The SIS consortium, comprised of Fininc (51%) and Sacyr (49%), has been awarded the construction of S.S. 340 Regina – Tremezzina bypass, a 9.5-km stretch of highway in the Como province of northern Italy. The contract amounts to 388 million euros with a completion deadline of five years.
The project, awarded by the public firm ANAS, entails an alternative route intended to circumvent traffic in the towns of Sala Comacina and Tremezzina. The total stretch of road is 9.55 km in length, divided into three tunnel sections built mainly of rock:
- Comacina tunnel: 3,489 meters
- Perlana tunnel: 1,908 meters
- Tremezzina tunnel: 2,568 meters
The section corresponds to a conventional suburban bypass with one lane in each direction. The tunnel sections will include the construction of two parallel tunnels: one principle tunnel with a diameter of 11.6 meters, and a parallel emergency route 5.6 meters wide.
