An international competition is about to start to find design ideas for restoration of a large network of railway arches in central London. Cross River Partnership and Spacia - the property arm of UK railway infrastructure operator Network Rail – hope to reduce the dissecting effect of the viaducts. CRP director Savas Sivetidis said that the viaducts are beautiful structures with a rich history dating back to the Victorian era. "Through the competition, we want to look at the part they can play in 21st century London, with ideas and designs worthy of a world-class city". The competition will be managed by the Royal Institute of British Architects and the brief will be available from next week. Entry is open to architects, engineers, landscape or urban designers.
