NLife is always in danger.In the sick southern half, the pier collapsed uncontrollably laterally Salzbachtal Bridge Not ruled out even after six weeks of blocking. At the same time, the rest of the bridge supports have been fixed with concrete pads, and steel corsets made of red auxiliary supports have been installed. But this is not enough to eliminate the 50-meter safety zone around the bridge.
According to Autobahn GmbH, in order to urgently stabilize the pillars, another corset made of shotcrete is needed, which must harden for a period of time. It is expected that the building will not be approved by an external test engineer until mid-August, rather than the end of July. Finally, experts can inspect the bridge directly, not just from a safe distance. Only then can the blast hole be drilled.
Necessary evacuation concept
As a result, the long-awaited start of the new building was further postponed. Initially, according to Autobahn GmbH, the bridge should be secured within two weeks in order to begin preparations for demolition, which is estimated to take six to eight weeks. The preparations include the use of large amounts of sand to protect major sewage treatment plants, railway tracks and other infrastructure. The demolition date is planned for early or mid-September. It should be four weeks from now. Prior to this, all buildings in the area will be inspected so that any damage after the Big Bang can be determined without a doubt. Since the safety distance of 250 meters must be observed during the explosion, an evacuation concept is also required. The concept of blasting itself is not well known; it was previously thought that the south bridge was demolished and then the north bridge was laid on it.
Demolition will be an annual event in Wiesbaden. An incident where suffering commuters have high hopes. At that time, the new construction of the South Bridge can start. Experts optimistically estimate that it will only take one year. An unusually short period of time that Alexander Pilz of Autobahn GmbH will not bet on. But the foundation of the new bridge has been laid, and the components of the new steel bridge have been pre-installed. The construction distance of the New North Bridge should also be as short as possible.
The fact that a bridge opened in 1963 was so dilapidated in less than 60 years that it was about to collapse before the planned renovation began. This fact remains a matter of contention in the state capital. The Salzbachtal Bridge was able to pass 20,000 cars per day, and it was built as part of the so-called Southern Bypass. Wiesbaden is closer to Frankfurt via the Rhein-Main-Schnellweg A66. However, around 20 years after it was opened to traffic, the bridge had to be reinforced for the first time due to the increasing traffic volume, and again in 2010. At that time, it had been considered a problem child by engineers, and it was already clear that the bridge would not be able to withstand the load for a long time. A new building was planned, but it was not publicly announced until 2017. It was assumed that two and a half three-lane bridges would be demolished and the four-lane bridge would be rebuilt as early as 2023.
