Next stage of upgrade to A340 Thornycroft Roundabout in Basingstoke

As part of Hampshire County Council’s ongoing commitment to improve congestion for businesses and residents in Basingstoke, the next stage of a major improvement scheme at the Thornycroft roundabout will begin on 5 October with six weeks of scheduled night works

Sep 21 2020

Working hours will be 8 pm to 5:30 am Monday to Friday from Monday 5 October to minimise disruption for those going to work, school and college in the area.

Councillor Rob Humby, Deputy Leader of Hampshire County Council and Executive Member for Economy, Transport and Environment, said: “This project aims to reduce journey times and improve traffic flows on the A340 corridor. To manage traffic effectively, avoid delays, and ensure the safety of our workforce, it will be necessary to close sections of the roundabout in phases at night, meaning a short diversion will be required and will be fully signposted. Pedestrians and cyclists are advised to continue using the existing subways and footbridge to cross the main roads and not approach the works area. Temporary signage will be in place for guidance. 
“Whilst every effort will be made to keep disruption to a minimum, the nature of the works means that some disturbance is to be expected, for which I apologise in advance. We are asking people to plan their journeys.”

The £9.5 million Thornycroft roundabout improvement scheme is part of a multi-million-pound package of transport improvements being delivered by Hampshire County Council in the Basingstoke area, which also include improvements to Brighton Hill Roundabout, Aldermaston Road, Winchester Road Roundabout, the A33 Popley Way, Crockford Roundabout, Ringway Roundabout, Binfields Roundabout and Thornhill Way. 

By increasing resources on the scheme, the County Council’s contractor, Mildren Construction Ltd, has manged to minimise the impact of Covid-19 works suspension  and the works are on course to be completed in January 2021.

These works are being designed and delivered by Hampshire County Council with funding support from the EM3 Local Enterprise Partnership.
