Crews repair a bridge in Missouri.
A recent analysis of the federal National Bridge Inventory shows that 65,605 bridges are classified as “structurally deficient” and 20,808 are “fracture critical,” the Associated Press reported.
Of the 607,380 bridges in the inventory, 7,795 are rated as structurally deficient and fracture critical, AP reported Sept. 16.
A bridge is classified as fracture critical when there are no redundant protections and could collapse if a vital component fails. A bridge is structurally deficient when it is in need of rehabilitation or replacement because at least one major component of the span has advanced deterioration, the AP reported.
