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
Cost:  ¬£50 million - ¬£100 million
Status:  PLANNED
Type:  Major Scheme
End date:  2023
Programme:  

Progress report

We completed a non-statutory public consultation in early 2018. The results of the consultation can be viewed in our Public Consultation Report which is available, together with our Preferred Route Announcement brochure, in the 'Media and Documents' section below. The project has now proceeded to the preliminary design stage.

If you have any questions about the project then please contact us via the scheme mailbox:

What's next?

We'll carry out intrusive surveys in order to obtain the necessary data required to further refine the design and provide important information on ground conditions.

The scheme will be taken through the necessary planning and statutory procedures. In late spring 2019 / early summer 2019 we'll go through a Statutory Public Consultation process.

Why we need this scheme

M3 junction 9 is a key transport interchange which connects South Hampshire (facilitating an intensive freight generating industry) and the wider sub-region, with London via the M3 and the Midlands/North via the A34 (which also links to the principal east-west A303 corridor).

A significant volume of traffic currently uses the grade separated, partially signalised gyratory (approximately 6,000 vehicles per hour during the peak periods) which acts as a bottleneck on the local highway network and causes significant delays throughout the day.

Northbound and southbound movements between the M3 and the A34 are particularly intensive, with downstream queues on the northbound off-slip of the M3 often resulting in safety concerns during peak periods. To overcome queuing on the off-slip, additional green time is allocated to the northbound off-slip of the M3 and the A34 link, resulting in the development of lengthy queues on A272 Spitfire Link and Easton Lane during the morning and evening peak periods respectively.

Aims

This scheme will aim to:

  • improve safety by reducing queueing 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 sub-regional economic growth, unlocking road capacity for jobs, businesses and new homes
