Overview of the scheme

We’re planning to update the road to make it easier for people to walk here and reduce bus congestion.

These proposals would provide benefits for active travel and public transport and support Portsmouth’s Local Transport Strategy and draft Local Cycling and Walking Infrastructure Plan (LCWIP).

Planned improvements

This scheme includes the southern end of Commercial Road and Isambard Brunel Road. This is a busy area, with lots of traffic and large numbers of people.

We are looking to improve the area for pedestrians and cyclists. Surrounding footpaths will also be improved to link with the Fratton to Portsmouth Guildhall walking route.

Once complete the following changes will be made:

  • Widen the road layout on Isambard Brunel Road to allow a two-way traffic flow, which will help to reduce congestion.
  • Add a new controlled pedestrian crossing on Isambard Brunel Road near Guildhall Square, this will help to make this area safer for pedestrians to cross.
  • Replace the mini roundabout with a crossroad traffic light junction. This will include controlled pedestrian crossings and will help to make this area safer for people to cross on foot.

City Centre South

During the period of works, to reduce congestion and prioritise safety, general traffic flow will be restricted through the Station Square junction and Isambard Brunel Road. This means the area will not be open to vehicles other than buses, taxis, private hire vehicles, vehicles accessing the train station and cyclists.

Access will remain for loading vehicles and we will continue to work alongside businesses to accommodate deliveries. The restrictions will stay in place throughout the duration of the project unless works are completed earlier. In addition to the traffic management for vehicles, safer diversion routes for pedestrians will also be signposted.

Most works will be completed during standard daytime working hours (7.30am – 5pm), however there will be occasional night works (between 8pm – 6am). Diversion routes will be clearly signed, with overnight closures advertised 14 days in advance through road signage.

Throughout these works we are committed to working alongside residents, businesses and transport operators to minimise disruption and communicate the changes in construction stages in a timely manner. If you would like to discuss options regarding delivery access during these works, please contact Martin Bungay by via email  or mobile 07827 081023.

An overview of the works is as follows:

Phase 1 – Station Square – Starting Monday 8 January

  • Works will start from Monday 8 of January with the site set up and works beginning on the footpaths.
  • From Monday 15 January Stanhope Road will be temporarily closed to general traffic flow. The restriction through to Station Square junction will be established for the duration of the works with diversion routes clearly signed. Temporary signals and traffic restrictions will be in place.
  • Pedestrian access around the Station Square roundabout will be maintained through a variety of temporary crossings. The zebra crossing on Station Street adjacent to the railway station will be removed and a temporary signalised crossing will be installed.

Phase 2 – Isambard Brunel – Starting Friday 12 January

  • On Friday 12 January works will start with a 24-hour closure over the weekend. The road will reopen at 6am Monday 15 January.
  • General traffic will be restricted between Station Square roundabout and the Dugald Drummond Street junction.
  • Two-way temporary traffic lights will be in place 24/7 to allow for works to be completed on one side of the road at a time, this work will continue for two months.

Our consultation was open from 17 December 2021 to 31 January 2022. The feedback we received helped us decide where to make specific improvements to this route, and how best to implement these changes. You can see the results of this consultation here.

A formal consultation for the Traffic Regulation Order (TRO) for the proposed loading bay started on Friday 23 June for 21 days (closing date for receipt of representations is Friday 14 July).
