M27 Junction 3 Improvements
Part of our programme of improvements (generally with value <£10m)
The main construction is now complete.
Additional tasks, including landscaping, will be carried out over the coming weeks using overnight closures.
What is happening?
We will be carrying out work to improve the interchange where the M271 junction 2 meets the M27 at junction 3. This will include:
- widening of the M27 westbound exit slip-road to 3 lanes
- widening of the M271 northbound and southbound approaches to the interchange to three lanes
- removal of the eastern overbridge hard shoulder to allow three lanes
- adding traffic signals to the interchange
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.
View the Scheme Overview Plan for more information.
When and where is this happening?
Main construction began in January 2015 and is expected to be complete by the end of August 2015.
The scheme is located at junction 3 of the M27, to the north-west of Southampton.
Why is this happening and what will it cost?
The M27 junction 3 is a major route into Southampton and the Docks. The junction currently suffers from significant congestion on both the northbound and southbound approaches of the M271 and the M27 westbound exit slip road during peak periods.
This congestion and delay has a detrimental impact upon current economic activity, and will continue to restrict and discourage economic opportunities and the potential for growth within the surrounding area..
The works will cost approximately £2.3 million.
How will the scheme be carried out?
The work will be carried out during both night and day shifts. There will be overnight closures of sections of the interchange, with signed diversion routes, to allow work to be carried out safely. During the day, there will be speed restrictions and narrow lanes at the interchange.
Narrow lane traffic management will be in place with speed limits.
Please allow additional time for your journey.
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 interchange

How will you manage traffic?
Narrow lane traffic management with a 50mph speed limit will be introduced on the M27 junction 3 westbound exit slip road, on the roundabout and on the M271 approach roads to the junction.
The work will require some overnight closures (10pm-6am) of sections of the slip roads, approach roads and the roundabout.
Signed diversion routes will be in place during these times.
Please allow additional time for journeys using junction 3.
Will there be diversions?
During closures, clearly signed diversion routes will be in place.
The diversion route south of M27 junction 3 will be via A35, A326 and junction 2. North of M27 junction 3, the diversion route will be via the A3057, A3090, A36 and junction 2.
