KS-2 Tangenvika Jernbanebru, Norway
Short description
The project consists of a new railway bridge between Espa and the Tangen peninsula in Norway.
The project
As part of a new railway link between Kleverud-Sørli-Åkersvika, a new railway bridge will be constructed for the Bane NOR over Lake Mjøsa, between Espa and the Tangen Pennisula.
The bridge design caters for a double-track railway arrangement, with construction works being performed by the Implenia Norway division and when complete will be the longest railway bridge built in Norway (1042m).
The superstructures are being built span by span using the movable scaffolding system (MSS) method. The structure involves 15 spans and will incorporate BBV Systems’ L19 (Coupled) & L22 internal post-tensioned tendon.
The internal bonded BBV PT system is used for the longitudinal post-tensioning of the main bridge superstructures.
