---|---|---|---|---|
Range of damage ratio (Werner et al. 2006) | 1%–5% | 5%–50% | 50%–80% | 80%–100% |
Best estimate of damage ratio (Di) (Werner et al. 2006) | 3% | 25% | 75% | 100% |
Inspection priority (Dukes 2013) | Low | Medium | Medium-high | High |
Likely post-event traffic state (Dukes 2013) | Open to normal traffic- no restrictions | Open to limited traffic- speed/weight/lane restrictions | Emergency vehicles only- speed/weight/lane restrictions | Closed until shored/braced- potential for collapse |
