New Sharon Bridge Eventually Collapses After Explosion Fails



New Sharon Bridge Demolition



” A century-old bridge came crashing down just after 5 p.m. Thursday, three hours after an initial blast of explosives failed to collapse the structure into the Sandy River and an excavator had to finish the job.

  But when the truss eventually fell into the water, it landed upright instead of on its side as the contractor had anticipated.

“ It just collapsed perfectly,” said Project Manager Andy McPherson, of CPM Constructors. “It went straight down so we can actually use the bridge itself to get into the water.”

  McPherson said the explosive charges initially did not knock the bridge down as planned because the company did not know about steel beams in the abutments, which were not listed in the bridge plans.”
