“The bridge that failed in Minnesota was only 40 years old. That’s nowhere near the life expectancy of a modern bridge, particularly one constructed as part of the nation’s Interstate highway system. The bridge carried an average of 140,000 vehicles a day. Each one of those vehicles, including trucks that carry higher loads now than they did in 1967, causes impact and cyclic loading of the pavements and bridge structure. Is there a problem? Of course there is. A recent report by the American Society of Engineers (ASCE) indicated that in 2003, the percentage of the nation's 600,000 bridges rated structurally deficient or functionally obsolete was 27.1 percent. ASCE estimates costs at $9.4 billion a year for 20 years to eliminate bridge deficiencies. My solution: Use networks of wireless sensors on bridges, giving engineers the chance to make bridges smarter."
Nelson numbers among the world’s geotechnical engineering experts and is the author of more than 120 technical and scientific publications. She is a former senior executive at the National Science Foundation (NSF) and a former University of Texas at Austin professor. She received her doctorate in geotechnical engineering from Cornell University, master’s degrees in engineering from University of Oklahoma and in geology from Indiana University, and a bachelor’s degree from the University of Rochester.
Civil Engineer: John Schuring
“This tragic incident is symptomatic of a looming problem in our nation, that of dealing with an ever-crumbling infrastructure. Unfortunately, the rate of deterioration appears to be exceeding the rate at which we are repairing or replacing things. This applies not only to bridges, but also highways, pipelines, power grids, and yes, even levees. As a nation, we really need to place a higher political priority on infrastructure and then make the needed investment to assure public safety and our quality of life.”
Schuring, a professor in the department of civil engineering at NJIT, is an expert in civil infrastructure and has experience with load testing steel truss bridges. He has worked as an engineer for the U.S. Environmental Protection Agency, the U.S. Department of Energy and the New Jersey Department of Transportation. He is a member of the American Society of Civil Engineers; a member of engineering honor society Tau Beta Pi; and a member of the New York Academy of Science. Schuring received his doctorate and bachelor’s degree in geotechnical engineering from Stevens Institute of Technology and his master’s degree in the same field from the University of Alaska.
