The piers of the old Cohoes-Waterford bridge were loaded with 3,400 pounds of dynamite and then contractors hit the switch Thursday morning.
The state Department of Transportation has been taking apart the 1932 bridge since it opened the new one in July. The six piers were last to go. They were wrapped in chain link and a protective material to contain the debris. DOT says this was more cost effective than using machinery to break up the pillars.
"The idea really was the fracture them, to break them apart, not to explode them down to the river bed so to speak," said Bryan Viggiani, DOT Communications.
Now crews will scoop the chunks and crust of concrete and rebar out of the Mohawk. DOT says this was more cost effective and better than trying to break apart the piers with machinery.
The entire project costs about $21.5 million. The demolition of the old bridge costs about 1.6 million dollars.
More than 16,000 cars use the Cohoes Waterford Bridge every day.
The project isn't expected to be finished until ealy 2018.
