The construction of the Gordie Howe International Bridge is a major infrastructure project spanning both the United States and Canada. The bridge is named after Gordie Howe, a Canadian ice hockey player who was one of the greatest players in the history of the sport.
The project involves a significant workforce, including engineers, construction workers, project managers, environmental specialists, and various other professionals. These workers come from both sides of the border and collaborate to ensure the successful completion of the bridge.

Another awesome video Michael. These have to be the best videos on RUclips thanks. The crane operator and all the bridge builder's are the best 👍👍👍👍👍👍👍👍👍.
That's very kind of you Robert! Thank you!
WOW - Absolutely Amazing - These workers really know what they are doing - and Everyone seems to be so SAFETY CONSCIOUS.
Well, apart from at 2:26 when the guy in orange at the bottom of the mobile scaffolding shifts it to one side while the guy in green balanced on the top of it almost falls off ... and then seems to give the guy below a bit of an earful.
@@dougall1687 yeah that was pretty shaky.
Safety conscious- duaaa
@@dougall1687 Sharp eye!
Be careful everyone; no one is allowed to get hurt on this project - Canada/USA - best friends on the planet...NO INJURIES...everyone goes home safe. GREAT project.
Well said!
Wow! That crane operator has amazing skills!
Those huge cranes just mesmerize me. The best of the best, those operators ⭐
So nice to see how easily the bolts just slid right in, accuracy plus!!!
Nine buckets of bolts on the beam, Hanging in the air, workin the livin dream. Nice flying too. 🇨🇦🤙
That would be a cool job.
I bet those guys sleep well at night! Hard work 💪. Thanks for posting and keep 'em coming!
I bet they do too. Thanks for watching!
Son was in town 3 weeks ago to visit, took him for a ride to see the construction, he was impressed. Drove under it on the American side.
It's something to see. Thanks for watching!
Those crane operators are going to be millionaires after the project but it's worth it they sure do a great job
They deserve the money.
The person operating the crane doesn't get paid enough!!! !!!😊
Oh he gets paid enough!
He pension will be great too, he earnns it every day!
Now think of the operator in the tall tower crane, who gets to just watch most of the action from up high, and yes, they earn it too!
Proof that there is great honour and dignity in work !!
Yes, it still exist.
These workers are awesome what accomplishment
final Canadian and American edge beams are going in we are now down to 20 feet.
One Humungous Lego set😂
My thought, too.
Glad to see all the safety harnesses used today. I have observed that this is not always the case.
It's much safer now days. Thank you for watching!
Awesome videos
Just amazing
What is the size and quantity of bolts required just to make up each end of the main outside beam connection? Very impressive footage of the construction.
I like the row of buckets along the girder, I guess for the few hundred bolts.
Thanks for watching!
So cool
Very nice. Thanks for sharing.
Thanks for watching!
looks like the ironworker on the scaffold did not know his placement was bad and someone was going to move it for him!
Looks a little unsafe.
Don’t spill those buckets of blots and nuts.😃
I'm surprised they let you get that close with the Drone
They must like me.
When we first started using drones to document progress we had to use them after the site was down. It was too distracting to the workers. Now drones are all over and most folks never notice.
@@bobhall4588 That may be true but when they are working hundreds of feet in the air respecting their privacy and not providing even the smallest distraction should be the first priority. Drones are electronic device and there are many videos of them doing their own thing. It would be terrible if a malfunction happened and caused injury to one of the workers.
I would be interested to see a chart of the loads, with margins, on the suspension cables. As more edge girders are added, the angle of the stays becomes more acute, increasing the load, as more of the force is in compression (toward the tower) in order to maintain the same level of suspension. And will the stays continue all the way to where the bridge is joined in the middle, or will longer “bridge” girders be used to fill the gap ?
As I understand it, there is one more set of edge girders and cross beams to go on each side (15 meters length) and one more pair of stays attached to each. Then they'll add a single piece in the middle. At this point, I'm sure they know exactly what the dimensions of that piece will be. I'd love to know where that's being manufactured and how far along they are in getting it ready for installation.
@@PaulLaginess Would that center piece have to be some kind of slip joint to allow for 120 degree temp differences of the steel. And earth movement of the towers over time. North america is still rising, and distant earthquakes. New Mardrid Fault. Charleston fault.
