Demolition videos are always fun, especially when it comes complete with a big splash and some waves. The Old Hulton Bridge, a 107 year old structure that connected Pittsburgh, PA suburbs Oakmont and Harmarville across the Alleghany River, went out with a splash, as it was imploded and landed into the river below.
The New Hulton Bridge, the old one’s replacement, has already completed construction and the demolition was the final piece to that project. The new bridge was constructed only feet away from the old, making a precise demolition even more important. PennDOT Executive Dan Cessna told the local CBS news station that imploding the bridge was the plan all along, and they factored that into the design of the new bridge. No structural damage was found on the new bridge, only scratches in the paint from shrapnel and the new bridge reopened within an hour.
150 pounds of dynamite and 51 charges in total were needed to bring down the old 2 lane bridge. Crews set up a 1,000 foot safety radius until just shortly after the implosion was complete.

When you need to demolish a building in a tight downtown setting, you make sure to hire people who have the right experience to do the job. Controlled Demolition, Inc (CDI), was at it again recently, when they shared a video of a recent building implosion in Dallas, TX.
Last July, a 13 story building in Miami Beach that undergoing a demolition suddenly fell, amid odd circumstances, and flying debris fatally injured one of the contractor’s project managers. Now, the family of the man killed is filing lawsuits against all parties involved with the demolition, calling it “illegal” and “reckless.”
Demolitions by implosion can be fun to watch when they go right – or wrong – but nearby residents can be greatly affected by the high powered blasts and huge clouds of debris that follow. A few years ago, a botched demolition in England left dozens of nearby residents unable to return to their homes for several days. Last week, an obsolete Steel Basic Oxygen Plant in Weirton, West Virginia is leaving residents in a similar situation.
JPMorgan Chase announced their intentions to tear down their existing 52-story headquarters in Manhattan, New York City early last year. When the demolition is complete, it is widely believed that it will be the tallest building ever to be voluntarily demolished. It’s speculated that the building will be dismantled floor-by-floor, as opposed to imploded, due to obvious safety concerns.
As you may already know, the NBA’s Milwaukee Bucks officially opened their new home, the Fiserv Forum, for the 2018-2019 NBA season last October. That new stadium is being heralded as the “World’s First Bird Friendly Arena,” due to many of the design features. Well, since the new one is open, we can only expect that the old, non-bird friendly (I’m assuming) arena has overstayed its welcome and has to go.
Let’s get 2019 started with the first building demolition by implosion of the year.
Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
