Key findings from the report released today by the nonprofit American Association of State Highway and Transportation Officials on the condition of America’s bridges. (This Friday will mark one year since the Minneapolis I-35W Bridge collapse that killed 13 people.)
- Age – Usually built to last 50 years, the average bridge in this country today is 43; almost 20 percent of these bridges are over 50 years old.
- Repair Costs – According to new data from the Federal Highway Administration, the cost to repair or modernize the country’s bridges is $140 billion, assuming all the bridges were fixed immediately.
- Traffic Congestion – The top 10 highway interchange bottlenecks cause an average of 1.5 million truck hours of delay each year.
- Construction Costs – The costs of steel, asphalt, concrete, and earthwork have risen by at least 50 percent in the past five years, forcing delays of bridge improvements and replacements. Nearly every state faces funding shortages that prevent them from the kind of on-going preventive maintenance, repair, and replacement needed to keep their bridges sound indefinitely.
