In America, 46,000 bridges have aging structures and are in “poor” condition, and 17,000 are at risk of collapse from a single hit, according to the American Society of Civil Engineers and the ...
This is a list of structural failures and collapses of buildings and other structures including bridges, dams, and radio masts/towers. This is a dynamic list and may never be able to satisfy particular standards for completeness.
The bridge was built in 1955, as part of the state government's upgrades to the U.S. Route 99 corridor and a year before the Interstate Highway System was begun. The bridge carries four lanes of traffic, two lanes in each direction separated by a median barrier. The portions over the river are four consecutive spans, each 160 feet (49 m) long.
Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
With temperatures reaching record highs in 2024, the U.S.’s aging bridges are feeling the heat. A Quarter of America's Bridges May Collapse Within 26 Years. We Saw the Whole Thing Coming.

The NBI can classify bridges as "structurally deficient," which means that the condition of the bridge includes a significant defect, which often means that speed or weight limits must be put on the bridge to ensure safety; a rating of 4 or lower on any of items 58, 59, 60, or 62 (deck, superstructure, substructure, and culverts, respectively ...
In “Our Kindred Creatures,” authors Bill Wasik and Monica Murphy explore the origins of the animal welfare movement and follow the activists who influenced how we treat dogs and cats today.
