In wake of the fatal Aug. 1, 2007, Minneapolis , MN , Interstate 35 bridge collapse , after recovery efforts are complete, investigations will commence about the tragedy. Preliminary reports suggest that the bridge recently passed inspection, which may raise questions about engineering methods used for such inspections.

Engineering technologies helpful for structural testing include instrumentation and sensors that measure, record, and analyze corrosion, vibration, load, and metal stress and fatigue; wireless technologies that can help relay such data and information; and simulation software that can combine sensor input, design information, and historical data to help predict time to failure.
