Abstract: The Hammersmith Flyover is a 16 spans, 630 meters long concrete precast segmental bridge built in the 60’s. In 1999, detailed inspections have highlighted corrosion of existing prestressing tendons that could compromise the structural integrity of the structure. In 2006, acoustic monitoring was installed to assess the deterioration of the tendons. In December 2011, 6 months before the 2012 Olympic Games, additional analysis revealed an immediate structural risk. The flyover was closed to all traffic on 23rd December, causing extremely severe traffic disruptions. This paper describes a formidable surgery operation in two phases, to fully replace the existing post-tensioning system.
