The demolition of the 94-year-old Greenfield Bridge happened Monday morning, WPXI reported.
After years of planning, the implosion destroyed the bridge in seconds, shattering pieces onto the Parkway East.
The Parkway East will remain closed for several days, impacting thousands of people who use the roadway, WPXI said.
“We’re hopeful that the Parkway can reopen sooner than New Year’s Day. We’ll see what happens,” Pat Hassett of the Department of Public Works told WPXI.
People within the blast zone were not forced to evacuate and no drones were allowed in the restricted airspace at the time of the implosion.
