The view has shifted the past few years during Ken Holmes’ daily walks along the Ohio River, and on Tuesday, it changed yet again.
Until 2016, emissions from two smokestacks often billowed above Neville Island near Pittsburgh. When the Shenango Coke Works shut down, its stacks still dominated the landscape. But just before noon on Tuesday, they disappeared forever.
A series of planned dynamite blasts sent the stacks, plus a coal bunker, crumbling to the ground.
