During an inspection, what are signs of poor joint condition?

Visible gaps, misalignment, and rust are clear indicators of poor joint condition during a bridge inspection. These signs suggest that the joints are not functioning properly, which can lead to significant structural issues if not addressed. Gaps indicate that the joints may have experienced movement or expansion that could compromise their integrity, while misalignment reveals that the components of the bridge are not properly fitting together, potentially leading to uneven load distribution.

Rust is also a critical sign, as it signifies corrosion of the metal components within the joints, weakening their structural capacity. When inspectors notice these signs, they recognize the potential for further deterioration, which necessitates immediate attention to maintain the safety and longevity of the bridge.

In contrast, the other options reflect conditions associated with good maintenance and structural integrity rather than signs of deterioration. Consistent alignment suggests that the components are properly fitted together, freshly painted surfaces typically indicate recent maintenance, and strong connections to the substructure suggest that the joint is serving its purpose effectively. These elements would not be associated with poor joint condition.
