In the past few days it has been available. the go-ahead for the Strait Bridge has arrived with the publication of the decree in the Official Gazette. Therefore, it seems that the project for the construction of this infrastructural work on which there has been discussion and controversy for many years is really starting again. After the last technical insights, it's time to get ready to go. The text that had been approved in the Council of Ministers a few weeks ago with the formula “subject to agreements” was substantially confirmed.
The Ministry of Infrastructure and Transport speaks of a “historic choice”.
It is a historic choice, which opens up to a world-record infrastructure with a strong green connotation: the bridge will allow; a drastic reduction in CO2 pollution and a significant drop in discharges into the sea.
When should construction sites start? The goal would be to start the works by the summer of 2024.
THE COSTS OF THE PROJECT
The ministry also speaks of the costs of the work which they will be significant. In fact, an estimated cost of 10 billion euros.
The cost for the construction of the bridge and all the railway and road access works on both sides is today estimated at 10 billion. The difference, huge, is; that the bridge is an investment with very long-term benefits for the whole country-system with particular reference to the South. Especially in the light of the interventions, already planned, to modernize the railways in Calabria and Sicily with speeding up and high-speed/high-capacity sections. With the completion of the high-speed train, in the two regions and the commissioning of the bridge, it is estimated that the journey times from Rome to Palermo will halve, today equal to 12 hours, of which an hour and a half only for the ferrying of the wagons. Significant savings for citizens, businesses and logistics.
As regards the layout of the bridge, the current project involves the construction of a structure of the type "suspension bridge". The ministry speaks of a length of the central span between 3,200 and 3,300 meters, compared to a total length of 3,666 meters.
The stable crossing on the strait is was designed according to the scheme of the suspension bridge. The currently available technical project consists of approximately 8,000 drawings and provides for a length of the central span between 3,200 and 3,300 meters, compared to a total length of 3,666 meters including the side spans, 60.4 meters width of the deck, 399 meters in height of the towers, 2 pairs of cables for the suspension system, 5,320 meters in total length of the cables, 1.26 meters in diameter of the suspension cables, 44,323 steel wires for each suspension cable, 65 meters in height of navigable channel central for the transit of large ships, with an anchor block volume of 533,000 cubic metres. of 6 road lanes, 3 for each direction (2 + 1 emergency) and 2 railway tracks, for a capacity of 1000 kg. of the infrastructure equal to 6,000 vehicles/hour and 200 trains/day. In addition, the structure is; was designed with an “earthquake resistance equal to 7.1 on the Richter scale, with a “third generation” aerodynamic deck; stable up to speeds wind speed of 270 km/h”.
