Italy has granted final approval for the construction of the world’s longest suspension bridge, a major infrastructure project set to connect Sicily with the Italian mainland across the Strait of Messina. This long-awaited plan comes with a budget of approximately €13.5 billion, equating to around $15.5 billion, and reflects a central government effort to boost economic development in southern Italy while advancing national engineering prestige.
Design and Features of Italy’s Messina Bridge Project
Once completed, the bridge will span nearly 3.7 kilometres (3,700 m) in total length, with a 3.3-kilometre suspended span a full 1.3 km longer than the current record holder, Turkey’s Çanakkale Bridge. The structure will feature six lanes for road traffic, two emergency lanes, and two railway tracks, capable of handling up to 6,000 cars per hour and 200 trains per day. Towers reaching nearly 399 metres in height will anchor the suspended span, and the deck will measure approximately 60 metres wide.
Designers conducted rigorous environmental and safety assessments. The Environmental Impact Assessment (EIA) was completed with a series of 62 conditions for monitoring and mitigation. Geological studies found the bridge’s anchoring sites to be stable and compliant with seismic codes. Wind-resistance tests confirm the deck can withstand gusts up to 270 km/h, well above recorded local development.
Messina Bridge Timeline and Economic Impact
The project has a long history of approvals and cancellations spanning decades since initial proposals in the 1960s. The most recent revival came under Prime Minister Giorgia Meloni’s administration in 2023, with final government approval granted on August 6, 2025.
Preliminary works such as site studies and access roads could begin between late September and early October 2025, pending final audits. Full-scale construction is expected to launch in 2026. The projected completion window spans between 2032 and 2033, with some reports indicating opening as early as 2032.
Secretary of Infrastructure Matteo Salvini described the bridge as “the biggest infrastructure project in the West,” while Prime Minister Meloni called it an “engineering symbol of global significance” and “an investment in Italy’s present and future.” Government figures estimate the bridge and accompanying works will generate up to 120,000 jobs annually, fueling growth in the economically underdeveloped Mezzogiorno (southern Italy).
