    M271 Redbridge roundabout fully opens to traffic

    Representatives from Highways England and Southampton City Council met to mark the official opening of the M271 Redbridge roundabout now being fully open for traffic.  The scheme aims to improve the journeys for drivers visiting Southampton as well as improve the safety and appearance of the area for the local community.

    The multi-million-pound scheme has brought a number of important improvements including a new free flow lane going into Southampton, new traffic lights on the roundabout, and an additional lane allowing drivers to exit Southampton much quicker. These improvements are complemented by a new pedestrian footbridge, additional acoustic fencing and new planting to improve the environmental impact of the roundabout for local residents.  

    Highways England managed the scheme on behalf of Southampton City Council with Interserve constructing this technically complex project.  

    As well as making connections easier for drivers coming in and out the city of Southampton, there are also improved features for pedestrians and cyclists.  The scheme worked closely with members of the community including a locally designed mural by the pupils of Redbridge Community School which decorates a newly improved and much safer subway due to the scheme’s works.   There have also been 70 new trees planted, numerous wild flower meadows and the planting will continue over the coming few weeks.

    Consultation on the introduction of 40mph and 50mph permanent speed limits on the M271 southbound carriageway

    We are seeking comments on a proposal to introduce 40mph and 50mph permanent speed limits on the M271 southbound carriageway between junction 1 and Redbridge roundabout, including part of the southbound on-slip road at junction 1. 

    We would specifically like to hear from those who would be impacted on how the proposal on how it could affect you, your organization or those you represent.  It is important to note that this is not a consultation on the actual policy of using speed limits generally, we are therefore seeking your views on the proposal set out within this document. 

    The consultation period is between 23 November 2020 until 20 December 2020.

    Upcoming works

    From Monday 19 to Friday 24 October, we'll be installing new acoustic fencing at various locations during daytime hours. At some times this may be noisy and we apologise in advance for this. We will do our best to minimise any disturbance caused.  We hope that the end result will result in be a much quieter roundabout for local residents.

Project information

Overview

We announced our recommended design for this scheme, referred to as our “preferred route”, in 2017. When we decided on this route we took into account the feedback you gave us during our public consultation in 2016.

For the preferred design, Redbridge roundabout will include the following:

  • a segregated left turn lane for traffic leaving the M271 and going towards the port. This includes moving a toucan crossing further from the roundabout to increase visibility and improve safety
  • a new replacement pedestrian footbridge
  • a new lane for traffic heading north on the M271 from the Port and City
  • refurbishment of the northern subway at Gover Road
  • closure of the southern subway - this will be compensated for by a new toucan crossing over the roundabout carriageway
  • a new southern cycle path
  • paths to support all pedestrian and cyclist movements across the roundabout

Before developing our initial proposals for the Redbridge roundabout, we looked in detail at the problems that road users currently experienced, as well as the opportunities that an enhanced junction would create.

The M271 is an international route and is used by large volumes of heavy goods and holiday traffic. Long distance traffic from the M27 and M3 and conflicts with local traffic from Southampton City. We predict that the existing M271 Redbridge roundabout will suffer from congestion and long delays in the future if additional capacity is not created.

The aims of this scheme are to:

  • deliver a more free-flowing network by relieving traffic congestion, improving capacity and reducing journey times
  • provide a safer and more accessible environment for pedestrians and cyclists
  • enhance the environment through public space improvements and landscaping
  • reduce road traffic noise and tackle air quality by enabling free flowing traffic and resurfacing carriageways
  • improve equality, diversity and inclusion for all users by improving pedestrian, cycle and bus facilities, and enhancing overall safety and security at the roundabout
  • support economic growth by improving access into Southampton
