200 pounds of explosives take down bridge

Above is video footage of a 60-year old bridge being demolished over the Allegheny River near Pittsburgh last week.

It took 200 pounds of explosives to take down, and brought traffic in the area to a halt for around half an hour. In it's place two new bridges are being constructed to hold traffic, one of which is already operational.

The clear up operation will involve removing the fallen sections from the river, but also deconstruction of the remaining bridge sections connected to land.
