How to Build a Railway is a twelve-part podcast series exploring the story behind the construction of the UK’s new high speed rail line.

This episode of the HS2 podcast series goes back above ground to explore the design and construction of bridges, with a specific focus on HS2’s iconic Colne Valley Viaduct.

Good infrastructure will impact minimally on the surrounding environment. For some stretches of the HS2 route, the diverse landscape and ground conditions are not suitable for tunnels. Where elevated sections of the line are needed – like over lakes and waterways – it brings opportunity for the engineers and architects working on the project to construct a modern and complementary design for the railway, reflective of its natural surroundings.
