DfT Appoints Senior Oversight Director for Lower Thames Crossing as Delivery Remains with National Highways

The Department for Transport (DfT) has appointed Kate Cohen, director of strategic roads and local projects, as the senior responsible owner (SRO) for the £10bn Lower Thames Crossing (LTC), providing high-level oversight while delivery continues under National Highways.

Cohen, who has previously worked as a project director at the former Infrastructure and Projects Authority, will act as a key liaison with the Treasury and support National Highways in managing the project within current financial constraints.

Nick Harris, chief executive of National Highways, told Highways:

“Contrary to some recent reports, the LTC remains with National Highways for delivery. The DfT’s appointment of Kate as SRO recognises the scale of the project and ensures focused oversight. We have collaborated closely with her across the portfolio, and her expertise in major projects makes her an excellent fit for this role.”

Industry sources highlighted that Cohen’s background equips her to provide effective client support and maintain constructive engagement with Treasury officials, particularly as the government seeks to manage costs amid budget pressures.

Earlier reports suggested that the DfT would take financial control of the scheme following criticism from Chancellor Rachel Reeves over delays and rising project costs, including environmental issues affecting local wildlife. Harris clarified that National Highways remains responsible for project delivery, while DfT oversight aims to ensure close coordination between departments.

The LTC has already achieved its final planning consent and received £590m for early preparatory works. Balfour Beatty was awarded a £1.2bn contract for construction of the connecting roads, and full project funding is being sought, including up to £2bn of private finance, potentially supported by toll revenues. Construction is expected to commence before the end of the decade.
