A novel sandwich composite footbridge is presented in the paper, as an example of practical application of laminated composites in civil engineering. The in situ static load tests of the footbridge before its acceptation for exploitation are shown and discussed. The results are compared with the corresponding ones from a numerical equivalent single layer model of the sandwich structure created within the framework of finite element method. The numerical solutions, are slightly higher than the measured in situ ones. Hence, it is concluded that the chosen method of structural analysis is efficient enough to recreate static behavior of the bridge and thus it is accepted for application in civil engineering.
