Landmark Funding Paves the Way for UK's Largest Road Tunnel

The UK's ambition to significantly upgrade its transport infrastructure has taken a major leap forward with a £590 million government grant for the Lower Thames Crossing, set to become the nation's largest road tunnel. This substantial investment is part of a broader £1 billion package aimed at improving transport networks across England.

The project, which received planning approval in March after a 16-year process, will create a vital new route linking Tilbury in Essex and Gravesend in Kent. Spanning 14.5 miles (23km), the Lower Thames Crossing is designed to ease congestion and enhance the flow of goods, particularly those arriving from Europe. A significant portion of the route, approximately 2.6 miles (4.2km), will run underground beneath the Thames, with parallel northbound and southbound tunnels.

National Highways anticipates that the new crossing will reduce traffic at the existing Dartford Crossing by 20%, a crucial improvement for one of the UK's busiest bottlenecks. Construction is slated to begin in 2026, with an expected opening by 2032.

This development is seen as a pivotal moment for national infrastructure. The government has highlighted the Lower Thames Crossing as a "national priority" and is actively seeking private finance to support the estimated £9.2 billion to £10.2 billion cost.

The transport and logistics sector has widely welcomed the funding announcement. The industry recognizes the critical role of efficient logistics and minimal delays in supporting economic growth. This initial funding marks a significant step towards alleviating long-standing holdups at this crucial interchange, providing a more reliable and efficient route for freight and commuters alike.
