One of the main routes through the Forest will be closed overnight for a month for improvement work.
The closures for resurfacing will be carried out from 7pm to 7am between Edge End and Lower Berry Hill from tomorrow (Thursday, July 19).
The work will run until Monday, August 20, excluding weekends, and be carried out in two phases to help maintain local access.
Gloucestershire County Council says the work is necessary because the road has reached the end of its life.
Some 2,760 tonnes of material will be put down over a distance of 3,050m – nearly two miles.
Cllr Terry Hale, (Con, Drybrook and Lydbrook), said: “I’m delighted that another three-kilometre section is being resurfaced so soon after the Nailbridge to Plump Hill section.
