It has been confirmed the overnight road closures will start on Saturday 30 July.
Major works to rebuild the A3088 Cartgate Link Road near Yeovil have been confirmed to start later this month.
Somerset County Council will strengthen and improve 2,300m of carriageway, using innovative methods to recycle 70 per cent of existing road material.
By using this process, work that could have taken several months should be completed in just five weeks, reducing disruption on one of Somerset’s busiest roads. It will also keep costs down and have environmental benefits by vastly reducing the need to transport materials.
Eleven different machines will be used in the three-step process of pulverising and compacting the old road, then tarmacking a new surface.
Roadworks are due to begin on the week beginning Monday 25 July, using overnight road closures between 7pm and 7am to minimise disruption as much as possible. Temporary traffic lights will also be needed during the day so drivers are advised to allow extra time or consider using alternative routes.
Cllr David Fothergill, Somerset County Council’s Cabinet Member for Highways, said: “The Cartgate is a very busy road so we’ve had to look carefully at how best to carry out these much-needed improvements without causing too much disruption.
“This road recycling technique is not suitable for all jobs but can be very effective in the right location. It will be cheaper, greener and quicker than other methods, but we will still be excavating deep under the road to resolve the underlying weakness and prevent future problems with potholes.
“We’ve timed the work to take place at night and during the school holidays when roads are quieter, but please be aware of the works and plan your journeys carefully.”
Roadworks by Wessex Water will also be taking place on Lysander Road on the week beginning Monday 25 July. This will require the closure of Lysander Road from Bunford Hollow to the Horsey Roundabout in an easterly direction only.
The two schemes were planned to take place at the same time to reduce the overall disruption to the town.
A spokesman for Somerset County Council said: “There is no perfect time to carry out roadworks – any work that involves traffic lights or a closure will lead to some disruption. What we try to do is keep this to a minimum through careful planning and co-ordination.
“In this case, we’ve worked closely with Wessex Water to plan both schemes to take place concurrently to avoid disruption over a much longer time period. We’ve also timed both schemes for the school holidays when roads are quieter and considered other factors – for example, the closure of the Cartgate Link Road, which is having multiple works undertaken, should reduce the traffic volumes on Lysander Road because vehicles will be diverted away from the area.
“The co-ordination of roadworks is complex and we also have to consider future demand for roadworks from utility firms and developers, as well as our own improvement works.
“Both schemes have been well publicised and we would encourage motorists to plan their journeys carefully and allow extra time while work is underway.”
