Bracons Tunnel

Bracons Tunnel

Barcelona, Spain

Service: Detailed Design, Construction Supervision and Health and Safety Coordination
Client: GISA – Infrastructure Administration of Catalonia
Period: 2004 – 2009

GPO provided construction supervision services for a 16.5 km long segment between Torelló and Olot. The alignment was designed to minimize environmental impact and to integrate the road into the landscape. This new section was designed as a conventional two-lane road, with one lane for each direction, and access control to the surrounding properties. The most significant part of this project was the Bracons Tunnel, a 4.6 km long, two lane tunnel. The project included four other tunnels between 90 and 520 m. All tunnels, including Bracons, were constructed using the New Austrian Tunneling Method. The structures along this segment included: two cut and cover tunnels and three viaducts, the longest called Les Salines.
