HS2 Limited, the company delivering Britain’s high speed railway between London and Birmingham, has begun work on the first of a series of ‘green tunnels’, designed to carry the railway though environmentally sensitive regions. The cut-and-cover method revives a technique more usually employed in urban settings, but used here to enhance rural settings. When the projects are completed, they will be landscaped with locally native trees and shrubs to reestablish and benefit the surrounding countryside.
