The paper shows how the robustness concept, mainly developed and thought for the design of new structures, and the monitoring by suitable sensors based on fiber optics can also play a relevant role in the safety and management of existing bridges. A new approach of robustness more related to the long-term and service life of bridges is presented and its advantages in the decision-making process during the management of existing bridges are highlighted and afterwards applied on a real bridge. The continuous-in-space monitoring by the use of distributed optical fiber systems is also presented and the promising results and advantages regarding the flexural cracking assessment in concrete elements are shown.
