The UK's Largest Road Tunnel Project Receives £590 Million

The government has approved a £590 million project to construct the biggest road tunnel in the United Kingdom.
The estimated cost of building the Lower Thames Crossing, which would connect Gravesend, Kent, and Tilbury, Essex, is £10 billion.
The 14.5-mile (23-kilometre) route's plans were approved in March, following a 16-year process that has already cost £1.2 billion. “Smoother, less congested passage of vital goods from Europe to our regions” is what Chancellor Rachel Reeves had to say about the crossing.
Lower Thames Crossing: An Essential Project
On Monday, it was revealed as a component of a £1 billion package to upgrade England's transport system. The government declared that the Lower Thames Crossing was a “national priority” and searched for private funding to build it.
National Highways anticipated a 20% decrease in traffic at the Dartford Crossing as a result of the road.
Notably, it was projected that construction would start in 2026 and that the building would open in 2032.
“This is a turning point for our national infrastructure, and we're backing it with funding to support thousands of jobs and connect communities,” Reeves stated.
Moreover, Transport Secretary Heidi Alexander emphasised the importance of this project in enhancing the resilience of a crucial freight route and ensuring long-term trade with Europe. However, Treasury minister Emma Reynolds struggled to answer questions about the project on a national radio programme.
Meanwhile, LBC's Nick Ferrari mistakenly called the existing crossing Dartmouth, not Dartford, and couldn't recall the landing zone when asked about the new crossing location.
Reynolds stated that the cost of the project will be significant, with National Highways estimating it to be between £9.2 billion and £10.2 billion, depending on the chosen funding model.

The New Route's Salient Aspects
The road will connect the A2 and M2 in Kent with the A13 and M25 in Thurrock, extending from Tilbury to Gravesend. About 2.6 miles (4.2 km) of the route will be underground, with northbound and southbound tunnels running beneath the Thames.
Significantly, Logistics UK, the transport and logistics sector's representative, welcomed the funding announcement for the Lower Thames Crossing project. The move is seen as crucial for the government's growth agenda and aims to ensure efficient logistics with minimal delays, following a decade of hold-ups at the vital interchange, according to policy director Kevin Green.
Besides, the government must devise a comprehensive plan for securing the necessary funding for the project, ensuring efficient delivery for the industry and benefiting the economy, as members deserve to be supported.
Nonetheless, activists have expressed worries about how the projects may affect old woodland.
“Absolute madness” is how Chris Todd, the director of Transport Action Network, described the decision earlier.
He further stated, “The only way that the government can afford this white elephant would be to take money from all the other nations and regions in the UK.”
