Abstract The Bronzolo Tunnel will have a total length of 702 meters and represents a central component of a large‐scale bypass project aimed at significantly improving the quality of life for residents in the communities of Leives, Pineta di Laives, and Bronzolo (see cover image). The tunnel will be constructed using mining techniques in loose rock, employing the proven AT ‐ Pipe Umbrella System, which provides additional stability and safety during construction (see illustration above). More detailed information about the tunnel construction project can be found on pages 320‐321. (Source: Sandvik Ground Support – mining.sandvik/groundsupport, Photo: STRABAG)
