The SIS consortium, 51% owned by Italy’s Fininc and 49% by Spain’s Sacyr, has been awarded a €388m road-building contract by public firm Anas in the Como province of northern Italy.
The 9.5km bypass will create an alternative route to circumvent traffic in the towns of Sala Comacina and Tremezzina.
The project to build state road 340 involves boring three tunnels through rock, including the 3,489m Comacina tunnel, the 1,908m Perlana tunnel and the 2,568m Tremezzina tunnel.
Each tunnel, with a diameter of 11.6m, will have a parallel emergency tunnel 5.6m wide.
Work on the project is due to be completed by 2026.
