1. Definition and classification of dangerous bridges
Dangerous bridges refer to bridges that have reduced load-bearing capacity due to structural aging, design defects or natural disasters and pose safety risks. It can be divided into the following three categories according to the degree of risk:
| Hazard level | Feature description | Disposal measures |
|---|---|---|
| Level 1 dangerous bridge | The main structure is seriously damaged and may collapse at any time | Seal and dismantle immediately |
| Level 2 dangerous bridge | Local structural damage requires restricted access | Reinforcement repair + load limitation |
| Level 3 dangerous bridge | There are potential risks that need to be monitored | Regular inspection + maintenance |
2. Inventory of recent hot events (last 10 days)
The following are the dangerous bridge-related incidents that are hotly discussed across the Internet:
| Date | event | heat index |

1.Safety hazard investigation: Netizens in many places reported that there are bridges that are "operating with illness" in their areas.
2.Attribution of supervisory responsibilities: 62% of the discussions involved department collaborative management issues
3.Technology innovation application: New technologies such as Beidou monitoring and optical fiber sensing are highly anticipated
4. In-depth interpretation of typical cases

This incident exposed problems such as lax approval and formality in the management of funds for the reconstruction of dangerous bridges. Related topics are still continuing to ferment.
5. Suggestions from professional organizations
The China Bridge Association recently proposed a "three-step" solution:
1. Establish a national dynamic database of dangerous bridges (completed before the end of 2024)
2. Implement the "bridge chief system" responsibility management system
3. Invest no less than 0.1% of GDP in special maintenance funds every year
Conclusion
The problem of dangerous bridges is not only an inevitable phenomenon of aging infrastructure, but also a touchstone for testing social governance capabilities. With the advancement of new urbanization, how to achieve "dangerous bridges are not in danger" will become an important issue in the field of public safety for a long time. It is recommended that the public actively participate in reporting dangerous bridge hazards through the 12345 hotline and other channels to jointly protect travel safety.
