The design of the HS2 railway, including associated features such as the Addison Road Bridge, is a matter for HS2 Ltd, the company charged with the project’s delivery, and its contractors. The design of the Addison Road bridge was developed by the main works contractor to Scheme Design stage during 2019. This was shared with the HS2 project team at Buckinghamshire County Council in July 2019 and feedback was received from them in October 2019. The design for the highway is expected to be finalised in May 2020, where further review and pre-application discussions are planned with the local authority. The Department is not directly involved in the detail of this process, but was involved in establishing the overall framework and continues to monitor it.
