Tranche 781 "Lugano-Bellinzona Viaduct" involved the construction of a viaduct with a total length of 1,010 m.

Special foundation works were carried out for its construction such as:
- bored piles and jet-grouting consolidation
- substructure works (plinths, "Vigana" shoulders and portal, support elements)
- superstructure works (intermediate V piles and pre-stressed reinforced concrete box-section deck)

Special services were also provided for lifting the deck and the supply and installation of the railway ballast.
