A421 Wootton to Marston Moretaine noise barrier and streetlight work
We’re replacing 1,500 metres (1 mile) of noise barrier on the A421 between Wootton and Marston Moretaine. This will reduce road noise and glare from local network roads. We’re also replacing the existing lights with energy-efficient LED lighting to reduce our carbon emissions and save the taxpayer money by lowering electricity costs.

The final phase of work
The final section of this work is the longer, westbound stretch of the A421. We expect to begin this work in May.
We plan to complete this scheme in August 2024.
To work safely, we'll need to close the motorway and slip roads at various locations. Please remember that closure details can change at short notice. For the most up-to-date information on dates, times and locations, check our daily closures page.
Diversion routes will be clearly signposted. Please don't follow your satnav during any closure and check your journey before you travel.

Project information
Overview
We’ll replace all sections of noise barrier at Lower Shelton, Wootton and Marston Moretaine with steel posts and composite panels.
The new fence will remove glare from local roads, reduce road noise and the view of traffic from nearby housing.
We’re also replacing the existing lights with energy-efficient LED lighting to reduce our carbon emissions and save the taxpayer money by lowering electricity costs.
Benefits
The composite panels of the new barrier will be made from recycled waste material, reducing plastics going to landfill and noise along the A421.
The new barrier will have a life span of 30 years or more. It will also reduce the risk of glare from the A421 onto local roads.
