According to National Highways, the new images showcase how the project is being shaped by putting low-carbon construction and nature "at its heart".

It is aiming for the Lower Thames Crossing to be "Britain's greenest road", with six times more green space than road, one million new trees and seven green bridges, designed to facilitate wildlife movement across roadways.

Most of the route will be in a tunnel or hidden behind landscaped embankments and mounds, it said.

The new images will be showcased at a series of community events across Kent and Essex, starting on Wednesday.
