M27 Southampton junctions

Improvements to the M27 junction 8 and Windhover roundabout.

Region:  South East
Start date:  March 2020
Cost:  £130 million
Status:  PLANNED
Type:  Major Scheme
End date:  TBC
Programme:  

Progress report

Following the consultation, we’ve continued to develop the proposed route taking into account issues and alternative suggestions raised during consultation. We’ve also carried out some additional work to establish the solution that provides best value for money. This has led to the scheme being reassessed and we’ve now decided on a joint approach, working with Southampton City Council to deliver the improvements.

We’ll continue to progress the scheme at the M27 junction 8 and Windhover Roundabout, while Southampton City Council will now deliver improvements at junctions along the A3024 corridor.

Find out more about our preferred route.

What's next?

Now that we’ve announced our preferred scheme we’ll carry out further surveys and investigation to allow us to continue to design the scheme in more detail. Once we’ve completed this work we’ll hold some public events so that you can view the final design and ask any questions you may have.

Why we need this scheme

Safety is a key concern as 196 accidents were recorded from 2011 to 2015 between Windhover Roundabout and Northam Road Rail Bridge. 23% of these resulted in serious injury and 27% involved pedestrians or cyclists.

The M27 junction 8 was in the top 50 sites for casualties between 2009 and 2011.

The Bitterne Gating System, a series of linked traffic signals on the A3024 corridor, restricts access from many side roads and holds some traffic back on the edge of Southampton during the morning peak period.

Poor air quality associated with vehicle emissions is currently an issue on the A3024 Bitterne Road West. The local authorities are keen to make improvements to encourage more sustainable modes of transport such as walking, cycling or public transport in an effort to improve air quality and health.

Congestion at Windhover Roundabout is a combination of localised peak time (7am to 10am and 4pm to 7pm) traffic and rat-running to avoid M27 junction 8 tailbacks.

If traffic congestion and queuing is not addressed on the local network, planned housing and employment growth will be compromised and the impacts of poor air quality will continue.

Aims

The aims of this scheme are to:

  • support economic growth – contributing to sustainable economic growth by supporting employment and local residential development opportunities
  • improve connectivity and reduce journey times around M27 junction 8 and Windhover Roundabout
  • provide a safe and serviceable network – improving the safety record at M27 junction 8 and Windhover Roundabout (60 year look ahead assessment period)
  • provide a more free-flowing and reliable network – reducing congestion around the M27 junction 8 and Windhover Roundabout and improve journey time reliability and connectivity between east and west of the M27 junction 8 – Windhover Roundabout
  • provide a safe, accessible and integrated network – delivering capacity enhancements to the M27 junction 8 and Windhover Roundabout, while supporting the safe, accessible use of active travel modes for pedestrians and cyclists
  • provide an improved environment – seeking to prevent the worsening of air quality by reducing congestion and journey times along the M27 junction 8 and Windhover Roundabout and aiming to mitigate noise impact
