Lighting replacement work
We'll be replacing the lights at the Station Road entry and exit slip roads, including the flyover bridges.
LED lights are better for the environment and use far less energy to produce the same amount of light.
They also last longer and require less maintenance, meaning fewer road closures to fix lighting in the future and more importantly, safer roads for everyone.
We'll work over six weeks, starting from Monday 2 February until the end of March 2026. We’ll be working overnight from 8pm to 6am, weather permitting.
