Fatigue and fracture events occurring in bridge structures built in the 1960s and 1970s are reviewed and methods used to repair damaged structures are outlined. One of the most important factors is the design lifetime of structures, usually considered to be more than 100 years. The means of guaranteeing the performance of structures throughout their lives with minimum cost is an engineering issue of increasing importance.
