Future Southampton

Third Avenue - Major road improvements

Latest news - 5 July 2018 Update

A lack of space to use large machinery has slowed progress and phase 1 of the day time work is now planned for completion by 20 July (weather permitting).  We have drafted in additional resources and made an early start on phase 2 as work in this phase is also expected to take longer. 
The delay in completing phase 1 means that the one way system will remain in place in area 1 and area 2 until 20 July (See map) and then continue in area 2 until this section is completed which might now be early August.
There is a slight change to the overnight closures to fit around the planned upgrade and replacement of the traffic signals at the Millbrook Road West/Regents Park Road junction. Phase 3, overnight concrete laying in area 1, will now start from w/c 23 July. Phase 4 and 5 resurfacing the road overnight will then follow later in August. We are still planning to complete Third Avenue by early September. Please bear with us.
We are working with all those businesses with overnight operations to minimise any disruption. If you experience any access problems, please speak to our crew on site.


Resurfacing the full length of Third Avenue – from 25 June 2018 (ten weeks)

Balfour Beatty is working in partnership with Southampton City Council to manage the highways service across Southampton.  As part of this, Third Avenue is being fully resurfaced this summer and then within the next six months improvements will start to be made to cycling and pedestrian access, which we will be consulting on the details later in the year. 

The resurfacing work will take up to 10 weeks and has been planned so that it will be completed ahead of the Millbrook Roundabout full reconstruction, starting in October.

Day time restrictions (five weeks)

The resurfacing of Third Avenue will begin with ground preparation works to replace concrete sections and repair kerbs and drainage. Work will require Third Avenue to be closed one-way inbound (east-bound) in two phases starting from Monday, 25 June 2018 for up to five weeks (see map). 
  • Phase 1 working in area 1 will require the entire length of Third Avenue (both area 1 and 2) to be one-way for up to two weeks. 
  • Phase 2 working in area 2, will require Third Avenue to be one-way from Manor House Avenue to Regents Park junction for up to three weeks. 

Night time closures (five weeks)

After the ground preparation works, there will be up to five weeks of nighttime closures (8pm-6am, Monday-Friday including some weekends) for laying larger concrete sections and resurfacing. 
  • Phase 3 concrete laying area 1, will require area 1 to be closed overnight for up to two weeks. 
  • Phase 4, resurfacing area 1, will require area 1 will be closed overnight for up to one week. 
  • Phase 5 resurfacing area 2, will require area 2 to be closed overnight for up to two weeks. Work will be in smaller sections to allow for some access, dependant on where work is being carried out. We will communicate with those businesses directly affected closer to the time.
The timing of the phasing is indicative and weather permitting, if we are able to complete work earlier than planned this may bring forward the phasing timing. We will be sending email updates with changes and more details as well as providing updates on the website.

Cyclist diversions

Regrettably it is not be possible to maintain two-way cycling access when the one-way restrictions and overnight closures are in place and cyclists will be diverted to the north side of Millbrook Road West (more details will be available online). 

Pedestrian access

Pedestrian access will be maintained throughout via the pavements. For health and safety reasons pedestrians are not permitted into the segregated works area. If you require assistance, please speak with a site marshal.

Please bear with us while these important works are being carried out. We will always maintain pedestrian and emergency access to properties. During these works there maybe periods when vehicle access is not always possible. For health and safety reasons, pedestrians are not permitted into the segregated works area; if you require access please speak with a site marshal.

Third Avenue - Frequently Asked Questions (FAQs):

Why are we doing the work on Third Avenue now?

The timing is partly down to the deterioration of the road and availability of funding this year. The specific timing is to avoid conflict with other major highways work also planned to be undertaken on Millbrook Roundabout and Redbridge Roundabout in 2018 and 2019. 

Why is Third Avenue being made one way when work is only at one end?

To allow safe working areas requires initially the western end of Third Avenue to be made one way and the exit to Millbrook Roundabout closed. This means any HGVs entering Third Avenue at Regents Park Junction has no way to exit or to turn around, so it is necessary to make the whole length of Third Avenue one way for the whole five weeks of ground preparation works. Once work in area 1 is complete this end of Third Avenue will be reopened two way.

Who is funding this work?

This work is being undertaken as part of enabling works funded throuhg the Millbrook Roundabout scheme provided by the DfT through the local area partnership.
