Lighting replacement work to begin
As part of our effort to reduce carbon emissions from roadside lighting, we’ll be carrying out lighting upgrades to move from high pressure sodium lights (SON) to LED lights on the A47 between Shoreboat roundabout at Tilney All Saints and Pullover Roundabout near King’s Lynn.
LED lights are environmentally friendly and consume significantly less energy while providing the same amount of light.
They also have a longer lifespan and require less maintenance, resulting in fewer road closures for lighting repairs and, most importantly, safer roads for everyone.
We'll be working from Monday 17 November 2025 to Friday 20 March 2026 (8pm to 6am), weather permitting.
Preparation work
From Monday 17 November until Friday 19 December, we'll be working between Terrington St John up to the Pullover Roundabout, near King’s Lynn.
Initially we'll remove vegetation and prepare, ahead of starting the main work.
Closures and diversions
To work safely, we'll need to close the A47 in both directions between Terrington St John and the Pullover Roundabout, near King’s Lynn.

Project information
Overview
We’re replacing streetlights on the A47 between Wisbech and King’s Lynn.
As part of our effort to reduce carbon emissions from roadside lighting, we’re swapping our roadside lights from high pressure sodium lights to LED lights.
LED lights are environmentally friendly and consume significantly less energy while providing the same amount of light, so save electricity.
Depending on the type of bulbs we are replacing, we could reduce the energy we use for lighting by 65%.
We’ve already upgraded 73% of our streetlights in the East region.
Benefits
Road lighting makes up around half of our corporate carbon emissions.
LED lights are environmentally friendly and consume significantly less energy while providing the same amount of light, so save electricity.
They also have a longer lifespan and require less maintenance, resulting in fewer road closures for lighting repairs and, most importantly, safer roads for everyone.
LEDs have a lower failure rate than traditional lamps and require less maintenance during their whole life cycle.
And LED lights concentrate light where it's needed, meaning less light pollution.
