Quicker bus journeys and safer walking and cycling for Portsmouth in 2024

Schemes designed to improve bus journeys, walking and cycling across Portsmouth start work in City Centre South this week with planned completion in May 2024.

These works are part of the plans to improve bus travel and active travel (walking and cycling) across the city as part of the South East Hampshire Rapid Transit (SEHRT) project.

The following improvements will be introduced to City Centre South:

  • The road layout will be widened on Isambard Brunel Road to allow a two-way traffic flow, which will help to reduce congestion.
  • A new controlled pedestrian crossing will be installed on Isambard Brunel Road near Guildhall Square which will help to make this area safer for pedestrians to cross.
  • The mini roundabout will be replaced 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.

Cllr Gerald Vernon-Jackson, Cabinet Member for Traffic and Transportation at Portsmouth City Council said:

“2024 is going to be an exciting year for Portsmouth as multiple infrastructure schemes are coming to fruition to promote more sustainable transport options. The changes underway to City Centre South will improve the way people travel in this space, benefitting all users, easing congestion and improving air quality.

“As more people are choosing to walk and cycle in the city, it is important that we continue to invest in the infrastructure that keeps them safe. I look forward to seeing more people choosing to travel by bus, bike and on foot once the works are completed.”

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

Using the park and ride is an ideal option when you are planning on traveling into the city by car, with journeys taking less than 10 minutes when travelling to the city centre. Tickets can be purchased from the machine at the main building or by ordering a smart card through the website. Visit to find out more.

The restrictions will stay in place throughout the construction phase unless works are completed earlier. Part of the works will be carried out at night, however most works will be completed during standard daytime working hours (7.30am – 5pm).

All City Centre South bus routes will be running as usual, however at times some bus stops will be relocated. Please check details with bus operators. Safer diversion routes for pedestrians will also be signposted and access to Portsmouth and Southsea Railway Station will be maintained.

These works link to the improvements to bus journeys, walking and cycling on Lake Road and Unicorn Road junction which started in September, and the upcoming works starting on Charlotte Street later this month.

Once complete, all of these improvements under the SEHRT project will work together to make it easier for people to get to and from Portsmouth and surrounding areas by bus, bike and on foot. This will make it simpler for people to choose healthier, more active ways to travel whilst helping to reduce congestion.

Since securing £56m in funding from the government’s Transforming Cities Fund (TCF) in 2020, Portsmouth City Council, Isle of Wight Council and Hampshire County Council have been working on improving bus infrastructure, walking, and cycling as part of the South East Hampshire Rapid Transit (SEHRT) programme.
