Most suspension bridges in use today have cables composed of thousands of steel wires and most of these bridges are aging and carry high volumes of traffic. Deterioration of the elements of the suspension system is a problem, replacement of these elements can be expensive and problematic, while failure could be catastrophic.

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 353: Risk-Based Inspection and Strength Evaluation of Suspension Bridge Main Cable Systems helps develop guidelines for inspection and evaluation of suspension bridge main cable systems using probabilistic approaches.
