With more than a thousand of the workers who helped build it looking on, U.S. Transportation Secretary Ray LaHood dedicated the “Mike O’Callaghan-Pat Tillman Memorial Bridge” at the Hoover Dam. When it opens to traffic the week of Oct. 18, it will become the western hemisphere’s longest single-span concrete arch bridge and one of the tallest in the world.

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.
