Learning
from the past
The
August 2007 collapse of Minnesota's I-35W bridge over the Mississippi
River killed 13 people. Tragic as it was, that accident and what we learn from
it will help scientists and engineers foresee and act on structural problems
and prevent failures of other spans. In this slide show, see how lessons learned from past collapses have helped improve bridge
safety, and how "smart" sensing technology is already aiding the
monitoring and maintenance of bridges both new and old.—Rachel
