M27 Junction 9 and Parkway South roundabout improvements, Whiteley

Last update: November 2018

Scheme overview

Hampshire County Council will be undertaking a £20 million improvement scheme to widen Junction 9 of the M27 as well as 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.
