Scheme overview

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

This £23 million project was jointly funded by Hampshire County Council and Highways England. The scheme increases the capacity of the junctions and improves the traffic flows by the widened roundabouts, the additional lanes to the motorway slip roads and installation of the traffic lights at Parkway South roundabout (the first roundabout as you approach Whiteley).

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 has provided 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 has been lengthened and additional lanes have been provided on the northern and southern sections of the roundabout. At Parkway South roundabout, there is a new larger fully signal-controlled roundabout, with the additional lanes on all approaches, on Parkway exit road and on the roundabout itself.

This £14 million scheme that has been invested by the Solent Local Enterprise Partnership for the widening of 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.

Funding Arrangements

Funding for this scheme is being provided by Highways England and local developer contributions, broken down as follows:

  • £13.8 million from Highways England
  • £9.2 million Hampshire County Council
