About this source

What it is

The Wharncliffe Viaduct is a brick railway viaduct near Hanwell, west London, designed by Isambard Kingdom Brunel and built in 1836–1837. It was the first major structure completed on the Great Western Railway and remains in use today, owned by Network Rail.

Why it matters

As Brunel's first completed large-scale structure, the viaduct marks the beginning of his career building the Great Western Railway, a project that would define his reputation as an engineer. Its survival in daily use shows the durability of his early designs.

Look closer

  • What does the arched brick construction suggest about building methods and materials available at the time?
  • Why might a railway company want its first major structure to look impressive as well as functional?
  • How does this early project compare to later, more ambitious Brunel structures?
