UK’s public spending watchdog to investigate Lower Thames Crossing project

The UK’s public spending watchdog has said it plans to investigate the Lower Thames Crossing, as campaigners voice concerns over the rising costs of one of the UK’s largest infrastructure projects.

The head of the National Audit Office (NAO) said he anticipated the agency would “examine and report” on the planned £11bn road tunnel between Kent and Essex, and that work to monitor the project had already started.
