HS2 has revealed the first images of the longest of three ‘green tunnels’ that will be built across Buckinghamshire and Northamptonshire to help blend the new high-speed rail line into the landscape and reduce disruption for residents.
The one-and-a half-mile long Greatworth tunnel will be built in a factory in Derbyshire before being shipped to site and assembled over the railway line as it passes the village.
It will then be covered with earth and landscaped to fit into the surrounding countryside.
Applying lessons from the construction of the latest French high speed lines, an ‘off site’ modular approach was developed by HS2’s main works contractor, EKFB - a team made up of Eiffage, Kier, Ferrovial Construction and BAM Nuttall.
HS2 Ltd’s Project Client Rohan Perin, said: “The Greatworth green tunnel is a great example of what we’re doing to blend the new railway into the landscape and protect communities living close to the line.
“By adopting an ‘off site’ approach to manufacturing, we’re also cutting embedded carbon from the design, improving efficiency, safety and making the whole construction process less disruptive for the community.”
