Traffic chaos in the Lake Constance district: Ten bridges are under scrutiny!

From June 3rd, the Lake Constance district will be dedicated to bridge inspections. The main inspection of a total of ten bridges along the B31 will be carried out over four weeks. Loud South Courier This can lead to significant traffic delays because a lane is closed during the work. The tests take place every six years and are essential to ensure the load-bearing capacity, stability and traffic safety of the bridges.

But how does such a test work? The check is comparable to the TÜV test of vehicles. Structural inspectors pay attention to signs of wear and tear caused by traffic, weather and de-icing salts. A specially developed bridge underside device, which is 13 meters long and 4 meters high, is used to reach the underside of the bridges. Traffic is routed alternately past the test vehicle.

Planned exam period

The exams are scheduled until July 3rd and include the following bridges:

• 30. Juni: B31, Löwentalviadukt in Friedrichshafen
• 1. Juli: B31, Brücke über die Argen bei Langenargen-Oberdorf
• 1. Juli: B31, Schussenbrücke bei Eriskirch
• 1. Juli: B31, Brücke über den Nonnenbach bei Kressbronn
• 2. Juli: B467, Brücke über Gemeindestraße und Wirtschaftsweg bei Tettnang
• 2. Juli: B467, Brücke über die Bahn bei Tettnang
• 2. Juli: B467, Brücke über die Argen bei Kressbronn-Gießen
• 3. Juli: B30, Brücke über die Rotach in Friedrichshafen
• 3. Juli: B30, Brücke über die Schussen bei Meckenbeuren-Lochbrücke
• 3. Juli: L329, Brücke über die Schussen in Meckenbeuren-Brochenzell

According to the experts at DEKRA Regular inspections of bridge structures are not only advisable, but also required by law. These tests are carried out in accordance with DIN 1076 and aim to detect damage at an early stage and ensure road safety. The comprehensive condition of the bridges and any defects are documented using techniques such as photographic evidence and condition assessments.

View of the future

What do these controls mean for the security of the infrastructure? Regular bridge inspections are crucial to ensure the stability of engineering structures. According to the information from Biberger Support structures, bearings and transitions must be thoroughly checked for cracks, corrosion and material fatigue. Special tests are required, especially after extraordinary events or suspicious circumstances. For example, the partial collapse of the Carola Bridge in Dresden in September 2024 became a reminder of the importance of these regular checks.

By using the latest technology such as drones, sensors and mobile stages, the safety of the bridges is continuously monitored. The early detection of damage is crucial in order to protect human lives and plan renovations in a timely manner. This shows that the safety of the bridges in the Lake Constance district is the focus and is taken seriously.
