The project plan of HERING Bahnbau was correspondingly demanding. A new bridge was constructed about 25 metres next to the existing bridge. During the closure period, the existing overpass was demolished, the new bridge was moved into its final position and finally lowered by 1.60 metres - a question of prudent planning and optimum timing. But it got even more exciting.
The installation of the bored piles once again placed the highest demands on the HERING team. Twelve bored piles - six of them with a length of eleven metres each - were installed through the old foundation. When the bridge was lowered, the openings in the frame walls specially made for this purpose had to fit exactly into the bored pile heads - work requiring millimetre precision. And we did it!
The strong and close cooperation of all those involved in the project made it possible and railway operations were able to be resumed safely and on time. Chapeau, HERING Bahnbau!
