Robert Peterman, KSU Structural Engineering Professor:
"Structures have a certain life and typically that's been about 30-40 years for a bridge structure.
What we're able to do with new materials is go in and take an existing structure
that's in need of replacement and we can, if we apply some new materials and
new repair methods, we can extend the life of that structure out another 20-25
years. On the new materials side, as we look in the new materials to put in
the bridge, we're now talking about making a bridge last - there's talk now going
up to 100 years."
