stonework falling away from the balustrades and parapets. Starting in March 1996, the viaduct underwent a £6.5 million renovation overseen by the national rail infrastructure company Railtrack and partially funded by grants from West Sussex County Council, Railway Heritage Trust and English Heritage. Harder-wearing limestone was imported from Bordeaux to ensure the closest match with the existing Caen stone in the balustrades and pavilions. Some of the piers had to be reconstructed because of failures in the Victorian brickwork. The new bricks were handmade in a variety of sizes to suit the existing brickwork and set in sand, cement, and lime mortar; stainless steel anchoring was used to firmly fix the new stone to the old stonework. Throughout the work, one of the lines always remained open while restoration activity was being carried out on the other side of the viaduct. The project, which took more than three years, was completed in September 1999.
