In promoting the CTRL Act through parliament, the Department for Transport (DfT) recognised the need to expand King's Cross St Pancras station. The station expansion is the responsibility of LUL as owner and operator and is directly funded by the DfT as part of the CTRL project.
London Underground has formed a joint project team with the DfT to ensure the project is delivered to requirements. SSL has been commissioned by LUL to deliver the project in its role as PPP infrastructure manager and will maintain and manage the station after completion. Hornagold & Hills provide project management support to SSL.
