Nine Arches Bridge, Demodara Sri Lanka

The Nine Arches Bridge  is a bridge in Sri Lanka. It is one of the best examples of British railway constructions when Ceylon was a colony of the British Empire. The construction of the bridge is generally attributed to a local Ceylonese builder, P. K. Appuhami, in consultation with British engineers.  The chief designer and project manager of the 'upcountry railway line of Ceylon' project was D. J. Wimalasurendra, a distinguished Ceylonese engineer and inventor. The designer of the viaduct was Harold Cuthbert Marwood of Railway Construction Department of Ceylon Government Railway.

It is located in Demodara, between Ella and Demodara railway stations. The surrounding area has seen a steady increase of tourism due to the bridge's architectural ingenuity and the profuse greenery in the nearby hillsides. It is often likened to the countryside through which the fictional Hogwarts express passes through in the Harry Potter world.

Popular rumours suggest that when construction work commenced on the bridge, the Great War began between the empires of Europe and the steel assigned for this site was reallocated to Britain's War related projects at the battlefront. As a result, the work came to a standstill, leading the locals build the bridge with stone bricks and cement, but without steel.
