Bridge on the A45 in Wilnsdorf: explosion for a new construction project!

On Sunday, March 30, 2025, the 377 -meter -long valley bridge of the Landeskroner Weiher on the A45 is blown up near Wilnsdorf. This crucial step is part of a comprehensive construction project to renovate and improve dilapidated Talbrücken in North Rhine-Westphalia. The explosion is planned for 11:00 a.m., with the bridge overturning 36 meters vertically into the depth. Preparations for this spectacular event have been running since the end of last year and include extensive measures to ensure security during the course of the process, such as n-tv.de reports .

The bridge is not only an important traffic artery, but also part of one of the largest construction projects on motorways in NRW. In this context, numerous other dilapidated valley bridges along the A45 must also be renewed. Further new construction projects are planned nearby, including the Talbrücke Rahmede near Lüdenscheid.

preparations and security measures

around 50 kilograms of explosives are used for the demolition, which are placed in 336 previously drilled holes. The use of 7,600 cubic meters of earth as a fall bed is intended to dampen the vibrations caused by the explosive. To ensure that everything runs smoothly, the organizers have created a detailed schedule. Among other things, this provides for the following steps:

• 10:45 a.m.: First explosive signal (long fanfare tone).
• 10:55 a.m.: Second explosive signal (two short fanfare tones).
• 10:58 p.m.: Inflammation blast (loud bang to displace birds).

In order to ensure the security of the citizens, the A45 between the Wilnsdorf and Haiger-Burbach junctions is closed in both directions from 9:00 a.m. to 4:00 p.m. Deadover routes are signposted, whereby the U34 leads towards Dortmund via the B54 towards Frankfurt and the U21 via Würgendorf, Gilsbach and Wilden (L723). In addition, a security zone with a radius of 300 meters was set up around the bridge, which is secured by over 30 shut -off items of the THW. On this day, the access to the "Landeskroner Weiher" hiking parking lot is not possible, and an absolute ban on stopping in the vicinity of the bridge applies.

effects on traffic

The blasting of the bridge and the associated safety measures will result in significant impairment of traffic. Drivers are urgently asked to use the signposted diversions and to adapt to possible delays. The responsible authorities have emphasized that the security of residents and passers -by has the highest priority.

The Talbrücke Landeskroner Weiher symbolically stands for the challenges in front of which the infrastructure is facing Germany. The replacement building, which was completed a few months ago, is a glimmer of hope for modern traffic routing. Preparations and the expiry of the explosion are the result of intensive planning and show how important the preservation of the transport infrastructure is for the region. For more information about the replacement new building and the background of the project, interested parties can visit the website of Autobahn GmbH Federal Republic of Germany, such as Autobahn.de here . The dismantling and construction of the bridges are not only a technical challenge, but also essential for traffic safety and the development of the region.
