The speed and turbulence of an overflowing stream scours away the river bottom that provides the support for a bridge foundation, causing more than 60 percent of bridge failures in the United States in the last 30 years. Xiong "Bill" Yu, an assistant professor of civil engineering at the Case School of Engineering, has begun designing what he calls smart infrastructure — underwater sensors that relay real-time information about how much river bottom has been stripped away and how stable, or unstable, the supports of a bridge remain.
U.S. Transportation Secretary Ray LaHood announced more than $18.7 million in grants to 11 University Transportation Centers (UTCs) that are using new technologies and developing innovative approaches to improve transportation systems throughout the country.
Oct. 2, 2010, marked the official opening of a striking new landmark for the San Francisco Bay area — the Robert I. Schroder Overcrossing on Treat Boulevard in Contra Costa County.
As more and more bridges are declared structurally deficient or obsolete, there is a need for immediate and novel engineering solutions in order to be well prepared for potential disasters and minimize future maintenance costs. Bridges 2010, held in San Francisco, Nov. 16-17, equips its attendees with the information to prevent these disasters.
