Tunnels

Thanks to its technological expertise COMSA has the capacity to undertake complex projects such as the construction of railway and highway tunnels.

COMSA EMTE is also present in this field through its subsidiary, Nortúnel, a company specialising in tunnel construction and underground works. In recent years both companies have executed significant works, such as the Vielha Tunnel (Lleida), the Les Fosses Tunnel (Girona) and various railway tunnels on the Spanish high speed network.
