St Denys Active Travel Zone (ATZ)

St Denys ATZ (001)


  • Where: St Denys
  • When: November 2020 for 12 months
  • What: An Active Travel Zone
  • Why: To create a better environment for everyone by identifying and making some small changes to the streets and roads that will improve walking and cycling for short journeys.
  • How: Funded as part of a Transforming Cities Fund awarded in March 2020

The Active Travel Zone project in St Denys has taken shape through collaboration with the residents of the neighbourhood. Southampton City Council has been working with the St Denys community over the past year to address concerns relating to air quality, levels of traffic, and safety for walking and cycling in the area that was raised in the Your St Denys Your Say survey in late 2019.

The St Denys Active Travel Zone is funded by money from the government’s Transforming Cities Fund.

You will find answers to common questions on our St Denys FAQs page.

Latest News

January 2022 update

Junction improvements on Aberdeen Road and Priory Road

Works to improve access to the Saltmead footpath on Priory Road, at the junction of Aberdeen Road, have been partly completed. These create a safer pedestrian environment and make the area more attractive. We will return in the coming months to add road surface treatment and plant the flower beds.

Kent and North Road modal filters

The trial modal filters on Kent Road and North Road have been in place for 14 months now. Monitoring of the modal filters has been carried out over an extended 12-month period, including traffic surveys both before and after their implementation. Data from these surveys shows that the modal filters on Kent Road and North Road have significantly reduced traffic on all roads in the St Denys area, with the exception of South Road which has seen a very minor increase. The biggest reduction has been on Priory Road (north), which has seen around 1,300 fewer vehicles a day using the route.

Traffic data also shows that AM and PM peak traffic flows on St Denys Road are at a similar level to those in January 2020 before the pandemic. This indicates that the measures have had little impact on journey times on the main road through the area.

Pedestrian and cycle counts have also been carried out as part of our monitoring and show positive early signs of an increase in walking and cycling, with increases recorded on most residential streets in the Active Travel Zone area.

Finally, we have analysed feedback received directly from residents, with many commenting that the changes have improved their quality of life; reduced air pollution; created safer, quieter roads; and enhanced the environment for people walking.

The key aims at the outset of the St Denys ATZ project were to improve the local area and make active travel safer, easier and more attractive. The modal filters on Kent Road and North Road have been shown to successfully support these and, with this in mind, we have taken the decision to make these measures permanent at both locations. 

We understand that not everyone has been in favour of the changes. However, we are confident that any current concerns will be far outweighed by the long-term benefits in terms of reduced traffic; improved air quality and road safety; and a better quality of life. We are committed to continuing our engagement with the local community and will be making ongoing improvements to enhance the schemes even further. As part of this, designs are being developed to replace the temporary bollards and planters with a permanent scheme which will make the spaces even more attractive to use on foot and by bike.

Dundee Road

Last year formal consultation took place on proposals that seek to improve road safety around St Denys Primary School. These proposals included a multifunctional shared space in front of the school with restricted vehicle access on the northern extents of Dundee Road at peak school drop-off and collection times.

We have reviewed the scheme following feedback received around the potential loss of on-street parking space; as there is no suitable way of amending the design to mitigate any loss of on-street parking, we will not be continuing with the proposals as originally outlined. We still plan to resurface sections of the footway, improve dropped kerbs and investigate widening the pavements at the entrance to Dundee Road.

Traffic counts show the primary school area is benefitting from the modal filter on North Road, with an increase in daily walking and cycling trips on Dundee Road since its installation. North Road has seen a traffic volume reduction of 39%, making the route to school safer from south St Denys.

South St Denys 20mph limit

To further improve safety, a 20mph limit is proposed across all streets in the area south of St Denys Road (a 20mph limit is already in place in north St Denys). This is supported by a recent Resident Request, which included a poll with 93% of respondents in favour of the speed restriction.

A change in speed limits will require a new Traffic Regulation Order (TRO). Residents on affected streets will be invited to respond to the formal TRO consultation when it is live.

St Denys Road corridor

Separate to the ATZ project, further changes are proposed for the wider St Denys Road corridor and include improvements to junctions and traffic signals, bus journey times and facilities for walking and cycling. Please look out for an upcoming survey which will seek your feedback on these proposals.

