I was amazed no one had posted about this already, but there was a major bridge that collapsed in Minnesota this week. I never assume that people in other states or other countries know about it since I live there, but it has gotten a lot of national and international coverage. The bridge was a truss bridge which means that there isn't anything in the holding the bridge up in the water, but it is on the land part of the bridge.Has anyone seen many bridges like that out there?
