Preparations for the raising of the deck for the Annunziata viaduct are complete. Meanwhile, other works are being carried out on the major project along the Calabrian section of the SS 106 that will transform it into a modern dual carriageway.
Among the most complex and iconic works of the Third Mega Lot, the Annunziata viaduct spans over 900m with a single carriageway and features a distinctive two-level steel-concrete composite deck, one for each direction. In recent weeks, the Ferro viaduct reached its own milestone: standing 20m tall and stretching over 500m, it features a mixed steel-concrete structure with 11 spans. Its construction required 2,800tonnes of steel and more than 23,000m3 of concrete, showcasing the engineering commitment behind the entire Mega Lot.
Construction continues in parallel on four other viaducts – Straface, Monaco, Forno, and Stellitano – as well as on the iconic Avena viaduct, the most architecturally significant overpass of the entire infrastructure, featuring distinctive V-shaped steel piers. Asphalt laying also continues between the Sibari and Trebisacce junctions along the first 18km. Once the auxiliary works being carried out by ANAS are completed, they will allow for early traffic opening ahead of the final completion. In the coming weeks, the second diaphragm of the Trebisacce Tunnel, approximately 3.3km-long and twin-tubed, is scheduled to be broken through, while excavation and lining works continue on the other 10 artificial tunnels along the route.
