More than 100 years of history came crashing down this morning in Lawrence, Massachusetts, two smokestacks at 290 Merrimack Street were imploded this morning.

The demolition is part of a new reality program profiling the lives of Lisa Kelly and her husband, Eric, who run Idaho-based Advanced Explosives Demolition Inc. Cable network channel TLC was filming the event.

The smokestacks are coming down as part of Sal Lupoli's Riverwalk revitalization project.

Lupoli initially wanted to preserve the smokestacks, like he did with two others down the street, closer to the highway. But these two smokestacks, attached to the old boiler plant that provided power to the neighboring century-old Wood Mill, are structurally unsound.
