For instance, the bridge lacks proper deep foundations, resting on R.C. caisson foundations sunk by self-weight, and it is thus potentially subject to scour. Furthermore, the bridge features half-joints and suspended spans, which introduce a risk of local, sudden brittle failure. On the other hand, the Amedeo VIII bridge has been constantly maintained with due diligence, including periodic surveys, a large campaign of destructive and non-destructive tests in 2000, and extensive structural interventions in the last decade, involving the installation of external post-tensioned tendons in 2011. As part of this broader initiative to assess and preserve ageing critical infrastructure, the Amedeo VIII Bridge is currently being instrumented with a multi-sensor system for Structural Health Monitoring (SHM). More specifically, this system integrates physically-attached instrumentation (including inclinometers and strain gauges) with advanced remote- and proximal-sensing technologies (specifically, satellite-based InSAR and photomonitoring). Thus, this contribution briefly presents the tailored SHM strategy designed to ensure long-term operational safety.
