Autostrade per l’Italia has finally opened the long-awaited third lane of the A1 between Firenze Sud and Incisa, a very important section for Italian mobility. It is about 5 kilometers of upgrading the route – both towards Rome and towards Bologna – as part of the larger development project of the Tuscan node of the Autostrada del Sole, between the Barberino and Valdarno junctions, and related to the Variante di Pass (for a total length of approximately 120 km).
The section is characterized by an extension on site to three lanes in each direction of travel – each of 3.75 meters – plus a 3-meter emergency lane, for a platform width of about 15 meters compared to the 10 meters of the original route. According to Autostrade, two important engineering interventions are part of the upgrading of the route: the Ema viaduct, (between km 302 + 161 and km 302 + 233) and the Antella tunnel (between km 304 + 500 and km 304 + 790). The Ema bridge was enlarged thanks to the construction of a new deck placed alongside the two existing ones, to obtain a single carriageway with three lanes, plus the emergency lane. Due to its location, exposure and morphology, the roof of the Antella tunnel, which will be built in 2022 after a project conceived in coordination with the Municipality of Bagno a Ripoli, will look like a real green terrace, where it will be There is also a parking lot.

The work, carried out under the supervision of the granting Ministry, involved over 100 technicians a day, divided between Pavimental, the construction company of the Aspi group, and other 30 contractors, for about 1.25 million hours, guaranteeing in all phases of the works the passability of the section, in both directions of travel. The activities of this phase will be completed by 2021, with the opening to traffic of the remaining 1.5 km of extension, from the Chianti service area to the end of the lot, at the Church of San Giorgio a Ruballa. The works had started in May 2017.
The president of Aspi, Giuliano Mari, declared, according to what Il Sole 24 Ore reports: “All this set of activities, for new investments but also for maintenance and modernization of the network, cause the opening of as many construction sites and the high number of the same has heavy repercussions on traffic. We are perfectly aware of this, but we are also aware of the fact that safety, together with mobility, are an unavoidable necessity and we are obliged to follow this line.“.
