The Lower Thames Crossing includes 14.3 miles of new road and Britain’s longest road tunnelDIGGING DEEP Jaw-dropping £9BILLION plan for UK’s longest motorway tunnel that will cut journey times in half is unveiled in picsJAW-dropping new images showcasing the plans for the upcoming Lower Thames Crossing have been released. The UK government is planning to build the huge, motorway-style tunnel in a project that would cost some £9 billion. First planned back in 2009, the Lower Thames Crossing would reportedly see 13 million vehicles redirected away from the heavily congested Dartford Crossing. The building of the Lower Thames Crossing would also have a positive impact on motorists; journey times at the Dartford Crossing would likely improve by around 30% and increase to 46% between Kent and Essex. The use of gantries will reduce steel and concrete to help cut carbon, while maintaining strength and durability, helping build a more sustainable Lower Thames Crossing.
