There are about two ways to bring down a structure: piece by piece or in a fiery blaze of destruction. The only problem with the second choice is that it’s typically followed by weeks, months, or even years of cleanup, but it makes for a great viewing experience.
The Saskatoon Traffic Bridge in, you guessed it, Saskatoon, Saskatchewan, Canada, stood mightily for 108 long years. The 951 foot (289.8 meters) long bridge connected Victoria Avenue to 3rd Avenue across the South Saskatchewan River. In 2010, the Saskatoon Traffic Bridge was closed due to severe corrosion and will be replaced by a newer and larger bridge by 2018.
On Sunday, January 10th, demolition of the old Saskatoon Bridge began with a bang, or, multiple bangs, rather. Two of the bridge’s spans were located directly above dry land, so they were subject to implosion. The final span, which sits over the river, will be demolished at a later time. As the explosions went off in unison, the two spans fell straight down to the ground and were quickly covered by a cloud of smoke.
The video below, by EpicJib Aerial Media, shows the full speed implosion and the slow motion implosion right afterwards.
Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
On Monday morning, a 13 story building in Miami Beach that was being prepped for demolition suddenly collapsed, injuring one Project Manager that was struck by debris.
In January of 2018, ten construction workers were killed and another eight were injured when a bridge spanning the Chirajara canyon in Columbia partially collapsed. That collapse has since been blamed on a poor design, reports have stated. Last week, the remaining sections of the bridge were demolished in dramatic fashion.
A couple weeks ago, we shared a list of the 100 tallest buildings to ever be demolished. One of the most interesting things that I learned while researching for that article was that although Detroit’s Greater Department Hudson Store was not the tallest building on the list (it was #21), it was the tallest on the list to actually be imploded.
In February, JP Morgan Chased announced their plans to demolish their current 52-story headquarters located in Manhattan. Turns out, when that demolition is complete, it will also break the record for the tallest building ever voluntarily demolished.
One thing’s for sure, the only thing better than one structure being demolished is two structures being demolished at the same time. Late last week, a decommissioned Florida Power Plant saw to the implosion of two 462 feet tall cooling towers in spectacular fashion.
Demolitions by implosion seems like the easiest way to knock down a structure, but there is so much preparation that goes into it that even the slightest mistake can have a huge impact. When smokestacks are demolished correctly, it can be a thing of beauty, like when these two silos in Scotland hit each other midair or when this asbestos filled stack was precisely demolished to fall into a pool of water. Things didn’t go so smoothly for demolition crews in Denmark last week, however.
