The existing bridge from 1965 no longer met the requirements with respect to stability and safety. To this end, the existing trough, consisting of steel girders and backfill concrete, was replaced by a wider trough with load-dissipating borders. The track geometry was also modified to achieve a better routing of the BLS route.
To allow the prefabricated bridge elements to be installed safely, the canal had to be completely dammed with sheet piling and the water drained from the excavation pit with piping.
Both banks were then repaired.
