Bridge monitoring is becoming an essential practice in Europe, especially for old structures interacting with unstable slopes whose design is not adequately known and where maintenance is typically not performed over a regular basis.
Modern technologies, such as wireless dataloggers connected to geotechnical sensors (e.g. bar extensometers, clinometers, optical distometers, etc.) allow to monitor in near real time the stability of those structures at affordable costs, providing warnings by email or text message in case of anomalous accelerations.
In the picture below some examples from recent installations carried out by Geoapp in Italy by using Winet wireless dataloggers.
