Florida International University (FIU) researchers are developing innovative methods to diagnose and repair aging bridges using trained dogs, advanced concrete, and MRI-like technology. This initiative aims to enhance the safety and longevity of the approximately 620,000 bridges in the U.S., particularly benefiting the 13,000 in Florida.
- 01FIU leads a collaboration of seven universities funded by the U.S. Department of Transportation to address bridge infrastructure issues.
- 02Trained dogs, Loki and Pixie, have demonstrated a 98.7% accuracy rate in detecting corrosion through concrete.
- 03The Magnetic Flux Leakage device can identify corrosion in steel cables, crucial for bridge stability.
- 04Sprayable Ultra High-Performance Concrete (UHPC) offers over five times the strength of conventional concrete and allows for quick repairs without shutting down bridges.
- 05FIU's research is positioning its students as leaders in the field of infrastructure technology.

Researchers at Florida International University (FIU) are pioneering methods to diagnose and repair deteriorating bridges, utilizing a combination of trained dogs, advanced materials, and technology. This initiative, part of a collaboration among seven universities funded by the U.S. Department of Transportation, aims to address the urgent need for infrastructure improvements across the country, particularly for the 620,000 bridges in the U.S., including 13,000 in Florida. The project showcases two dogs trained to detect corrosion, achieving a remarkable 98.7% success rate in blind tests. Additionally, the team employs a Magnetic Flux Leakage device, which functions like an MRI to identify corrosion in steel cables that are vital for bridge integrity. The introduction of Sprayable Ultra High-Performance Concrete (UHPC) allows for repairs without the need for extensive closures, significantly enhancing repair efficiency. FIU's efforts are not only advancing bridge safety but also preparing its students for future challenges in infrastructure management.
