The final design was updated through the Designer’s Report, which was approved by the Board of Directors of Stretto di Messina in February 2024.
In particular, the Designer’s Report confirmed the compliance of the  final design with the Preliminary Design and the requirements established at the time of its approval, particularly regarding environmental compatibility and the location of the Bridge. It also highlighted additional updates to be developed in the Detailed Design to align it with the following aspects, in accordance with Law Decree 35 of March 31, 2023:

• technical standards for construction (NTC2018) and the resulting updates to geological modeling and geotechnical characterization;
• current safety regulations;
• specific design guidelines outlined in current design manuals;
• environmental compatibility;
• technological advancements and the use of new construction materials;
• experimental tests as recommended by the Scientific Committee’s opinion on the 2011 Final Design.

In detail, the upgrades identified by the Designer’s Report include:

• development of the detailed design and all subsequent phases of the project lifecycle using BIM methodologies, in compliance with current technical and regulatory standards in both the national and international arenas for the design, construction, and management of major infrastructure projects;
• integration and enhancement of the Structural Health Monitoring System (SHMS), Bridge Management System (BMS), and Management and Control System (MACS);
• integration of continuous monitoring systems for bridges, viaducts, and the Bridge with the structural “Digital Twin” to interpret and predict structural performance, simulate various scenarios, and provide valuable insights for maintenance planning;
• enhancement of the durability of the Bridge’s structures through the use of high-performance concrete, protective coatings, and an improved internal dehumidification system for the steel structures;
• improvements to active and passive fire protection systems for the metal components of the Bridge that may be exposed to fires from vehicles or trains;
• implementation of Smart Road technology, aligning with the EU and national digitalization frameworks for road infrastructure, with advanced levels of driver assistance technologies;
• in the detailed design, definition of a toll collection system consistent with existing technologies used in a number of Italian motorways, such as Free Flow, aimed at reducing community impact and speeding up traffic flow.
