M3 junction 9 improvements

Closed 19 Feb 2018

Opened 9 Jan 2018

Results updated 24 Jul 2018

We consulted on this scheme in January and February 2018, where we received 854 responses. The majority of respondents were in favour of the proposed option (Option 14).

The results of the consultation are now available to view in our public consultation report which is available below, along with the Preferred Route Announcement leaflet which provides more detail about the scheme going forward.

To keep up to date with the scheme, you can sign up for updates on the scheme web page.



We are consulting on our proposal to provide free-flowing road links between the M3 and the A34, both northbound and southbound, with no need to enter the junction 9 roundabout to travel between the A34 and M3. The A34 southbound link will pass under the M3 with a 50mph speed limit.

These proposals would reduce congestion on the newly designed dumbbell road layout and make journey times more reliable, improve road safety and reduce air pollution.

We are keen to have your comments on the proposal; specifically on how the proposal could affect you, your organisation or those you represent. Find out more in the consultation brochure below.

The consultation runs for 6 weeks from Tuesday 9 January 2018 to Monday 19 February 2018.



The need for the scheme

Around 110,000 vehicles use junction 9 every day, a large roundabout across two bridges, which goes above the M3. The roundabout is partly give-way and partly controlled by traffic signals.

Due to the high volumes of traffic the M3 junction 9 roundabout cannot cope. Queuing traffic can often be found backing onto the main carriageway of the M3 northbound, resulting in safety concerns. Queuing traffic can also have a detrimental impact on environmentally sensitive areas such as the River Itchen and South Downs National Park.

The projected development of the Southampton container port is also anticipated to significantly increase heavy goods vehicle (HGV) traffic on the A34 and M3.
