Progress report

Our consultation ended on 28 February 2017.

Thank you for all your comments and responses during the consultation. All views and comments will now be considered and summarised in our public consultation report.

What’s next

We will:

  • make sure potential impacts on the community and environment have been fully considered
  • ensure the final scheme design considers all relevant responses where applicable
  • ensure the final environmental statement takes into account impacts and mitigation measures you have told us about
  • record how we have considered feedback to develop the scheme further within our consultation report

We will now produce more detailed designs for the scheme, which will involve a second public consultation. You will be able to give your views again and influence the development of the designs. We will let you know more about this nearer the time. Alternatively you can subscribe to our page and be automatically notified of any updates.

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.

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
