Load Path Redundancy is described as:

• A. Continuity of load path from span to span.
• B. If one member were to fail, load would be redistributed to other members and bridge failure would not occur.
• C. Creation of multiple load paths by elements that are mechanically fastened together.
• D. The three main components of a bridge.

Answer: (B)

Load path redundancy means the structure is designed with multiple ways for loads to travel so that if one member fails, the load can still be carried by other members without causing a catastrophic collapse. The statement describing that if a member were to fail, the load would be redistributed to other members and bridge failure would not occur captures this idea precisely. It emphasizes the safety benefit of having alternative load paths that take over when part of the structure is compromised. In practice, designers create redundancy with shared load paths through interconnected girders, diaphragms, and bracing so the bridge remains stable even after local damage. The other descriptions touch on related ideas, like continuous load transfer along spans or methods to create multiple paths, but they don’t directly express the key outcome of redundancy—that loads can be redistributed to prevent failure when a component loses capacity.
