Bridge Collapses: A Growing Concern
Historical Data and Trends
From 1960 to 2015, there were 35 major bridge collapses worldwide due to ship or barge collisions, resulting in 342 fatalities. In the United States, the American Society of Civil Engineers estimates that 46,000 bridges are in “poor” condition, and 17,000 are at risk of collapse from a single hit. These statistics highlight the need for urgent attention to bridge maintenance and repair.
Causes of Bridge Collapses
Extreme Weather, Heavy Trucks, and Collisions
Extreme weather events, such as earthquakes, hurricanes, and elevated heat, pose significant risks to US bridges. Additionally, heavier trucks and collisions from larger container ships strain bridge structures, increasing the likelihood of collapse. The Francis Scott Key Bridge in Baltimore, which collapsed in 2024, is a recent example of the devastating impact of such incidents.
Impact on the Economy and Communities
Financial Consequences and Social Vulnerability
Bridge collapses have substantial financial consequences, affecting local businesses and the broader economy. The closure of the Francis Scott Key Bridge, for instance, will impact over a million people in the Baltimore area, disrupting commuting patterns and affecting the Port of Baltimore’s operations. Socially vulnerable populations are disproportionately affected by such disasters, making it essential to prioritize their needs in emergency response and recovery efforts.
