M3 junction 9 improvements

Major improvements to the M3 junction 9 to allow free movement between the A34 and M3.

Region:  South East
Start date:  2021-22
Cost:  £110 million - £130 million
Status:  PLANNED
Type:  Major Scheme
End date:  TBC

Progress report

This project is a Nationally Significant Infrastructure Project (NSIP) under the Planning Act 2008. That means we must secure a different type of planning permission to build it, known as a Development Consent Order (DCO).

We’ll are considering all the feedback received while we consulted on the scheme during July and August. We will use the feedback to refine our proposed design of the junction. It will also help us understand more about what we must do to protect the local environment.

What's next?

We will produce a consultation report that will set out a summary of all the responses we received and show how our proposals have been informed and influenced by them. Our report will form part of our DCO submission and will also be available to the public.

We expect to submit our application for development consent by the beginning of 2020 and, provided it is granted, work will start in 2021.

Why we need this scheme

Junction 9 of the M3 connects south Hampshire with London, the Midlands and the North. It is also part of a key freight route.

Roughly 6,000 vehicles an hour use it during peak periods and it currently creates a bottleneck that causes significant delays throughout the day.

Traffic is particularly heavy between the M3 and the A34 with frequent queues on the northbound off-slip of the M3 which are a safety risk during peak periods. To reduce the queues there is more green time allocated to the traffic lights on the northbound off-slip of the M3 and the A34 link. This amended sequencing, in turn, causes lengthy queues on A272 Spitfire Link and Easton Lane during the morning and evening peak periods.

Aims

This new proposed layout aims to:

  • improve safety by reducing queuing and delays
  • reduce congestion and improve reliability
  • reduce the number of people affected by noise and improve air quality
  • improve conditions for non-motorised users - it would connect National Cycle Network Route 23 which is severed by the current layout
  • support economic growth - improving road capacity which will help create jobs, improve business and support the building of new homes