November 2021 update

Works have been scheduled to improve the gateway to Saltmead footpath on Priory Road, at the junction of Aberdeen Road.

This work involves footway improvements and a new kerb alignment build out which presents the opportunity for planting.  We shall return in the new year to complete the surface treatment works.

The works are due to take place from Monday 29 November 2021 for up to 3 weeks.  During this time the junction of Priory Road and Aberdeen Road will be closed to traffic and Saltmead footpath will not be accessible from Priory Road.  Pedestrians will still be able to use the junction, but not access Saltmead.  Vehicular access to Kent Road, Aberdeen Road and Priory Road will be via St Denys Road only.

The working hours of the site will be approximately 7:30am to 5:00pm. This is a noisy process and those properties close to the carriageway may experience some vibrations, together with flashing lights and reversing sirens.  We would like to take this opportunity to apologise in advance for any inconvenience or disruption these essential works may cause.

September 2021 Update

During our initial consultation on the St Denys ATZ, one of the most popular suggestions for how we could improve the area was to “ask drivers to turn off their engines at the railway crossing.” We are pleased to confirm that ‘no idling’ signs have now been installed at four locations close to the railway crossing in the St Denys area.

We would like to thank everybody that submitted their views as part of the Aberdeen Road and Priory Road/Dundee Road Traffic Regulation Order (TRO) consultations. We are in the process of reviewing schemes following the feedback we have received and the data we have collected.

We will require more information in order to make a final decision on these schemes and will conduct a second round of consultation when we have amended our plans. Residents will be notified when this consultation is live. In the meantime, please bear with us while we review the data we have and work to improve our proposals.

August 2021 Update

Trial modal filters have been in place on Kent Road and North Road for just over six months now.

Traffic surveys were carried out before and after their introduction and the data has shown that these measures have significantly reduced traffic on all roads in the area, except for South Road which has seen a very minor increase.

On Kent Road alone we have seen a reduction of around 1,000 vehicles per day. Surveys on St Denys Road show that the changes have had minimal impact on traffic along the main road.

Weighing the benefits and disadvantages, the decision has been made to extend the review period for another six months to November 2021. The planters will remain in place and the council will review this again in November. We will continue to work closely with the local community on the St Denys ATZ project.

Following feedback from residents it has been decided that the proposed modal filter at Priory Road North will not be delivered as part of the St Denys ATZ programme.

May Update

The continuous crossings along the St Denys Road junctions (Adelaide Road, Kent Road, Aberdeen Road, Priory Close, Stanley Road) were completed at the end of April 2021. During the work at Adelaide Road junction, we discovered the original tram lines that ran along St Denys Road so we worked around them. We are working towards the next phases that include buildouts by the school and Saltmead footpath as well as making a decision of the trial closures on Kent Road and North Road. We will keep you posted here.

Adelaide Road junction works 1 Adelaide Road drain and tram line Stanley Road junction Priory Close junction Aberdeen Road junction 

These works started January 2021 and ran over 14 weeks. Full details including a map showing the phasing can be seen on a separate page

January 2021 update

We have coordinated and programmed work between January and April to modify the junction mouths for five of the roads joining St Denys Road which form the second phase of the scheme. We are also coordinating with Gas Distribution Company SGN who are replacing a gas main along St Denys Road and Adelaide Road. Within this period we also plan to begin the trial closure of Priory Road North junction with St Denys Road but only after completing works at Kent Road junction.

November 2020 Update

Trial modal filters on Kent Road and North Road in St Denys were installed in the week beginning 16th November and will be in place while we seek feedback from the community.


Modal Filters - Experimental Trials

  • Modal filters, a feature used to limit through journeys by motor-traffic, will be implemented on Kent Road, North Road and Priory Road North.
  • The consultation period for Kent Road and North Road will run from November 2020 to May 2021.
  • The consultation period for Priory Road North will run from January 2021 to July 2021.
  • During the 6-month consultation period, monitoring will take place to establish the impact on St Denys of each modal filter.

Have your say:

Comments about the trial modal filters during the initial 6 month consultation period should be directed to

The permanent schemes will require consultation with residents before they can be implemented, so if you live in the vicinity of one of these, you will be contacted by letter with details of how and when to comment.

We have been engaging with residents in the Portswood and Swaythling area regarding ideas for schemes that could be introduced to improve transport and travel in the local area.
