Imberhorne Viaduct

Imberhorne Viaduct is a Grade II listed railway viaduct located in East Grinstead, West Sussex, South-East England. Closed in 1958, the structure was brought back into use as part of the preserved Bluebell Railway heritage line in 2013, allowing trains to continue to East Grinstead railway station.

Built to span the lands of Imberhorne Farm, it was designed and engineered by Frederick Banister, then Chief Engineer for the London, Brighton and South Coast Railway. Built as part of the Lewes and East Grinstead Railway and built to allow double-track operations, it is 700 feet in length and spanning the valley at a maximum height of 90 feet . Construction started in 1880, with ten brick arches each with a span of 60 feet reaching a maximum height of 70 feet , each having no fewer than eight rings. The parapets have five panels above each arch, and there are brick string courses below. A feature of the viaduct is that the imposts are of stone on the face of the piers, but brick within the arches.
