Overview of the scheme

Transforming Cities Fund logo

Rudmore roundabout is a busy junction, used by local traffic, buses and a variety of vehicles accessing Portsmouth city centre, the Portsmouth International Port and cargo terminal, Portico, and the M275. The area is often congested at peak times, delaying local and Park & Ride bus services.

What is proposed and why

The current layout of Rudmore roundabout restricts the amount of traffic that can exit to the motorway. The proposals will allow bus priority and offers capacity improvements.

Our proposals will:

  • Widen the northbound access to the motorway increasing junction capacity
  • Extend the bus lane back to the roundabout exit onto M275
  • Change the layout of the roundabout to allow for two lanes from the A3 at Stamshaw Road and Kingston Crescent to travel to M275 northbound, improving the flow of traffic
  • Widen the road for vehicles exiting the roundabout southbound to make this a safer and easier route
  • Provide a safer exit from the roundabout and on to the existing off-road cycle lane for cyclists heading south

Have your say

All proposals are subject to consultation.  We asked for your views on what we’re proposing in a survey, but this closed on Sunday 5 September 2021. We’ll use feedback received to shape these plans to make them work for everyone.

You can now view the results of this consultation at our Your City, Your Say website.

We held some briefing sessions for these proposals in August 2021. Please contact us if you’d like to receive recordings of these briefing sessions for Rudmore Roundabout.

Next steps

The feedback we receive from our survey will help us to finalise designs, before undertaking a statutory 21-day consultation. We’ll update this page with further information and detailed designs as this scheme progresses to the next stage.

Although surveys are now closed on these schemes, we’d encourage you to sign up to our SEHRT community panel so that you can be informed about future developments for these sites, as well as future surveys about proposed developments in Portsmouth and across South East Hampshire.


There will soon be some lane closures on Rudmore Roundabout, and some temporary closures of the subway beneath it. This is so work can be done to prepare for further improvements to the roundabout later this year, including planting of new trees, shrubs and wildflowers.

Our contractor, Alun Griffiths, will carry out the works between 8:00pm and 6:00am from 11 April to 20 April 2022, but no works will take place on Good Friday (15 April) or Easter Monday (18 April). There will then be further work between 8:00pm and 6:00am from 9 May 2022 to 17 May 2022.

During this time, signs and traffic cones will be in place to help manage traffic around the area while some lanes around the roundabout and surrounding roads are closed. No roads will be fully closed and access to all surrounding roads will be maintained at all times. This will not affect any parking around the area.  A diversion will be in place when the subways underneath the roundabout are closed.

We need to close some lanes so that Alun Griffiths can safely remove some trees and trim some bushes on the roundabout. This will improve visibility of signs and hazards for people using it.

We’d like to reassure you that we are only removing trees that need to be removed to make these improvements, and plans are in place to replace them as well as add shrubs, wildflowers and other plants. Five trees on the northwest side will need to be removed to allow for two lanes exiting from the port onto the M275. A further two trees will need to be removed on the south side to move a cable underneath them.

As part of our programme, there are a number of plans to improve the area around the roundabout, including a small woodland area around the eastern side to compensate for any trees that are affected as part of these works. This will also make the environment greener and more pleasant for everyone travelling through this area.
