Tunnels

26

Our experts have built more than 500 km of tunnels throughout our activity. Our experience in large works and infrastructures also includes the construction of all types of tunnels: road, hydraulic, and railway tunnels, underground tunnels, etc.

A tunnel boring machine lets us excavate in a single operation. Over the years, we have participated in projects like the Silvertown tunnel (London), the Espiño tunnel (AVE Madrid-Galicia), the M30 tunnels (Madrid), and the New York subway (US).
