Summarised from 3 outlets · Updated 7 Oct, 06:15 · Archive

Night-time closures of the A350 near Chippenham are planned this month as work continues on the £32 million dualling project.

Drivers around Chippenham will face a series of night-time road closures this month as work continues on the £32 million project to complete the dualling of the A350 bypass. The closures form part of phases 4 and 5 of the A350 Chippenham Bypass scheme, which are intended to increase capacity, reduce congestion and improve journey-time reliability on one of Wiltshire's key north-south routes.

The A350 southbound between Badgers Roundabout and Bumpers Farm Roundabout will be completely closed overnight from Monday 5 October to Friday 9 October. The A350 northbound between Bumpers Farm and Badgers Roundabout will then be subject to full night-time closures from Monday 12 October to Thursday 15 October. A further closure of the A350 northbound between Cepen Park and Bumpers Farm Roundabout is planned for one night on Friday 16 October.

The work will complete the conversion of the remaining single-carriageway sections of the bypass to dual carriageway. The Government announced funding of £26.625 million for the scheme in its October 2021 spending review, with Wiltshire Council subsequently progressing the detailed design and business case. The main construction contract was awarded to MJ Church following further design, procurement and approval stages.

Full business case approval was received in January 2025, and main construction began in June 2025. The project is expected to be completed by December 2026.
