A326 (South) Fawley Waterside Junction Improvements

Last update: November 2021

Latest updates

Major highway improvement works commenced in June 2021, along the southern section of the A326 between Marchwood and Fawley. Hampshire County Council is leading the delivery of the works and has appointed Milestone Infrastructure Services as the main works contractor.

The work will be delivered in two phases, with arrangements and timings as follows:

Phase One
Night Time Highway Works and Road Closure – Main Road junction, Dibden

The works will commence 8pm on Monday 22nd November 2021, for a three week period, ending overnight on Friday 10th December. Working times will be Monday to Friday only, between 8pm and 6am. There will be no night time working over the weekends.

During the first two-week period, three-way temporary signals will be in operation at the Main Road junction. Following this, from Monday 6th December until Friday 10th December a full road closure will be in operation. This is necessary to enable the final element of works to be undertaken safely.

Please see the plan showing the location and extent of the closure, along with the proposed diversion route. A local signed diversion will be in place to redirect affected traffic during the closure. Access to residents and businesses will be maintained. Pedestrian access through the works will also be maintained.

Temporary Traffic Lights, Hardley Roundabout

Temporary, off peak only, traffic lights will be installed at at Hardley Roundabout from 26 July 2021 and are expected to be in place for 18 weeks. In addition, there will be traffic management in place around the junction to enable the works to be undertaken safely.

Temporary Road Closure and Traffic Signals, Holbury Roundabout

Long Copse will be closed to through traffic between its junction with Holbury Roundabout and Wentworth Grove. Access to properties will be maintained. Additionally, temporary traffic signals will be in place on the A326 Long Lane and B3053 Fawley Road arms of Holbury Roundabout.  The road closure will commence on 6 September 2021, and it is expected to be in place for 12 weeks.

The scheme working hours will be 7am to 6pm. Carriageway works will be limited to off-peak periods between 9am to 4pm, with an occasional need for night time works which will be minimised and notification provided in advance.

Milestone Infrastructure Services will be following the latest national guidelines on social distancing and all work will be carried out in-line with the Construction Leadership Council’s Site Operation Procedures based on Public Health England guidance.

Phase Two  

This second phase of works is being scheduled to commence later in 2021 for a period of approximately 12 months. More precise dates and arrangements will be advised nearer to the time.

This phase includes works to the following locations:

  • Applemore Roundabout (Sizer Way): widening of approaches and exit lanes, realignment of the National Cycle Network crossing of A326;
  • Blackfield Road / Church Lane / B3053: new signalised junction and crossing facilities;
  • A326 / Holbury Drove and Southbourne Avenue: capacity improvement and pedestrian crossing facilities;
  • Dibden Purlieu Roundabout: widening of approaches and exit lanes.
Scheme overview

Plans for improvements to seven junctions on the A326 and one on the B3053 between Main Road, Dibden and Church Lane, Fawley were recently awarded funding from the Solent Local Enterprise Partnership, with a contribution from the developer of Fawley Waterside.

The £8.1m scheme will increase capacity at the junctions that currently experience congestion and delays and will create a more resilient network that is better able to accommodate future growth in the area.

Please view ‘Meet the Contractor’ presentation for further details of the scheme and traffic management.

Scheme Background

The A326 (and the B3053 at its southern end) is the key road linking the communities of the Waterside Peninsula to the A35, the M27 and onward to Southampton and the wider area. It is a single carriageway road for most of its length, and various junctions experience existing peak period capacity issues and associated delays.

Analysis shows that with the addition of background growth, the capacity issues will increase and it is necessary to improve the junctions to address these issues and improve traffic flows.

The proposed A326 junction improvements will:

  • Contribute to the resilience of the existing highway network and relieve congestion on a keyroute;
  • Enable the development at Fawley Waterside to be brought forward whilst mitigating the potential transport impacts associated with it, (the proposed works are required to ensure that all necessary highway improvements works are delivered early ahead of the proposed Fawley Waterside housing development, in order to minimise potential transport impacts on the network);
  • Protect the rural environment of the New Forest by improving capacity on the A326 and helping to keep traffic on the main routes through the National Park during peak times.
Overall Objectives
  • Improve journey times, reduce congestion and increase capacity along the A326 between Dibden and Holbury;.
  • Improve network resilience and unlock economic growth by aiding adjacent nationally significant development areas along the corridor.
  • Ensure that all transport improvements take into account the sensitive environment and habitats of the New Forest and help to improve connectivity for the Waterside communities.
