Lower Thames Crossing

The Lower Thames Crossing was developed to address severe congestion at the Dartford Crossing and to enhance transport resilience between Kent and Essex. As one of the UK’s most ambitious road infrastructure projects, it presented significant engineering and environmental challenges. The scheme had to navigate complex ground conditions, flood-risk areas, and protected habitats, all while meeting demanding regulatory, budgetary, and programme requirements. Coordinating multiple stakeholders and maintaining alignment with national infrastructure objectives added further complexity to the project’s early stages.

G&T is currently supporting the Lower Thames Crossing by delivering Procurement Services, Commercial Review & Assurance, Benchmarking Business Case Support, and Supply Chain & Supplier Relationship Management. We structured a procurement strategy tailored to engage suppliers early and competitively, ensuring alignment with low‑carbon objectives. Through detailed commercial assurance and benchmarking exercises, we are verifying value across the business case and reinforcing supplier relationships via proactive performance frameworks and engagement processes. These services provide the project team with a robust suite of commercial tools and insights, keeping cost, risk, and sustainability controls firmly in focus as the scheme progresses.

Although the Lower Thames Crossing remains in development, the interventions so far have already enhanced procurement transparency and strengthened commercial rigour. Clients and stakeholders benefit from data‑driven benchmarking, clarity in supplier performance, and assurance over value for money. As the project advances, G&T’s support continues to underpin strategic decision‑making, offering confidence in cost forecasting, supply chain capability, and alignment with low‑carbon delivery goals—all critical in achieving long‑term regional connectivity and sustainability ambitions.
