure is to allow road maintenance and improvements to be carried out in a safe manner.
Diversions will be in operation and will be signed in advance. Drivers should note and follow the symbol signs. Access for local residents, Bodmin Parkway Station and the Halfway Public House will be provided.
The Highways Agency’s project sponsor, Mike Hillier, said:
This work will maintain road safety by replacing the road surface and improving the drainage system.
It is being carried out at night to cause the least possible inconvenience but we would advise road users to allow slightly longer for their journeys.
Further overnight maintenance works will be taking place on the A38 in the Glynn Valley between the nights of Monday 10 November and Friday 14 November.
Westbound traffic will be diverted at Dobwalls to take the A390 to the junction of the B3269. Traffic will follow the B3269 to the junction with the B3268 and follow this road to the roundabout junction with the unclassified road south of Bodmin. Traffic will then follow the unclassified road towards Turfdown Cross and rejoin the A38. Eastbound traffic will be diverted to follow this route in the opposite direction, rejoining the A38 at Dobwalls.
For vehicles over 20 tonnes or greater than 14’9’’ height:
Westbound vehicles will be diverted at Carkeel to take the A388 north to the Tavistock Road Interchange at Launceston where traffic will travel west on the A30 to rejoin the A38 at Bodmin. Heavy Goods Vehicles travelling eastbound will be diverted to join the A30 eastbound at Bodmin and use the above diversion in the reverse direction to rejoin the A38 at Carkeel.
Access to Bodmin Parkway Station:
Traffic will be diverted via Respryn and Turfdown roundabout
Cyclists will be unable to use the A38 throughout the scheme, day or night, owing to the nature of the road surface and the narrowed lanes for traffic during the day.
All diversion routes will be clearly signed, with many of the signs being the symbol type. Drivers should avoid trying to use satnav devices as these will merely direct them back to the closed road.
