N04 Axenstrasse, Schiferen/ Schiferenegg Bank Reinforcement

The existing bank reinforcement along the Axenstrasse road at Schiferen/ Schiferenegg are showing signs of damage (partly due to erosion). To protect the bank and guarantee safe roadholding the section was repaired (concrete bars with micro pile foundation on steep  slopes or block chains with tie-back anchors on the flat banks). Works were coordinated with the spawning season of the whitefish.
