HS2 has released new footage showing the progress on Britain’s longest railway bridge near Buckinghamshire.
To celebrate the new year, HS2 Ltd revealed how construction for the country’s longest railway bridge is progressing at the border of Buckinghamshire and Hillingdon.
The River Colne Viaduct will stretch for more than two miles when completed, connecting HS2’s London and Chiltern tunnels, with trains travelling at up to 200 miles per hour.

For more than a year, the giant 700 tonne bridge building machines and their teams have worked non-stop to create the bridge over the lakes and waterways in the Colne Valley Park near Denham.
The bridge is made using deck segments each weighing 140 tonnes, which is more than the average weight of the world’s largest animal, the blue whale.
The Minister for HS2 and Rail Huw Merriman walked on the first stretch of the viaduct last January to appreciate the “extraordinary feat of engineering and architecture.”
