A new bridge overnight.
The goal of this project was to demolish the existing railway bridge over the Remisenstrasse in Zurich, and to replace it with a new bridge and an auxiliary bridge. In order to avoid interruptions to rail and road traffic, the team prefabricated the two required sections of bridge on-site adjacent to the intended location, and then lifted them into position.
Just one night saw the complete "showdown" for this one-year project. Both 170 tonne elements were individually moved by one of the largest tracked cranes in Switzerland, positioned with millimetric precision, and joined with quick-setting concrete. In May 2017, this bridge project was rated first-class by the client, Swiss Federal Railways.
To position the 170 tonne bridge slabs, the PORR team made use of one of the largest tracked cranes in Switzerland.
