Traffic Management Update

Monday 15 April to Friday 19 April 2024

Topsoiling and re-seeding of grassed verges will be taking place at various locations on the Brighton Hill roundabout central island and within verges on the approaches. There will be no road restrictions and all footways and cycle lanes will be accessible to all.

Brighton Hill Roundabout in Basingstoke is now fully open after a £20 million improvement scheme delivered by Hampshire County Council which will reduce congestion and make journey times more reliable for road users.

Please see the completion presentation and watch the video showcasing this scheme.

The A30 roundabout has been designed to reduce congestion by widening the road to increase traffic capacity whilst new traffic signals aim to manage traffic flow more efficiently. Toucan crossings have also been installed to enable people to cross safely. Tree and vegetation replanting has been designed to maximise species diversity, provide plants for pollinators and look attractive.

The scheme has also delivered a new three metre wide fully segregated walking and cycling route alongside the existing footway in Brighton Way, between the Brighton Hill Roundabout and Sullivan Road.

The County Council appointed Milestone Infrastructure to construct the roundabout improvements. The scheme has been funded with £11.6 million from the EM3 Local Enterprise Partnership’s Local Growth Fund and £7.65 million from Hampshire County Council.
Stephen Martin, Managing Director of Enterprise M3 LEP, said: “We are delighted to have played a part in improving Brighton Hill Roundabout and are especially pleased the work has been completed in time for the extra busy Christmas period. This should significantly ease traffic congestion along this key access route that links several residential, retail and business areas with the town centre. While we appreciate there has been disruption to local residents, we are sure the improvements will bring huge benefits to those living and working in the immediate area, as well as across the wider Basingstoke community.”

Brighton Hill Roundabout is a key junction on Basingstoke’s A30 South West corridor - a critical strategic route between the M3 Junction 7, the Ringway and adjoining links to Basingstoke’s retail and commercial centre.

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.
