Just when it looked like the future of the long-awaited Marão tunnel had hit another brick wall, construction company Opway – part of the bankrupt Grupo Espírito Santo – has come up with the €1.5 million in “new bank” guarantees needed by Estradas de Portugal to secure the project.
The 5.6 km tunnel linking Amarante with Vila Real has a projected overall cost of €452 million – that’s €800 per centimetre.
