The Brenner Base Tunnel with a total of 230 km of tunnels is a geological, structural and logistical challenge. The transnational project is an additional challenge, considering different planning, approval and construction rules and cultures. From the start of construction in 2007 to the present, today halftime is reached with 100 excavated tunnel kilometers. An overview of selected topics is given in this contribution, such as project optimizations of the emergency areas, geological/geotechnical knowledge transfer from the already driven exploratory tunnel to the following construction lots of the parallel main tunnels, reprocessing and use of Schists as aggregates for the inner lining and shotcrete production, logistics experience with wheel‐bound transport vehicles, measurements during construction with laser tunnel scanners and the service life of the tunnel of 200 years with an increased safety concept defined in the guide conceptual design. Preparations and planning are already at an advanced state for the second half of the project, concerning the next excavation lots, secondary linings as well as interior work with the installation of the technical equipment. The construction work is expected to be completed in 2025 and the end of construction is expected at the end of 2028 (2030 in case of risk occurrence).
