Sensors save Fürth traffic: This is how you monitor the Zirndorf Bridge!

The hour of technology has arrived in Fürth: the dilapidated Zirndorfer Bridge is monitored using the most modern sensors in order to detect a possible collapse at an early stage. The reason for these preventive measures is a recent report that points out the high risk of the bridge collapsing. The bridge has therefore been completely closed since mid-November 2025. But the good news for road users: The important traffic routes under the bridge, especially on the Main-Danube Canal, can continue to be used unhindered. nn.de reports that the monitoring is intended to ensure that up to 45,000 vehicles can pass the southwest tangent every day.

What exactly is happening under the bridge? Special sound detectors, a total of 32 from MKP GmbH in Weimar, were installed to monitor the critical structure of the bridge. These sensors have the task of registering cracks in the tension wires that form the load-bearing element of the bridge. The technical surveillance costs around 250,000 euros - a price that the city of Fürth is happy to invest in the safety of its citizens.

Early warning system for more safety

As the reporting from br.de adds, the passage under the bridge is only closed in the event of acute deterioration in the building structure. It is planned that the Zirndorfer Bridge will remain accessible until the end of 2026. However, due to the new findings from the report, the demolition and construction of the bridge will be brought forward. Demolition work could begin in spring 2027, although this has not yet been officially confirmed.

The expert teams carrying out the monitoring not only bring local experience with them. You have already taken a close look at the Carola Bridge in Dresden. Such experiences are invaluable in times of ever-increasing traffic volumes.

Technological advances in infrastructure

A look beyond the region's borders shows how modern bridge monitoring has become. For example, the OpenLAB bridge in Bautzen uses over 200 sensors that collect data about temperature, inclination and movement in real time. Developed by the Technical University of Dresden, the goal is to ensure a safe and long-lasting infrastructure. Artificial intelligence helps detect potential damage early, which could be a crucial step not only for the OpenLAB bridge, but also for future monitoring of all bridges. The Federal Ministry of Digital and Transport supports such innovations in order to increase safety in traffic areas and at the same time minimize costs.

The Zirndorf Bridge is a prime example of how modern technology and careful planning go hand in hand to guarantee the safety of road users. The city of Fürth has shown a good hand here by relying on a technical solution that could save lives in an emergency.
