Very impressive! After crossing this bridge 100's upon 100's of times, the demolition of it with the expertise of PDI brings closure to a unique part of Northern Ontario history ! Well done and congrats!
On January 10, 2016, the new bridge was closed to traffic after all 40 M22 (7⁄8 in) bolts attaching a main deck girder to the northwest bearing failed during a winter storm, causing the deck to lift by 60 centimetres (24 in), resulting in the indefinite closure of the Trans-Canada Highway at the bridge.
I wish I lived in Canada so I could work with your company, you guys do have fantastic operator's and you provide them with everything needed to do the job right. Nothing but the best equipment. Huge company with the small family business that is hard to find anymore
Good job done guys !!! Work like that makes you sleep good at night and also being outside does the mind and body wonders. Be safe and vigilant. Thanks again from Connecticut USA
I was driving through Northern Ontario and had no idea this bridge was there. Tearassing through the wilderness, nothing but trees and highway for hours and hours UNTIL THIS AMAZING BRIDGE hoved into view. I was awestruck--I couldn't help but slow down and just gush about how amazing and unexpected this bridge was! It is seriously an impressive piece of engineering, made all the more impressive by the wildness and ruggedness of the area it's in. Big props to everybody who worked on this thing--you guys did great.
Its not the original bridge. it was a second one. The first one was replace in the 70s i belive. I used to live about a 5 mins from the bridge. And had the oportunity to work on the project. Not this project. But the builiding of the new bridge. Got to help Presly build roads to reach the bottom of the peirs.
I watched these guys take over 45 minutes to warm up machines due to the cold. Hoses and fittings blow off like nothing in that cold. I even witnessed them change out the Hydrolic oil for Canola oil because of the enviromental sensativity of the job with the river being a nature reserve for fish. Was an amazing project to be a part of. But the original bridge was actually demolished around the 70s and was replaced with the one in the video. I lived about a 5 minute walk from the bridge. I seen peirs from a bridge long before the one in the video. Im having trouble finding the history since the new one is now so popular. Preisly demolition did an amazing job on this removal. They truly cared about the envormental impact that there demolition could pose and took more then enough messures to insure it was done to the properly.
I remeber when i worked in Ontario for 4 years in construction . Those demolishion guys know their work and they are really efficient in everything that they do .and will get the job done in record times . Unlike what we see in Quebec even today and the construction companies in Ontario are way more efficient to compared to Quebec and their work has even more quality to
Excellent video. Only problem is the blueprints constantly used for infographics were from the original 1937 structure, which was fully replaced in 1974 by the bridge that was actually removed in this video.
There in Nipagon was but one stoplight T highway intersection, where back in the 90s, the two Canadian highways merged into a single highway westbound! Then Nipagon had the only main highway intersection between all of eastern and western Canada! Good to know they have built the new bridge! More moose than people there, maybe except in Thunder Bay!!
I think PDI must have read Pierre Burtons book "The last spike." They ( CP) builded that railway bridge right next to it the sameway in reverse. they didn t have the tools of today. The bridge is still there, the trains are still rolling over it. that was also an great engeneering work.That was build more then 125 y ago approx.
23:32 Correction the original steel deck truss road bridge built in 1937, which is seen at 2:01 of the video was removed in 1974. Priestly removed the the steel plate girder bridge which replaced the original bridge. The new cable-stayed bridge is now the 3rd reintegration of the Nipigon River Bridge. Also, are you sure you don't mean Yanny @15:45 XD
Do you guys spend as much time on videography as demolition? Awesome video, awesome demolitions. You guys are skilled, both at demolition and at videography. An unusual combination, but it's pretty badass.
I wish the crews would work in the winter here in the US, if they did roads like I-76 in PA would finally have the construction complete, its been under construction for almost 20+ years..
I like it when a good plan of attack come together and everything works well as it did here. what kind of clothing did the worker wear for the -40 weather?. Thanks for an outstanding video. (Mississippi gulf coast, USA)
Incredible engineering, however script states 246 meters long but narrator states 252 meters, so is the 6 meter discrepancy to allow for shrinkage and expansion due to weather?
No bridge expands/contracts that much. The coefficient of thermal expansion for steel is about 9 x 10^-6 metres per metre per degC. For a temperature range of -40 to +35, a bridge span of 246 metres would expand about 160mm.
Awesome collaboration! It's too bad the new bridge failed so badly. Guess the powers that be should've just fixed the old one.... Thanks for the video.
@@63256325N Boy did that cause havoc in the heavy haul industry. We had to postpone or go through US. Customers don't want to pay more, and the contractor won't pay so postponing usually was the only solution.
@@63256325N More than a few bolts- bad engineering from the start. And yes- all 4 lanes opened Nov 25, 2018. 3 YEARS after the fuck-up. A total disgrace to all involved.
They needed to double the traffic capacity of the old bridge, huh? Why not just double it up with a second one beside it? 2 lanes each way, Bob's your uncle! Not as much opportunity for graft, though! - too cheap!
Because all bridges have a lifespan and this one was at the end of its life. Why repair an obsolete bridge when building a new 4 lane is cheaper than building a new two lane and sinking money into the old bridge.
And then a pigeon landed on the end of the carefully balanced bridge and the whole thing landed in the river. Oh wait that's what I was hoping happened
yes what a disaster this bridge has been nothing but huge problems from day one, with our cold weather and dumb engineers that dont have any common sense the bridge lifted off its gritter over 3 feet in the air, then instead of correcting the problem they load the bridge road way with hundreds of thousand of tons of concrete to weigh it down to set it back down, this ended in lane closers for months, it been one thing after another again this summer lanes been closed for weeks into months, what a joke, not a bridge for this area ant thousand contested it that it will not work, and here in Oct 2018 still always huge problems and traffic stalled, this waste of money one day will have to be removed and a proper bridge put in,,, .. you should see how high that bridge keeps lifting off the road
Yes...and unlike what the video says the old bridge was actually from 1974. My question is why they didn't just build a new bridge next to the existing bridge then just use both? Sounds like a tremendous waste of money to me. I don't live in Ontario, but I can imagine the same amount of waste has happened all across the province...no wonder the old government suffered that terrible defeat!!... :-)
@@FreewayInterstate yes a huge waste of money i will bet due to all the problems and every time we turn around the bridge is closed, it keeps lifting off the road 2 to 4 feet and they load it down with weights until the weather warm up,, well that tells me the cables are way to tight, but the dumb ass running it has no clue, if this bridge ever got taken out it cut off everything to the east and west totally, i have lived here all my life, no other way around but old logging roads and not passable with anything but 4x4 an ATV

I don't know. I'm guessing less than fifty years. And will probably be replaced with a bridge similar to the one that was there before (but four lanes).
@@FreewayInterstate Wouldn't it make sense to build modular bridges that use stock deck sections that can be easily replaced. Why build every bridge as a one of a kind structure? The sections could be made offsite and replaced in a day or two instead of taking months.

old one is past due, and too costly to maintain and update to current safety standards for vehicular traffic.
