SADIEVILLE, Ky. (AP) - University of Kentucky engineers are
experimenting on a small country bridge in central Kentucky with
hopes of finding an easier and more affordable way to patch up many
of the nation's aging steel bridges.
The researchers were working Wednesday to reinforce a small
one-lane bridge that goes over a creek in Scott County. Instead of
steel beams, they were using thin carbon laminate strips that they
say can guarantee three times the load at a fraction of the cost.
The project is one of several authorized by the Federal Highway
Administration in recent years.
Civil engineering professor Issam Harik said this is the first
steel bridge in the U.S. reinforced this way. It was previously
tried in 2008 in Japan.
