Building safer bridges

Across the country and around the world, structural engineers are planting sensors inside concrete so they can tell when a bridge, office tower, and other tall structure is in danger of collapse. One prominent example of where this technology is being used is the St. Anthony Falls Bridge (I-35W) in Minnesota, which collapsed in August 2007, killing 13 people and injuring 145 more. It's too bad it takes such a tragedy to find ways to prevent them from happening again, but kudos to those who have embraced the increased safety measures.

Has your firm used these sensors? Will it be trying them out?