The compression is vertical on the tower from both the over land and over water spans. They are in balance to avoid a horizontal load on the tower. It's a big swing with an anchor point at the back of both over land spans. The middle section is just a wedge to transfer wave loads of moving traffic between those two points. Charts and loads are moot. The purpose is to balance them with an engineered range based on respective material strengths.
Quá tyệt vời.❤❤❤
How about shooting a video of the cable stay placement?
Great work stay safe
Thank yo for watching!
Its amazing does anyone know if those bolts have double nuts on it
I'm pretty sure Canada doesn't want their bridge to fall, they've put a lot of effort into it, and they are hoping it will aid their economy. That noise in the back ground is like something you'd find on NPR 0600 hours on Sat and Sun mornings.
Probably and I would bet that the last nut is welded to the bolt to prevent it from coming loose once they tighten it.
Probably a pre applied locktite of some sort.
Vin: I doubt it very much. The bolts are tightened such that the stress in the plastic range. They will not loosen due to vibration. Having said that, it is absolutely imperative that all bolts are properly tightened as proscribed by the Canadian Handbook of Steel Construction. Not doing so will cause the joint and bolts to fail in fatigue.
Structural bolted joints have now been in use for 90 years or so and I know of only 1 instance where a joint failed in fatigue. This was caused by improper tightening of the respective bolts.
One of those connectors will be first to cross! Lucky him.
Thanks for watching!
As a licensed drone pilot, awesome video. Great flying and perfect choice of music. I am now a new subscriber of this stunning video. May I ask the name of song and artist of this music in this video?
Thank you for subscribing to the channel! The music credits are in the description.
How long is each one of those girders?
👍👍👍👍👍
There so close when do they expect contact
Unions build this country 🇺🇸!
Union workers NOT unions!
What is the length of the beam?
They're all 15 meters.
At this point probably 65 to 85 feet. The beams get shorter as you near the middle, and I am just guessing there. It still weighed 90,000 pounds, and that is at least a 60 inch beam. Pretty cool to watch them install it.
@@dangroat4438 You could vary the length of the beams and use the same strength cables, or, the same length beams and increase the cable strength as you went out.
Saftey harnesses
better
5:30 Safety harness or not. Standing on a wobbly ass scaffold several hundered feet above a river is not for the faint of heart.
And on a windy day too.
Swinging a sledge. Could've used a little more bracing.
Amazing how fast these union workers work when there’s a drone overlooking there every move! Should have a drone on them all the time maybe the bridge would finish on time and on budget???
You are ignorant
Hopefully there's no way a ship can strike the bridge.
No way.
Last section?
Not yet.
Don't tighten too tight...just hand tighten please....just my opinion.

This video is really instructive. Is it appropriate to ask technical questions? If so, two questions keep returning to my mind from video to video: 1.To the untrained eye, there appear to be many holes, close to each other, in the short and thin overlapping steel sections that hold the girders together; don't these holes weaken these sections? 2. Could someone indicate if there is a video that shows how the 2 meter long (or so) white tubes on the girders, where the suspension cables are inserted, how these tubes are affixed to the girder? I see many indents/holes/rivets in the other side of the wall of the girder that seem to correspond to the location of the tube. Again, to the untrained eye this installation seems superficial, mostly attached only to the wall of the girder and not to a reinforced section. Could someone provide details?
bad: I can give you a partial answer. The total thickness of the splice plates is equal to or slightly greater than the beam member (vertical = web, horizontal = flange) being spliced. The design engineer makes allowance for all the bolt holes in the beam members and splice plates so that the allowable stresses are not exceeded. The Canadian Handbook of Steel Construction has rules and guide lines for this type of design.
The stay cable attachments are a bit of a puzzle. A detail drawing of this item would be interesting. One way of doing this would be to make the attachment tubes a high quality steel casting, with the attachment holes drilled and tapped (threaded) into this casting. But I really don't know how it is done on this job. A heavy weldment would be another way, perhaps utilizing submerged arc or electroslag welding to join the pieces. The final piece is then bolted to the edge beam.
@@BasementEngineer Thank you for your concise and ponderate answers.
