Renzo Piano criticizes Messina Strait Bridge design

Architect and senator for life Renzo Piano has raised significant concerns regarding the proposed Messina Strait Bridge project. In an interview with Corriere della Sera, Piano characterized the current design as an 'engineering utopia' and a 'gamble'.

His primary criticism focuses on the decision to utilize a single-span structure exceeding 3.3 kilometers in length. Piano argues that a single span without intermediate supports leaves the bridge vulnerable to extreme environmental forces, specifically the strong winds and resulting vibrations characteristic of the Strait.

As an alternative, Piano suggested a construction model involving support pillars anchored directly into the seabed, a method he notes is widely used internationally. However, current project engineers have previously avoided this approach due to the region's high seismic activity and intense marine currents, which pose significant risks to installing pillars in deep, tectonically active waters.
