Last weekend, one of our most emblematic works was featured in the press.“The latest major tunnel of Bilbao” was the title given by El Correo to the information on the Arnotegi tunnels which appeared on the front page. Moreover, Deia highlighted the good rate of progress and the large figures involved in this important investment.
These works are being carried out within the second phase of the extension of the Supersur. The main part involves the tunnels which will join El Peñascal and Bolintxu. A double gallery whose construction has included the latest innovations in underground work. Three years of work and a distance of almost 2,000 metres excavated to complete this important road structure.
