A 500-tonne transformer load linked to the Hornsea Three offshore wind farm construction will close the A47 in Norfolk on October 29, 2026. This is the last of nine transformers being transported to the Orsted Onshore Converter Station in Swardeston, affecting local traffic significantly. The load will be escorted by Norfolk Police and will travel at a maximum speed of 10 mph, leading to road closures throughout the day. The Hornsea Three project, expected to be the largest offshore wind farm globally, will generate 2.9 gigawatts of energy, enough to power over three million homes. The project received approval in December 2021 and is set for completion in 2027. Previous transport of transformers has been scheduled on Sundays to minimize traffic disruption.
