EpsilonRebars with lengths of 60 m and 90 m were installed within two similar steel truss bridges, crossing the Noteć River in Poland. Nerve-Sensors were embedded inside the concrete slabs over their entire length. They were delivered on-site in coils and secured to the existing reinforcement along the main prestressing tendons. The designed and implemented nervous system of the structure is a perfect solution for both short-term load tests and long-tem monitoring.
