This chapter presents the forensic investigations conducted after the collapse of the Sully-sur-Loire suspension bridge that occurred in 1985 in France. The failure mechanism concluded by the experts is the rupture of a cable-threaded tie in conjunction with a rupture of an element of the rigidity beam. The threaded ties had geometric defects, which were at the origin of the ruptures in service. These defects were either the threads themselves, or cracks due to fatigue, or corrosion phenomena. A decision-making process based on the determination of steel resilience was then launched to manage the other old suspension bridges in France during cold winters.
