The Brenner Base Tunnel: Innovative approaches for longevity, safety, and operational efficiency

Abstract The Brenner Base Tunnel is considered one of the most significant infrastructure projects of the century, driven by continuous development and innovative solutions. These improvements span all phases of the project, from planning to operation, allowing for new, contemporary requirements to be addressed even during construction. Special attention is given to innovative technologies that enhance the tunnel's efficiency, safety, longevity, and maintainability. This article discusses various innovations, such as advanced materials, modern monitoring systems, and techniques that enable safe tunnelling even under challenging geological conditions. The Brenner Base Tunnel is thus not only a technical marvel but also a model for future infrastructure projects that must be designed for long‐term sustainability.
