A blast brought down the Commercial Street Bridge on Pittsburgh's Parkway East on Thursday morning, leaving behind nothing but a cloud of dust and pile of rubble.
Crews detonated the explosives around 8 a.m. on Thursday, demolishing the bridge. The implosion had been scheduled for Wednesday, but PennDOT pushed it back because crews ran out of daylight to make sure everything was safe.
Part of the Parkway East between the Squirrel Hill Tunnel and Edgewood/Swissvale exit has been closed since July 10. During the closure, crews will slide the new bridge, which has been built alongside the old one, into place.
The Parkway East is scheduled to reopen on Aug. 3, though that date could change.
You can see photos of before, during and after the demolition below.

"It was really cool," onlooker Kevin Lynch said. "It happened much quicker than you thought. You kind of heard the boom, you saw the smoke, and boom, it was gone. It was really different though."
