Progress report

The Public Information Exhibition period closed on 24 June 2019.

The Public Information Exhibition was announced from 20 May 2019 onwards following on from the previous communication milestones. The purpose of the PIEs was to:

  • inform stakeholders of the progress we had made since the PRA
  • describe what would happen next
  • share our initial understanding of potential traffic impacts during construction
  • provide further opportunity to meet the team and ask any questions

The majority of feedback was regarding the following themes/topics

  • Construction: when the work will start, finish and its duration
  • Discounted options/design decisions
  • How the scheme will operate

What’s next?

We'll now progress with the detailed design of this scheme through the course of 2020. Scheme construction will then begin in winter 2020-21. Email updates on progression during scheme construction will then be sent to all those who have registered to receive project updates with the scheme webpage.

* 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
