We know in our heads that suspension bridges are flexible, but we don't normally see them put under so much stress that they have a visible bend. The weight limit on the one-lane Beaver Bridge in Beaver, Arkansas, is ten tons. The bus could easily be twice that, possibly several times that. You have to wonder what it feels like to ride that bus, and then you have to wonder what damage it's doing to the bridge over time. -via Digg
Update: The bus was 35 tons, and thanks to this video, the bridge is now closed for inspection. -Thanks, Christophe!
