A350 Chippenham Bypass Improvements (Phase 4 and 5)

Latest News

Full Business Case Approval

The Department for Transport have now approved the Full Business Case for the A350 Chippenham Bypass Phases 4 & 5. 

Local residents will benefit from reduced traffic on more local routes as well as better road safety and better access to jobs in the area. Businesses are expected to save time and money, as goods can travel more freely with improved access to a key part of the UK's road freight network.

Work is expected to start in Spring 2025 and will be complete towards the end of 2026. 

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 2025 and end towards the end of 2026.
