Bridge Inspection

Posted April 24, 2018, Length: 21:12

The integrity of our infrastructure can be critical to life safety. Nowhere is this more obvious than our bridges. There are over 600,000 highway bridges in the United States, as well as a large number of transit, railroad, and pedestrian structures. Having timely and objective knowledge of the condition of these bridges is essential to assure their safety and efficiency. That knowledge comes from a program of systematic bridge inspections.

To help us understand the responsibilities and processes of bridge inspection, we’re talking with Dr. Sreenivas Alampalli, who is Director of the Structures Evaluation Services Bureau of the New York State Department of Transportation.
