An additional £174 million has been earmarked to cover rising costs on the planned Lower Thames Crossing, as concerns grow over the “spiralling” budget of one of the UK’s largest infrastructure projects.

The funding increase reflects continued pressure from inflation, construction costs and complex engineering requirements linked to the major road and tunnel development beneath the River Thames.

The project, designed to ease congestion at the Dartford Crossing and improve freight and commuter flows, has already undergone multiple revisions to its projected cost and timeline.

Transport officials said the additional allocation is intended to maintain progress while ensuring essential design and safety standards are met.

However, critics argue that repeated cost increases highlight broader issues in the delivery of large-scale infrastructure schemes in the UK.

Industry analysts say global supply chain disruptions, rising labour costs and regulatory complexity have contributed to budget escalation across major construction projects.

Local representatives have expressed concern about the financial burden on taxpayers, calling for greater transparency and tighter cost control measures.

Supporters of the scheme argue that the long-term economic benefits, including improved trade links and reduced congestion, justify the continued investment.

Transport experts say the Lower Thames Crossing remains a strategically important project for national logistics and regional connectivity.

Environmental groups, however, continue to raise concerns about the potential ecological impact of construction in sensitive areas around the Thames Estuary.
