Last update: May 2022

Latest updates

Traffic Management Update

Street lighting installation will be taking place at all three junctions during off peak hours from 9:30am to 4pm with stop and go boards in place to manage the traffic during May/June. No weekend working will take place.

  • Dibden roundabout;
  • Holbury and Hardley roundabouts.

Resurfacing at all three junctions have been completed.  

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

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.

Progress on this section of the scheme has experienced delay due in part to unexpected issues encountered with utilities. These issues are now being resolved and the works are anticipated to be completed later this month. The signs and barriers are for the lane closures necessary to enable this work to be undertaken safely.

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

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

The second phase of highway improvement works due to commence in June 2022 along the southern A326. Hampshire County Council is leading the delivery of the works and have appointed Milestone Infrastructure Services as their main contractor.

The location, details and estimated dates for the Phase 2 works are as follows:

June – October

  • Applemore Roundabout - widening of approaches and exit lanes. New toucan crossing and cycleway;
  • Blackfield Road / Church Lane / B3053 - new signalised junction and crossing facilities.

September – February

  • Heath Roundabout - widening of approaches and exit lanes. Improvement to east / west walking and cycling facilities.

During construction, temporary three-way traffic signals will be in operation at the junctions. The majority of the works will be delivered during standard working times Monday – Friday 7am to 6pm and Saturday 8am to 2pm. Later in the construction programme road surfacing will require overnight road closures. Further information on the dates and timings of the overnight road closures will be provided nearer the time.

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 Phase One 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.

Funding Arrangements

Total cost of the scheme: £8.1 million:

  • The Solent Local Enterprise Partnership has provided £5.7 million;
  • Fawley Waterside Limited has provided £2.4million;
