Improvement Scheme

Part of our programme of improvements (generally with value <£10m)

Cost:  £8 million

Managed by:   Area 3


Main construction is now complete and junction 5 is fully open.

Landscaping and fencing works will take place within weekday off-peak lane closures until mid-October

What is happening?

We are carrying out works to improve traffic flows at junction 5 of the M27. Work will include:

  • widening of the M27 eastbound exit slip road, Stoneham Way and the A335 Wide Lane to three lanes
  • sections of the northern half of the roundabout will also be widened to three lanes
  • construction of a segregated left turn lane from A335 Wide Lane onto the eastbound M27 entry slip road
  • installation of new traffic signals on the northern section of the roundabout

The works are a continuation of the previous scheme constructed in 2009 by Hampshire County Council to improve the M27 westbound exit slip-road and A335 Stoneham Way.
These works are part of the national Pinch Point Programme. The Pinch Point Programme forms part of the UK Government's growth initiative, outlined during the Chancellor’s Autumn Statement in November 2011.

When and where is this happening?

The main construction work started in August 2014 and will be completed by the end of August 2015.

M27 Junction 5 is located to the south-west of Southampton Airport, near Eastleigh in Hampshire.

Why is this happening and what will it cost?

The M27 junction 5 regularly experiences significant delays during peak travel periods. This has a direct effect upon accessibility in the area particularly in relation to Southampton International Airport and Southampton (Airport) Parkway Station, as well as Eastleigh town centre.
Delays at the junction also have safety implications in terms of the effective operation of the motorway and its exit slip roads.
The scheme will cost approximately £8 million.

How will the scheme be carried out?

The works will be carried out during both day and night. There will be overnight closures of sections of the junction, to enable works to be carried out safely. During the day, there will be speed restrictions and narrow lanes at the junction.

The culvert beneath Wide Lane will be widened to accommodate the additional lanes on the A335 Wide Lane.

What are the benefits?

As part of the Pinch Point Programme, this scheme aims to:

  • help to reduce daily congestion, particularly during peak hours
  • reduce journey times for the travelling public
  • boost the economic growth of the area
  • improve safety at the motorway junction

Details of scheduled roadworks are provided to help you plan your journey. Please note that works are weather- and resource- dependent and may need to be cancelled at short notice. This information is not updated in real time so please check Traffic England for current traffic conditions. Diversion timings are approximate and act as a guide only.

Will there be roadworks?

Work began on Monday 4 August with overnight (10pm to 6am) closures to install narrow lane traffic management:

Please allow extra time for your journey

How will you manage traffic?

Delays are expected during the scheme, and it is advised that you plan ahead of your journey to allow for extra time if travelling through these works.

During the works there will be lane closures on the M27 eastbound slip roads and traffic lights on Stoneham Lane and A335 Wide Lane during the works period, to allow the works to be undertaken safely. There may be overnight closures of the junction to allow resurfacing works to take place.

There will be a 50mph speed limit on the Junction 5 slip roads, and a 30mph speed limit on the roundabout, approach roads and Wide Lane while this work takes place.

Narrow lanes will be installed to maintain the flow of traffic across the junction and to create a safe environment for workers.

Will there be diversions?

 These are the proposed diversion routes whilst the works are taking place:
