Painted Steel Bridge/galvanized Steel Bridge

According to the latest maintenance guidelines, the frequency of routine inspections for Bailey bridges is usually at least once a year. However, the frequency of inspections may need to be increased if the bridge is in the following conditions:
- **High traffic**: If the bridge is subject to heavier traffic loads, more frequent inspections may be required.
- **Harsh environmental conditions**: For example, in coastal areas or areas with frequent extreme weather, bridges may need to be inspected once a year.
- **Long service life**: As the service life of the bridge increases, its inspection frequency should also increase accordingly.

In addition, if the bridge is used in an emergency or has experienced a major event (such as floods, earthquakes, etc.), additional inspections should be carried out immediately. Regular inspections help to detect and deal with potential problems in a timely manner, ensuring the safety and service life of the bridge.
