The Current State of U.S. Ponti e strade

Understanding the “D-” Rating
You’ve probably heard about the “D-” rating for U.S. infrastructure, but what does it actually mean? IL American Society of Civil Engineers (ASCE) uses a detailed grading system to evaluate infrastructure. Here’s a breakdown of the criteria they consider:
Criteria | Descrizione |
---|---|
Capacity | Measures if the infrastructure can handle current and future demands. |
Condition | Assesses the physical state of the infrastructure. |
Funding | Compares available funding to what’s needed for improvements. |
Future Need | Estimates the cost of upgrades and evaluates future funding prospects. |
Operation and Maintenance | Looks at how well the infrastructure is maintained and operated. |
Pubblica sicurezza | Examines risks to public safety due to the infrastructure’s condition. |
Resilience | Evaluates how well the infrastructure can withstand disasters and recover. |
Innovation | Considers the use of new technologies to improve infrastructure. |
A “D-” rating means the infrastructure is in poor condition and barely functional. For you, this translates to higher risks when traveling and less reliable roads and bridges.
Perché 45% di Stati Uniti. Bridges Require Urgent Repairs
Nearly half of NOI. bridges need immediate attention. As of 2019, 7.5% of highway bridges were classified as structurally deficient. Why is this happening? Here are some key reasons:
- Many bridges, built decades ago, can’t handle today’s extreme weather. Nearly 21,000 are at risk of flooding or foundation damage during storms.
- Heavy trucks, often exceeding 40 tons, are causing cracks and metal fatigue.
- Over 94,000 bridges are functionally obsolete, meaning they don’t meet modern traffic demands.
- A $125 billion repair backlog exists, with current funding falling short by 58%.
These issues make road safety a growing concern, especially for drivers like you who rely on these bridges daily.
Broader Impacts of Aging Infrastructure
When roads and bridges fail, the consequences ripple through every part of your life. Poor conditions increase accident risks, especially in areas with potholes, crepe, or weak structures. You might also face delays, deviazioni, and higher vehicle repair costs.
