Resurfacing work this week will cause closures on the A48 in Forest of Dean.
The improvement work through the village of Aylburton is taking place each day between the hours of 9am and 3.30pm until Friday February 13.
Traffic will be prohibited from using the road during these working hours for safety reasons due to the width of the road and the size of the machinery. Pedestrians and emergency vehicles will still be able to access the road.
A full diversion route is in place during the closure, which directs traffic from Tutshill via the B4228, and B4231 to Lydney.
Vernon Smith, Gloucestershire County Council's cabinet member for highways, said: "This is a well used road through the Forest and Dean and we know that everyone will benefit hugely once the resurfacing work has been complete. We would like to thank road users and the local community for their continued patience whilst we carry out these vital works."
County councillor for Aylburton, Alan Preest, said: "This resurfacing work will be great for the area and I'm sure local residents and businesses will welcome the improvements."
