Bridge in a Backpack Gets Notice 

U.S. Transportation Secretary Ray LaHood will be at the University of Maine Monday to check out a new process that could cut the time and money it takes to build bridges. Researchers with the University’s Advanced Structures and Composites Center have designed the so-called “bridge in a backpack”.It features a carbon fiber fabric that’s unfolded, inflated, and coated with a resin at the job site, then filled with concrete.Habib Dagher, with the center, says the bridges are faster and cheaper to build, and last longer than conventional bridges.
