South East LED roadside lighting upgrades
We’re cutting carbon emissions in the South East by switching to cleaner LED lights, making our motorways and A-roads greener and more energy efficient.
We'll retrofit most of the lighting in this region with LEDs by March 2027
This will help increase environmentally friendly LED lights across our network to at least 70%.

Here are details of our LED lighting work in the South East.
A21 Kipping's Cross and John's Cross
We’re surveying existing lighting on the A21 between Kipping’s Cross and John’s Cross to help us plan our upgrades.
We’ll use a mixture of overnight temporary traffic lights, lane and full closures, as detailed below. All work will be carried out between 8pm and 6am unless stated.
Please remember that closure details can change at short notice. For the most up-to-date information, please visit our daily closures page.
A27 Beddingham to Arundel surveys
We’re surveying existing lighting on the roundabouts on the A27 between Beddingham and Arundel to help us plan our upgrades.
We’ll be using a mixture of overnight temporary traffic lights, lane and full closures, as detailed below. All closures are between 8pm and 6am only.
Please remember that closure details can change at short notice. For the most up-to-date information, please visit our daily closures page.
A40 upgrade - 17 October 2025 to November 2026
We’ll use overnight (10pm - 6am) lane closures and road closures
We’ll start work near the Oxford Road junction moving in a clockwise direction.
We'll replace lighting around the inner ring of the roundabout first. Then we'll move on to the outer ring of the roundabout.
The Denham Roundabout carries traffic in both directions. When we need to close one side of the carriageway, we’ll divert traffic around the roundabout in the opposite direction.
Sometimes we may need to divert traffic away from the roundabout using local roads by signed diversion routes.
Please remember that closures can change at short notice. You can check the latest information on our daily closures page or find live travel information on our Traffic England site. Our travel alerts give details of live incidents on our network.
