Extreme heat is damaging America's transportation infrastructure
Record heat in summer 2024 is straining America’s infrastructure, causing issues like stuck bridges and buckling roads, and disrupting transportation systems.
Suyun Paul Ham writes for The Conversation.
In short:
- The Third Avenue Bridge in New York jammed after metal expansion caused by heat, and roads in Washington and Wisconsin have buckled, disrupting traffic.
- Amtrak and other rail systems face delays due to heat-induced rail expansion, which can cause derailments and safety hazards.
- Engineers are using innovative solutions, including heat-resistant materials and advanced monitoring systems, to address these challenges.

Why this matters:
As climate change intensifies, extreme weather events will increasingly threaten aging infrastructure, leading to safety hazards and costly disruptions. Effective engineering solutions and timely maintenance are vital to enhance the resilience of critical transportation networks.
