The CEO of Aspi, Roberto Tomasi: “Tuscany is one of the areas where the work we are carrying out to modernize and strengthen the motorway network is most evident”
Over 250 yellow jackets of the Autostrade per l’Italia Group are employed daily on the construction site where every day they work to give half a meter more light to the new tunnel of San Donato. A 923 meter long infrastructure which represents the engineering pride of the project for the new southbound route of the A1 between Florence South and Incisa. A natural tunnel created with a complex technique, which involves a traditional excavation, already conducted for 30 meters of extension, carried out simultaneously from both entrances, with the aim of optimizing execution times and not limiting full transitability of the two adjacent galleries. This morning the construction site was visited by a delegation made up, among others, of the Deputy Prime Minister and Minister of Infrastructure and Transport Matteo Salvini, and Roberto Tomasi, CEO of Autostrade per l’Italia. The meeting was an opportunity to also talk the advancement of the modernization and redevelopment program of the southern carriageway of the original section of A1, between Barberino and Calenzano.
The construction site operates according to the highest sustainability standards, using recycled steel and guaranteeing full protection of the waters and protected fauna, through the relocation and monitoring of protected species. For the excavation material produced during the construction of the tunnel, total reuse is envisaged in other activities included in the upgrading programme, thus eliminating the percentage of landfill disposal. Maximum attention to the protection and safety of people working on the construction site, thanks to the use of the new “semi-automatic” curtain rod, a structure used to create the vault of the new tunnel that is easier to handle and more stable than traditional components which, during the phases more delicate handling and installation, limits the interventions of technicians, thanks to the aid of mechanical means.
The new infrastructure it is part of the program to widen the third lane on the stretch of the Autosole between Florence South and Incisa Valdarno, a project which overall concerns 17.5 km of route divided into two different lots, the progress level of which today stands at around 30%. The first stretch of approximately 6 km was opened to traffic in 2021, while the second lot of approximately 12 km includes, in addition to the San Donato tunnel, also the construction of two new viaducts: the Ribuio and the Massone, for a total investment of 400 million.
Since last October 8, with the demolition of the deck of the first of the six viaducts present on the stretch, the Torraccia viaduct, we have entered the central phase of the program which also includes the modernization of the caps of all the tunnels present along the stretch (12 fornixes). While the demolition, through the use of explosives, of the Goccioloni viaduct deck has been confirmed for mid-December. The regeneration activities of the stretch’s infrastructure are preparatory to the broader redevelopment program of the entire route, which has already seen the completion of the new carriageway towards Florence with the construction of the Santa Lucia tunnel, the longest three-lane tunnel ever built in Europe.
While in the direction of Bologna, you will travel on four lanes thanks to the reconfiguration of the entire original route of the A1, consisting of two lanes in each direction. For the entire project, an investment of approximately 135 million euros is expected for the modernization and approximately 120 million euros for the reconfiguration. The operation of the sites visited testifies to the progress of Aspi’s plan for the strengthening of the Tuscan motorway network which involves the use of resources equal to 6.3 billion euros, of which works worth almost 4 billion euros have already been carried out. Other planned interventions include the construction of the third lane of the A11 Florence-Pistoia, where preparatory works are underway, and the widening of the A1 between Incisa and Valdarno.
“Tuscany is one of the areas where the work we are carrying out to modernize and strengthen the motorway network is most evident. Here in the last two years we have completed new works worth 1.3 billion euros and, in 2023 alone, there were more than 1 million hours of activity on construction sites”. This was underlined by the CEO of Aspi, Roberto Tomasi. “In recent years we have worked to make the network of this region increasingly modern, which constitutes the fundamental hub for mobility between the South and North of the country. Our objective – he says – is to continue working with commitment and determination, above all to adapt the assets to the current traffic demand. This is an essential action, with a view to the sustainability of the journey and the economic and social growth of the territories”.
