What is one key visual indicator of bridge end deterioration?

One key visual indicator of bridge end deterioration is the settlement or tilt of bridge approaches. This phenomenon often occurs as a result of underlying issues such as erosion, soil displacement, or structural deficiencies. The bridge approaches, which connect the main structure to the roadway, may be affected by changes in the underlying support, leading to visible settlement or a noticeable tilt.

This is critical because such physical changes can compromise the alignment and structural integrity of the bridge, potentially affecting its overall safety. A tilt or settlement may suggest deeper problems that could impact load-bearing capacities and structural durability over time. Therefore, observing these signs is vital during inspections, as they can indicate serious deterioration at the junction where the bridge meets the approaches, highlighting the need for further inspection or remediation actions.
