Motorways for Italy inaugurated a work that should immediately give immediate benefits to Italian motorway mobility, in particular with the aim of reducing queues. The company has completed work on the new section of the A1, between Barberino di Mugello and Firenze Nord, heading south. It is a three-lane highway, the new pavement of which is 17.5 kilometers long. Basically, it is the natural continuation of the Variante di Valico.
Here are the data, as communicated by Autostrade. “The new infrastructure strengthens one of the busiest hubs in the country, increasing the capacity (from 4 lanes to 7 lanes) of the section, which sees the passage of over 100 vehicles per minute on average during peak hours. Thanks to this work, the greater fluidity of traffic will result in savings for the community of 1.5 million hours a year, reducing travel time by 30%: the containment of queues and stop and go phenomena will also generate a reduction of CO2 emissions quantifiable in -2,000 tons per year. An average of 500 people worked on its construction every day, for a total of 6 million hours worked. Over a total of 17.5 km – of which 10 km underground – the new section includes three 3.75-meter lanes, plus an emergency lane on the open-air sections. The project is part of the broader development plan of the Tuscan node of the Autostrada del Sole, between the Barberino and Valdarno junctions, which covers a total of 120 km“.
The project, with a total investment of around 1 billion euros, is characterized by 4 main infrastructures, two tunnels and two viaducts: in this context, the Santa Lucia, the longest 3-lane tunnel built in Europe (approximately 7,750 m), excavated with the aid of the largest TBM cutter ever used in the Old Continent. The Baccheraia Viaduct (135 m) and the Marinella Viaduct (550 m) were also built on the new route, as well as the Boscaccio Gallery (2,000 m).
“This is an important day for the country“, Declared Roberto Tomasi, CEO of Autostrade per l’Italia:”The new section of the A1 Barberino-Firenze nord is a strategic asset for the viability and economy of the area, but above all it is an avant-garde from an engineering and construction, environmental and technological point of view. Our commitment to deliver to the country, between now and the next few years, safe, modern infrastructures that meet the needs of citizens, has moved in parallel with an operation of radical change right in the heart of our company“.
