Brenner Base Tunnel

The Brenner Base Tunnel is a 55 km-long railway tunnel with two parallel tubes, connecting Innsbruck (Austria) and Fortezza (Italy). Together with the South Innsbruck underground bypass, it forms the world’s longest underground railway (64 km). Encardio-rite played a key role in geotechnical monitoring and instrumentation to ensure long-term structural stability and operational safety. Our expertise in tunnel monitoring helped mitigate geotechnical risks in this large-scale infrastructure project.

Brenner Base Tunnel

Encardio-rite was responsible for the monitoring and instrumentation of the Brenner Base Tunnel which is a nearly horizontal rail tunnel with 2 parallel tubes.

55 km long, this tunnel runs between the railway stations of Innsbruck and Fortezza and is connected to South Innsbruck by an underground by-pass. This by-pass and the base tunnel put together are the world’s longest underground railway, with a total length of 64km.
