M25 junction 25 improvementsRecently updated

Upgrade of junction 25 on the M25 to provide greater capacity.

Region:  South East
Start date:  2020-21
Cost:  £25 to £50 million
Status:  PLANNED
Type:  Major Scheme
End date:  TBC
Programme:  

Progress report

Public consultation

We have developed the scheme using feedback from the public consultation we held from January to February 2017.

We proposed two options for improving junction 25:

  • Option 1 – extra lanes on roundabout and widen the A10 southbound approach
  • Option 2 – extra lanes on roundabout, widen the A10 southbound approach and M25 approaches, and provide free-flow left turn

Results from our public consultation:

  • 92% agreed that there was a need for improvement overall
  • When asked about key concerns relating to the junction improvements, most conerns were around congestion (95%), construction impacts (81%), and road safety (80%)
  • 77% supported Option 2 over Option 1

For more information read our Consultation Report

The preferred route is Option 2

Following an in-depth analysis of the work done to date and your feedback from our consultation, we announced in June 2017 that we will now proceed with Option 2. This will improve journey times through the junction and allow more capacity on the exit slip roads, reducing the likelihood of traffic queuing back onto the M25, particularly into the Holmesdale Tunnel, delivering major safety improvements.

What’s next

The next stage in the process is to hold public information exhibitions. We initially planned to hold public information events in early 2018; to allow us extra time to ensure the events will be useful and informative, we now plan to hold these later in the year.

We will update you again in summer 2018.

* The optimisation announcement by the Department for Transport (November 2017) has allowed us the opportunity to review the scheme taking the ‘start of works’ to 2020/21.

Why we need this scheme

Junction 25 is a nationally and regionally important road, connecting the M25 with the A10. Up to 6,300 vehicles per hour currently travel through the junction 25 roundabout at peak times, causing congestion and regular delays. The A10 southbound approach into the junction is also a congestion hotspot in Broxbourne.

Our research shows that if we don’t improve junction 25 by 2037, we can expect:

  • increased congestion and lengthy queues and journey times could double
  • average speeds could reduce by up to 30% through the junction
  • disruption would be more widespread following incidents
  • congestion would constrain future development and growth opportunities
  • uncontrolled deterioration to local air quality

Aims

Through this scheme, we aim to:

  • reduce congestion and delays at junction 25 between the M25 and the A10
  • increase capacity by widening both the roundabout and the A10 southbound approach
  • redesign the roundabout to improve safety and traffic flow
  • support future traffic demands, enabling development and economic growth
  • maintain access for pedestrians and cyclists and improve conditions where possible
  • minimise the environmental effects of this scheme on local air quality and noise
