Messina Bridge
The Beating Heart
The deck of the Messina Strait Bridge is the beating heart of a work that defies limits and imagination. With its 3.3 km suspended and an unprecedented width, it supports six road lanes and two railway tracks, connecting Calabria and Sicily. Every detail, from the aerodynamic profile to the materials, tells a story of Italian engineering challenge, destined to become a new global symbol of progress and beauty.
An Absolute Record
Messina Bridge
The deck of the Messina Strait Bridge represents the structural and symbolic heart of the entire work, the element that makes it possible to transform a visionary idea into concrete reality. With its 3,300 meters suspended between the two shores, it will be the world’s longest single span, an achievement that far surpasses any other suspension bridge existing today. Its exceptional width, approximately 60 meters, will accommodate six road lanes – three per direction – and two central railway tracks, offering a multimodal platform unique of its kind.
The deck was conceived not only to ensure maximum traffic efficiency but also to harmoniously integrate road and railway functions, allowing the passage of light vehicles, heavy goods vehicles, and high-capacity trains. Every detail of its design is aimed at promoting constant, safe, and comfortable flows, even in the presence of severe weather conditions or high traffic intensity.
Thanks to the use of innovative materials and a carefully studied aerodynamic profile, the deck combines solidity and lightness, standing as one of the greatest examples of contemporary structural engineering, destined to redefine standards for the great infrastructures of the future as “Messina Style”.

IN DETAIL
Messina Bridge
A Unique Airfoil Profile to Master the Strait
Messina Bridge
The most original feature of the deck is its aerodynamic shape, conceived as a true airfoil profile. It is not a simple horizontal platform: the lines have been shaped to “dialogue” with the Strait’s currents, minimizing turbulence and vibrations. In sophisticated wind tunnels, among the most advanced in the world, hundreds of tests were performed on scale models and high-precision digital simulations. Gusts exceeding 300 km/h, pressure variations, thermal oscillations, and dynamic loads were reproduced to verify the structure’s response. The result is a deck with extraordinary and still unique characteristics worldwide, capable of maintaining stability and comfort even in extreme weather-climate scenarios.
Cutting-Edge Materials and Construction Processes
Messina Bridge
To build this gigantic “steel wing,” ultra-high-strength steels will be used, treated with advanced anti-corrosion systems, essential for facing the marine environment of the Strait. The segments composing the roadway will be prefabricated in factories, transported to the site, and assembled at height via electronically controlled lifting procedures. The connections with the vertical suspenders, which hang them from the main cables, will require millimeter precision, ensuring faster installation times and reduced impact on coastal areas.
The Exclusive Design: The 'Messina Style'
Messina Bridge
The deck was developed according to the so-called “Messina Style”, an approach that combines engineering rigor, aesthetics, and landscape integration. The side surfaces are designed to reflect natural light and lighten the visual perception, while the thin and continuous section gives the bridge a unique elegance. This design philosophy is not only about aesthetics: it involves functionality, maintenance, and sustainability, creating a rare balance between innovation and harmony with the surrounding environment.
Stability and Operational Safety
Messina Bridge
The safety of the deck has been an absolute priority from the earliest stages. In addition to wind resistance, the structure is designed to withstand seismic events up to magnitude 7.5 and to manage loads from intense traffic and high-capacity trains. Dynamic damping devices and energy dissipation systems are planned, which protect the infrastructure in case of exceptional stresses. All verifications have confirmed that the deck will be able to operate safely with wide margins compared to regulatory requirements.
Intelligent Monitoring and Predictive Maintenance
Messina Bridge
One of the most innovative elements will be the network of intelligent sensors installed along the entire length of the deck. These devices will collect real-time data on deformations, vibrations, temperature, and environmental conditions, transmitting them to a dedicated control center. The analysis of the information will allow for planning predictive maintenance interventions, reducing risks and extending the structure’s service life, estimated at at least 200 years.
A Symbol of Engineering and Vision
Messina Bridge
The deck of the Messina Bridge is not just a technical element: it is the result of decades of studies, modeling, and international comparisons. Its exclusivity lies in the combination of record dimensions, advanced aerodynamic solutions, and a design that enhances the landscape. When completed, it will constitute a benchmark for future generations of engineers, demonstrating how research, aesthetics, and technology can merge into an infrastructure that redefines the boundaries of science and technology in the service of mobility.
