“They don’t build ‘em like they used to,” as people love to say. That phrase could definitely be applicable to the 93 year old Broadway Bridge in Little Rock, Arkansas, that refused to fall even after it was lined with explosives. This certainly isn’t the first time a demolition has failed and it’s probably not the last.
Bridges are being demolished and replaced all across the country, due to America’s increase of failing infrastructure, which is leading to the development of some interesting time saving techniques in certain areas. After being deemed structurally deficient in 2010, plans began to replace the old Broadway Bridge and on September 28, 2016, the bridge was officially closed. On Tuesday, October 11, it was officially time for Little Rock residents to say goodbye to the trusted bridge, but they were given a few more hours than expected.
After structurally weakening the steel bridge, explosive were strategically placed throughout the structure. As the fireworks started, there were some cheers from the crowd, followed by plenty of laughs, as the smoke cleared and the bridge was still left standing. According to reports, the explanation given for the failure was that the bridge collapsed into itself. Nevertheless, the crews from Massman Construction had to get to work to make sure the bridge fell, as it could have been a major safety hazard. The crews brought in a crane to help nudge the structure into the water. 5 hours later, the structure had fallen and the deadline to clean up the bridge started.
The now demolished bridge is being replaced by a new one to connect downtown Little Rock to North Little Rock. Massman was awarded the project for $98.4 million, which was the low bid, but also resulted in the shortest schedule. The bridge will only be closed for a total of 6 months, even after initial estimates were 2 years.
You can watch 3 different videos of the demolitions below. The first, by Robert Cossio, shows the failed demolition. The second, by voigtlanderr2, shows the crane in the water forcing the structure to fall 5 hours later. The third, by Ben P, is a true test of endurance, as it’s the entire 5 hour live stream of the demolition process.
For almost 80 years, the Old Kosciuszko Bridge connected Brooklyn and Queens in New York. Much like many other bridges its age, it is being replaced due to capacity issues and deterioration. When it was completed in 1939, it was built for 10,000 cars per day. Unfortunately for the people who needed to use that bridge that past few decades, around 180,000 cars used it.
New demolition videos are always fun to watch. You know what’s even better, though? A bunch of demolitions all at once.
While being prepared for demolition, the Grand Avenue Bridge in Glenwood Springs, Colorado unexpectedly collapsed to the railroad tracks below. Thankfully, no injuries were reported, but the local police chief said that workers had to flee the scene once the bridge section started to fall.
Smoke stack demolitions are always fun to watch because they typically stand much taller than the buildings surrounding them, giving cameras great views of the carnage. They don’t always go well, like when a 2.6 million pound brick stack fell directly on top of an excavator (the operator was fine, by the way), but they’re always dramatic.
Buildings are demolished all the time in order to make way for new construction. The buildings that are demolished have usually lived out their useful life and are no longer functional. Recently a demolition video resurfaced, which shows a 27 story building in China being imploded. The strange thing is that, since it was finished in 1999, the building had never even been used.
A nearby office worker caught video of a dramatic demolition that showed the remains of an 11 story building collapse on top of the excavator performing the demolition.
In order to get the bad taste of last week’s botched demolition, in which an adjacent building also got destroyed in the process, we needed to share a highly successful one. Priestly Demolition, a Canadian demolition contractor, has been the subject of our articles in the past and the company has even won awards for the best demolition in the world.
Mistakes during demolitions happen. Sometimes contractors knock down the wrong buildings, other times the explosives used don’t knock the building over, and other demolitions are carried out with a complete lack of regard for human life. As fun as they are to perform and watch, they’re inherently dangerous and there should be a plan in place in case things go wrong.
Construction Junkie has shared a lot of demolition videos. Typically, people line up waiting for the moment when the building explodes with their eyes peeled and cameras ready, just waiting for the perfect video. This video, however, is much different.
Early this year, a landslide caused catastrophic failure to the Pfeiffer Canyon Bridge along California’s famous Highway 1. California Transit officials closed the bridge on February 21st and announced it would be demolished and replaced. Time is of the essence as US News reports that over 400 residents are stranded on one side of the bridge and helicopters have had to bring in food for them. The residents are still able to use the footpaths in the area to cross the canyon.
