Completion of the north portal: gigantic challenges in the Sillschlucht!

In an exciting turn in the building history of the Brenner base tunnel, the “Sillschlucht” was successfully completed on in early December 2024 . With only 600 meters length, this segment is one of the shortest sections, but the construction project presented those responsible against enormous logistical and technical challenges. The setting of up to 60 preliminary clamping with a length of up to 120 meters in the rock of the Viller Berg was particularly demanding href = "https://www.ots.at/presseaus-sung/ots_20241213_ots0086/brenner-basistunnel-mit-dem-baulos-sillschlucht-ist-das-nordPortal-made"> OTS reported.

Project manager Martin Keinprecht describes the construction as a complicated ensemble , which from 170 bored piles for the reinforced concrete support wall, three 50 meter long steel bridges , a 55 meter long clamping band bridge for pedestrians and one Stamiler -concrete tunnel exists. This construction project was particularly challenging, since existing infrastructures such as the A12 Inntal Autobahn , the A13 Brenner Autobahn , the Tyrol Panorama Museum and the Untere Sill power plant were in the immediate vicinity href = "https://tirol.orf.at/stories/3285244/"> ORF TIROL holds.

an important step

With a total order of 59.5 million euros , the project was carried out by porr bau GmbH Kematen and successfully completed within the specified construction period of 52 months . The completion of this decisive section of the Brenner Basist tunnel is a great success for the project company BBT SE, whose board members, Martin Gradnitzer and Gilberto Cardola , highlight the importance of the portal structures. "They give the infrastructure project a unique and distinctive face," explains Gradnitzer, while the renaturation of the outdoor area is already underway, so that the hiking trails from spring 2025 should be accessible again.
