Traffic Management Update

Further night works and temporary road closures are required for the M27 Junction 9 and Parkway South Roundabout improvements. Night time working is necessary to avoid delays to the highway network and local signed diversions will be in place to redirect affected traffic.

The locations and duration of the temporary road closures are as follows: 

Between Parkway South Roundabout and a point approximately 150 metres south east of the roundabout;
From 5.00am on Saturday 4th December to 10.00pm on Sunday 5th December;
From 5.00am on Saturday 11th December to 10.00pm on Sunday 12th December;
The road will be closed in both directions to allow road widening and new carriageway construction to be undertaken.

Please note, these works are weather dependent and may need to be re-arranged at short notice. If required, any minor changes to the programme will be notified via the scheme webpage and Hampshire County Council’s social media channels.

Should you have any concerns whilst the works are being undertaken, please contact our works contractor Milestone Infrastructure on 0800 023 4169. May I apologise for any inconvenience caused, and please be assured that we will do all we can to keep any disruption to a minimum.

Hampshire County Council have appointed Milestone Infrastructure Services as the contractor for the major improvements to Junction 9 of the M27 and Parkway South Roundabout.

Milestone Infrastructure Services will be following national guidelines on social distancing and there is no reason to anticipate contact with members of the public. All work will be carried out in line with the Construction Leadership Council Site Operation Procedures based on Public Health England guidance.

The works commenced on 1 June 2020 to facilitate significant public utilities diversions that are subject to seasonal constraints and will include;

  • Earthworks for the embankment on the western side of Whiteley Way between M27 Junction 9 and Parkway South Roundabout;
  • Road crossings and ducting at Parkway South Roundabout.

The scope of future phases will depend on any ongoing social distancing measures that may remain in place and government guidance. Expected completion summer 2022.

Scheme overview

This £23 million project is jointly funded by Hampshire County Council and Highways England. The scheme will increase the capacity of the junctions and improve traffic flows by widening the roundabouts, adding additional lanes to the motorway slip roads and installing traffic lights at Parkway South roundabout (the first roundabout as you approach Whiteley). The scheme will reduce congestion and unlock economic development.

Existing high levels of congestion and delay at Junction 9 in peak periods, particularly on the off-slip roads, cause operational and safety issues on the M27 and cause a high level of frustration for those caught up in it. This combined with development of 3,500 extra homes in the north of Whiteley means that an improvement scheme is much needed so that people can access the shopping centre, cinema, restaurants, Solent Business Park and the further afield Segensworth Business Park, without delay.

The County Council will be providing an additional traffic lane on both M27 Junction 9 motorway off-slip roads; on the westbound on-slip road and on the Whiteley Way approach. The existing short left-turn lane on Whiteley Way will also be lengthened and additional lanes will be provided on the northern and southern sections of the roundabout. At Parkway South roundabout a new larger fully signal-controlled roundabout will be provided, with additional lanes on all approaches, on the Parkway exit road and on the roundabout itself.

This scheme will be critical in ensuring that the £14 million being invested by the Solent Local Enterprise Partnership to widen Whiteley Way and the £150 million being invested by Highways England in the M27 Smart Motorway Scheme, will be a success. Each scheme will compliment each other and transform the way traffic flows in this area.

Exhibition plans update

Due to current guidance regarding COVID-19 and social distancing it is no longer possible to hold a public exhibition to coincide with the start of works. You can access an overview of the scheme and plans setting out the works to be undertaken during phase 1 commencing on Monday 1st June 2020.

The programme for subsequent phases of work is currently being revised due to the impact of COVID-19. Further information regarding construction phasing and traffic management for future phases will be updated on the scheme webpage when confirmed.
