In just seconds, the power plant is reduced to rubble.
The 464-foot-tall cooling towers at the St. Johns Power Park in North Jacksonville were imploded Saturday.
To prepare for the implosion, Total Wrecking & Environmental LLC used hammer drills to bore 3,800 holes for explosives.
The areas of the shell where explosives will be loaded on the inside were covered with chain link fence and geotextile fabric covers the outside.
The holes were loaded with a total of 1,500 pounds of dynamite and wired with more than 12,000 feet of detonation cord and 3,800 blasting caps.
