Our surveys have revealed large numbers of dead or dying Ash trees. These are a potential safety risk to people on or near our road network.

We need to remove or make safe ash trees identified as needing urgent action.

We'll need a combination of overnight lane and carriageway closures while we work. Our next work (s) will be:

Monday 3 November for approximately 5 months

The A303 will be closed in both directions overnight (8pm-6am) between Devonshire Inn and Southfields roundabout on 18 December 2025.

This is to complete three schemes which include:

• replacing road studs
• retexturing the surfacing for better skid resistance

Although the closure covers a significant stretch, doing two schemes in one night avoids two separate closures and helps minimise disruption for local communities.

Diversion: 

Signed diversion routes by Chard will be in place during the closure.

Limited local access to the A303 will be possible between Stopgate Cross and Broadway Hill junction.

The work will take place weeknights only from Tuesday 16 September to February 2026 (8pm to 6am).

Dates may change at short notice due to poor weather conditions or operational reasons. If we’re unable to complete our work as planned, we may need to continue beyond the dates stated above. 

Well-signed diversions will be in place to help you plan alternative routes.

We know roadworks can be frustrating, but this work is vital to maintain safety standards on this busy route. By working overnight on weeknights, we're minimising disruption to your journeys.
