A120 Horsley Cross to Wix concrete road reconstruction

We're reconstructing the A120 between Horsley Cross and Wix in both directions, with work starting during 2024/25. Reconstruction involves completely removing the concrete road surface and some of the foundations, before rebuilding the road and resurfacing it with asphalt. We'll also be clearing drains, repainting road markings, inserting new reflective road studs (cat’s eyes) and replacing damaged safety barriers. This will improve safety, create a smoother quieter journey and extend the life of the road to make it fit for the future.
