Really bad backhoe (off topic)

A backhoe in Baltimore MD has set a new standard, and it was unmaned at the time. It seems while as flatbed was transporting a backhoe around the Baltimore Beltway (I-695), the backhoe hit a pedestrian bridge that spaned the road. The bridge collapsed onto the road, killing 1 person and sending 3 others to the hospital in critical condition.
