Commuters face miles of diversions while work to improve a key road takes place.
The A33 Reading Road between the Taylor's Farm roundabout and Sherfield-on-Loddon will be resurfaced as part of the County Council’s multi-million pound road improvement programme, Operation Resilience.
The works are due to start on September 23 and are scheduled to finish on October 7. The works will be carried out over night in a bid to cut disruption.
The county council said the entire stretch of the A33 being resurfaced will be closed to traffic from Monday to Friday between 8pm and 6am and closed at all times at weekends.
Residents and businesses will be given access during the closures.
A diversion route will be in place during the closures via the A339, A30 and B3349.
Operation Resilience is the second part of the county’s seven-year plan to weatherproof the roads damaged in the freezing winter in 2009.
The first phase, Operation Restore, cost £12.5m and was completed in November last year. The scheme carried out high priority repairs on badly damaged roads.
Operation Resilience includes the resurfacing of roads, together with drainage and improvements. The project aims to make the roads cope with freezing conditions are prevent potholes forming.
Councillor Mel Kendal, executive member for environment, said: “We are sorry for any inconvenience caused during these essential works.
“We recognise that while road works are carried out they can be frustrating for those affected. This is why we are only carrying out the works on the A33 at night and during weekends when traffic is at its lightest. This approach does mean however that the works will take slightly longer than had the road been closed for the entire duration.
“The A33 is one of nearly 400 sites on roads and pavements that are being targeted in the first year of our ambitious Operation Resilience programme.
“Operation Resilience is the county council’s long term strategy designed to make Hampshire’s roads more resilient to the effects of extreme weather and increasingly heavy traffic and recognises the importance of good roads for the county’s economy.”
