This paper is dealing with the development of a structural health monitoring (SHM) system implemented on a composite footbridge during the regional project “Pays de la Loire” called DECID2. Due to the huge size of the composite bridge (20 m * 3 m), only its most critical areas are monitored as the assembling parts and the most solicited areas. To access the structural integrity of the footbridge, two complementary monitoring strategies were developed in this project: 

• a real-time acoustic emission monitoring system to detect fibre breaks;

• and a monitoring system using guided waves to evaluate the resin degradation.
