en.Wedoany.com Reported - The Metropolitan City of Florence, Italy, has adopted an intelligent monitoring system based on wireless sensors developed by Milan-based startup Displaid on five strategic bridges of its road network, becoming one of the first entities nationwide to introduce a large-scale bridge monitoring model to optimize infrastructure management. The project completed the installation of 168 sensors within four working days, without interrupting traffic throughout the process, maintaining continuous vehicle flow during all equipment installation phases.
The Displaid system adopts a condition-based approach, detecting structural displacement and vibration in real time. The collected information is processed by specific algorithms to quickly identify any potential issues, supporting technical personnel in making decisions regarding necessary interventions. This bridge monitoring project shifts maintenance from a reactive to a predictive approach.
Among the various infrastructures involved in the bridge monitoring, the Montelupo-Capraia Bridge on Provincial Road SP 106 is a key focus. The structural renovation execution project for this bridge is currently being developed, with an estimated investment of approximately 7 million euros and a contract deadline set for 2027. While awaiting the start of construction work, continuous bridge monitoring ensures maximum operational safety and allows for timely intervention in case of anomalies. Traffic management in this area is closely linked to the new Arno River bridge built by ANAS in the Fibbiana area, which will serve as an alternative traffic route during the future demolition and reconstruction of the Montelupo-Capraia Bridge deck.
In addition to the bridge on SP 106, the bridge monitoring plan also covers four other critical nodes: the SP 80 bridge over the Bacchiano stream in the municipality of Montespertoli, the SP 128 Calamandrei Bridge over the Arno River between Empoli and Vinci, the SP 11 Motta Bridge between Marcignana and Bassa, and the SP 76 Egola River bridge in the Alberi area of Montaione. This layout covers the Empoli-Valdelsa region.
The goal of this data-driven bridge monitoring approach is to use objectively updated data as a support for public safety. This structural monitoring method provides a reference for other national administrations wishing to modernize their existing infrastructure asset management and control processes.
