VALICO BYPASS - LOTS 6 AND 7

Client: Autostrade per l'Italia S.p.A.

Cost of works: € 548,619,312

Upgrading of the Apennine section between Sasso Marconi and Barberino di Mugello, along the La Quercia - Badia Nuova section.

Work on lots 6 and 7 consists of the construction of a new section of motorway of approximately 7.5 km, 2 twin-tube tunnels with an overall length of approximately 4.5 km, and 2 viaducts made of mixed-section, steel and concrete deck, with built-in anti-seismic devices. The work also includes 1200 m of embankment and minor road works.

The Molino di Setta viaduct is of especially high quality, a mixed steel and concrete deck that is 530 m in length and reaches over several spans with a maximum central span height of 100 m. The same applies to the Sparvo viaduct, built in mixed steel and concrete, also 500 m in length, with a central span of 120 m.

In addition to the Val di Sambro tunnel, excavated using traditional methods, with a lenght of 2 km per tube, the main project on this lot is the twin-tube Sparvo tunnel. The North carriageway is 2564 m long and the South carriageway is 2600 m long. The two tubes will each house 3 lanes and a pedestrian bypass and driveway are also planned in case of emergency rescue or evacuation.

The Sparvo tunnel has been excavated with the help of 'Martina', an EPB TBM that was specifically designed for this project. It has an excavation diameter of 15.62 m and is equipped with anti-explosive devices.
