Thousands Demonstrate Against Planned Construction of the World's Longest Bridge Linking Sicily and Italy
The Strait of Messina Bridge, set to be the world's longest single-span suspension bridge, has received final approval from the Italian government on August 6, 2025 [1][2][4]. The bridge, with a planned main span of 3,300 meters, will connect Sicily to the Italian mainland, featuring six lanes for cars and two railway lines [2][3].
The bridge, slated for completion by 2032, promises to revolutionise transport links between Sicily and mainland Italy. It is expected to save 2.5 hours in transit time for trains, reduce the time to cross the strait by ferry from up to 100 minutes to 10 minutes by car, and surpass Turkiye's Canakkale Bridge by 1,277 metres (1,400 yards) [2].
However, the project remains highly controversial due to several concerns.
Environmental Impact
Environmental groups have opposed the project, citing threats to migratory birds and overall ecosystem disruption. Complaints have been filed with the European Union, and local activists and lawyers have organised protests, including a large demonstration in Messina with around 10,000 participants [1][3].
Seismic Risk
The region is seismically active, and although engineers claim the structure will withstand earthquakes, strong winds, and saltwater erosion, some experts emphasise that the risk cannot be eliminated, only managed [1][3][5].
Social Impact
Approximately 500 families are expected to be displaced by construction, which has fueled local opposition.
Political and Economic Concerns
The bridge project has been cancelled and revived multiple times due to government changes, budget constraints, and concerns about mafia infiltration in construction projects. Critics argue that resources might be better spent investing in local communities rather than on this ambitious infrastructure [1][3].
The current construction contract involves a consortium of companies including Italy's Webuild, Spain's Sacyr, Japan's IHI, and Italian firms Condotte and Itinera [2]. This consortium is tasked with building not just the bridge but also the approach roads and railway connections on both sides of the strait.
As the project moves forward, it remains to be seen how these controversies will be addressed and whether the Strait of Messina Bridge will indeed become a reality.
