Hampshire County Council contractor Milestone Infrastructure Services. A meet the contractor event was held in February 2022, please view the presentation.

The major improvements to Brighton Hill Roundabout commenced on 24 January 2022.  Works are due for completion winter 2023.

The working hours are 7.30am to 6pm Monday to Friday and 8am to 1pm on Saturday.

To facilitate the works, traffic management will be required to provide safe working space for the workforce. During peak hours, 6.30am - 9.30am and 4pm - 6.30pm the same number of lanes will be maintained on the A30 through the Brighton Hill Roundabout and on the other entries (Western Way/The Harrow Way/Brighton Way/Winchester Rd), these will be reduced to single lanes.

Off peak, the contractor may require additional road space and reduce traffic to single lanes on all arms of the roundabout. Pedestrian diversions will be in place for the duration of the works and our safer routes to schools’ team are working with the schools to provide support. Please allow more time for your journey.

The site compound is set up on the site of the former Camrose football ground within the existing car park.  Access to the former football ground will remain open for ongoing maintenance by the landowner. The site is leased to the contractor by Basingstoke Town Limited. Hampshire County Council are not party to the lease.

Scheme overview

Brighton Hill roundabout forms a key junction on Basingstoke’s A30 South West corridor. This corridor provides a critical strategic route between the M3 Junction 7, the Ringway and adjoining links to Basingstoke’s retail and commercial centre. The route is a focus for future growth including 2,000 homes on strategic housing sites adjoining the A30. In addition, the route will also need to accommodate traffic from the nearby Manydown development to west of Basingstoke, where a further 3,500 homes are planned. Currently congestion at the Brighton Hill roundabout regularly results in extensive queues and journey time delays. Without improvements, congestion will worsen as traffic levels increase from the planned development in the area.

The Brighton Hill improvement scheme aims to support growth, reduce journey times and create an enhanced and safer environment for cyclists and pedestrians. The scheme will widen and signalise Brighton Hill roundabout and add additional capacity to its main arms.

Good infrastructure is vital to Hampshire’s continued economic prosperity. These improvements aim to make daily travel easier for residents and commuters and will help to ease congestion, enhance safety and increase local opportunities to walk and cycle. Main works for the scheme are scheduled to begin in Autumn 2021 for an approximate two-year period.


This scheme forms one part of a multi-million pound transport investment in the Basingstoke area which also includes improvements to: 

  • A340 Aldermaston Road;
  • A33 Popley Way;
  • A339 Ringway Junction;
  • A33 Crockford Roundabout and Binfields Roundabout;
  • A33 Thornhill Way;
  • A340 Thornycroft roundabout.

The £19.3m scheme is being funded by:

  • £11.65m - EM3 Local Enterprise Partnership;
  • £7.65m - Hampshire County Council.

Hampshire County Council has secured £3.28 million from a successful bid to the Government’s Active Travel Fund. The funding will be used to provide a range of measures throughout Hampshire to create better spaces for walking and cycling in local communities.

A new three metre wide cycle track will be built alongside the existing footway in Brighton Way. For more information please visit the scheme web page.
