The Ouse Valley Viaduct (or the Balcombe Viaduct) carries the Brighton Main Line over the River Ouse in Sussex. It is located to the north of Haywards Heath and the south of Balcombe. Known for its ornate design, the structure has been described as "probably the most elegant viaduct in Britain. In July 1837, an Act of Parliament was passed which gave the London & Brighton Railway company assent to construct its proposed railway line between London and the south coast.[4] The route selected, which was surveyed by a team headed by Sir John Rennie, was fairly direct but had the downside of crossing over some relatively hilly terrain. As a consequence of a decision to limit gradients along the line to 1 in 264, the construction of a total of five tunnels and three viaducts, was necessary.
