Improvements planned for busy M25 junction

A ‘vital upgrade’ which will improve journeys for hundreds of thousands of drivers using one of the busiest junctions on the M25 has been given the green light.

Transport Secretary Grant Shapps has today (Thursday, May 12) given the formal go ahead for improvements to junction 10, the interchange with the A3 at Wisley.

National Highways said the junction is one of the busiest in the country and experiences large queues and heavy congestion on a daily basis.

A spokesperson added, “It also has one of the highest recorded collision rates across England’s motorway and major A roads nationally; this project will reduce collisions by around a third.”

The busy M25 junction 10 is set for a major revamp which will help to improve safety, reduce collisions and cut congestion

The scheme will also involve some of the most extensive environmental work ever carried out by National Highways, restoring over 22 hectares of heathland as well as planting new woodland.

The spokesperson added, “The UK’s first ever ‘heathland’ green bridge will link walkers and cyclists to these important habitats for the first time.”

National Highways regional delivery director Chris Welby-Everard said, “We are delighted with today’s announcement which means we can now proceed with our project to improve the M25 junction 10/A3 interchange near Wisley.

"This vital work will improve safety and reliability for almost 300,000 drivers a day and generate more than 400 jobs.

“We are grateful to stakeholders for their continued engagement and contribution in the development of the scheme and will continue to work with them as we take the project forward.”

National Highways said the major improvements package includes a new elongated roundabout to increase capacity, four new dedicated free-flowing slip roads to reduce queuing between the M25 and the A3, widening the M25 from three to four lanes through the junction, widening the A3 from three to four lanes either side of J10 and improving the A245 at Painshill.

Better routes for pedestrians, cyclists and horse riders are also expected to be provided as a result of the work which is expected to start later this year.
