A350 Chippenham Bypass Improvements (Phase 4 and 5)

Latest News

Advanced Works

Advanced works have now started on the A350 Phase 4-5 dualling site.  These works focus on vegetation clearance before the start of the bird nesting season, and some initial earth moving work.  Undertaking these advanced works now helps avoid delays to the main scheme which is anticipated to start later this year.

Contract Award

In December following a robust procurement process, Wiltshire Council announced its intention to award the contract for the final phases of dualling the A350 at Chippenham to local company MJ Church.

The main work is expected to begin in spring 2024 and end in autumn 2025, subject to the approval of the Full Business Case by the Department for Transport.
