We here at Construction Junkie headquarters enjoy a good demolition video. We’ve shared implosion videos, timelapse videos, and even demolition fails, but since our inception, we have yet to share a wrecking ball demolition video. Growing up, I thought my adult life was going to be littered with wrecking balls (and anvils, for that matter), because of all the cartoons I watched, but as our industry’s heavy machinery and explosives have become more precise, the need for wrecking balls has slowly diminished.
BUT FEAR NOT, that all ends today, thanks to the city of Bath, Maine. The Route 1 viaduct, which has stood in Bath for about 59 years, has seen its final days and is in process of being torn down. It spans over 1,300 feet in total overtop of local Bath streets, carrying an average of 30,000 vehicles per day. Much to the chagrin of the residents who use the bridge or live near it, it will take nearly 8 months to tear the existing bridge down and replace it with the new one. That means 8 months of bad traffic and tons of noise. Officially, work began in May of 2016, but the viaduct remained open until October.
According to WSCH 6, the original bridge took 720 days to build, but contractors will only have 220 days to completely replace it. That’s a significant improvement but many DOTs around the country and cities around the world are embracing more pre-fabricated designs to greatly reduce the impact to traffic and local business. For instance, the Connecticut DOT found a way to reduce a 2 year bridge replacement down to 28 days of traffic interruption. That’s something I think we can all get behind, as working more offsite keeps workers much safer.
On Tuesday night, another portion of Route 1 was taken down by our old friend, the wrecking ball. In a video shared to Facebook by the Bath Police Department, you can see three powerful strikes to the already weakened section. I would hate to live near this area, but I love watching the video.
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.
