Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to the National Infrastructure and Service Transformation Authority's Annual Report 2024–25, published on 11 August 2025, for what reason no evaluation was completed for the Lower Thames Crossing.

The Lower Thames Crossing position can be found in the Tables section of the NISTA annual report which refers to the project post opening evaluation report (POPE). This report details the expected benefits once the scheme opens for traffic, how they will be measured and the actual ‘as measured’ benefits (3 years after opening) and produced as part of the Benefits Realisation and Evaluation Plan. Drafting of the POPE does not normally commence until the Full Business Case, which defines the expected benefits at the start of construction when they have reached full maturity and the scheme design is complete, has been approved.
