Building 10 MOVABLE Lego Bridges 

i like brick

this is a great demonstration. what I like is that you can fairly intuitively understand that these different mechanisms were invented to solve specific problems that the others don't address.

Nice bilfs!

And the video just ends right there. What a work of art. No asking for subs, likes, linking videos on screen to get additional views. It just ends with all the bridges on screen labeled. This is perfection.

I have no idea why, but the sound of the car going over the bridge each time is just... lovely?

I just love the fact you can build an entire successful youtube channel/career off making nerdy engineering stuff out of lego. Amazing.

Nice to see at #10 the transporter bridge receiving a bit of love. Just a handful of them still remains, much less in operating conditions, and I live just 5 km from Bizkaia Bridge, the first one ever made and still perfectly working at 130 years old, an UNESCO heritage monument. The Eiffel tower of bridges (seriously, Alberto Palacio, the engineer, was a student on Eiffel studio).

Bridges are definitely one of, if not, the most interesting pice of engineering. Combining bridges with lego, and doing in a simple way like this video, is just so cool

The sound of the legos clicking together is always so soothing. 😊

This feels like a chaotic version of Poly Bridges, and I’m all here for it

This is an amazing demonstration despite it being so small, he tried to make the design as compact as possible using lego as the base. This is just marvelous and an always iconic illustration of how you can put kids toys to real engineering.

Bridging the gap in bridge knowledge

The folding bridge looks the most unstable. I hope in real life, reinforcements are added so that it doesn't bend as much as this one did. Well done on this!

If there's ever a part 2, consider including the "Strauss Bascule." The most common design uses a parallelogram linkage and they are found all over Chicagoland (mostly for railroads), as well as lift bridges (7:15), Scherzers (1:21), and some old designs that are now locked in place including a Rall bridge, Page bridge, and bobtail swing bridges. There's a PDF called "Historic Chicago Railroad Bridges" that explains more about them.

Honestly despite how simple the video is, I must say it’s incredibly entertaining and satisfying to watch👍

I love seeing these in action. My city has a big swing bridge that lets all sorts of big and small ships pass through; seeing it on such a small scale as well is really interesting.

I wonder if it is possible to make a horrifying bridge that uses all of them.

I love how the ones that perform the best are the ones commonly used in real life.

4:22 was a certified Bridge Constructor moment…

i like brick. The sound of the legos clicking together is always so soothing. .

It's impressive how much you communicate without uttering a single word. The use of motors etc to show the mechanisms and minifigs moving on their own after building with your hands really brings the LEGO to life! Perfect video, as always.

You know its a good day when Brick Experiment drops a video

Loved this, I wish there were Technic sets that did this sort of thing. For a real challenge the Vazon sliding drawbridge in Lincolnshire, UK would be an amazing thing to model.

The synchronized but at the end was a plus. Great video demonstration.

It would be cool if you did a part 2 where you recreate some of the interesting draw bridges in the Netherlands!

5:00 Every day I row under one of these. The bridge is massive. You can see the gears working and it's just super cool.

As a pro castle builder, i see them all as an absolute win.

I built a retractable bridge style ramp for my 1/10th scale theme park ride (the thunderflash roller-coaster) only mine retracted under the platform instead of over and had a 2 step extension arm too. All inspired by your marvellous creations thanks bro and can't wait to see what you come up with next 👍.

This is like miniature IRL Polybridge 😂

My favorite one is the folding bridge, as that allows you to cover a massive space with a one-sided bridge! It could do with some extra locking mechanisms and reinforcements in reality, though, as no bridge should bend down under heavy loads as much as that one did.

yeah its fun to watch all those various ways to build bridges. i was interested in it before too. but honestly, the mechanisms between gears and all the mechanical parts really facinates me... like most of those are probably not advanced at all, but im not experienced with those - although i kinda wanna use it somewhere. nice video.

You must be an engineer! My favorite bridge was the first one. Plain and simple and gets the job done. I have never seen the clear gear box before. Going to have to search for it. Thank you for sharing.

5:10 seems like the driver fell in the water anyway. rip

4:10 This mechanism is similar to a cars convertible roof folding back. It would be very interesting if someone implemented it into a build! Very cool video!

Coolest LEGO TECHNIC MOC, I've ever seen..!! I love the use of the mini figs..

i love the end. The Screams of the lego motors, fills me with joy

A wise man once said _"perhaps the best Lego is the one we made along the way"_

I can't help but wonder, why would you pick one bridge over another? Where's the shots of something going wrong and a new bridge coming in that addresses that problem? I like seeing iterative design in action- or at least some pros and cons.

I like how the boat just yeets itself off the edge of the world right after sailing under a movable bridge

In the drawstring one it looks like you fed the string into the cylinders that propped the string up (whatever they are called), how did you do that? To better explain, during the calibration process where you held the string so that it could tighten, where did the excess go?

Final Products 1. Simple Bascule Bridge 0:42 2. Rolling Bascule Bridge 1:21 3. Drawbridge 2:13 4. Retractable Bridge 2:58 5. Folding Bridge 4:10 6. Swing Bridge 4:58 7. Tilt Bridge 5:38 8. Table Bridge (pneumatic) 6:22 9. Vertical-Lift Bridge 7:15 10. Transporter Bridge 8:29

My favourite part is seeing the boat falling down right after it passes the bridge as if there was a waterfall Edit: you can see all of the boat falling down at 8:55 and ut’s the funniest thing

Excellent modelling along with excellent detachability and flexibility with excellent to look simplicity behind concrete engineering

The vertical lift bridge is my favorite. It reminds me of the one in Duluth, MN. You should have shown that cars can be on the bridge during the lift. It give you a good view.

7:43 Transporter Bridge is a very unusual idea. Idk if you pay for the bridge or not but slow and delayed. Imagine if they keep using those ideas, it'll get traffic forever...

The joy I felt when I saw you did all bridges side by side synchronised!

The turning bridge is the most efficient, balance is spot on

7:24 I was waiting for you to lift the bridge with the car on it!

1:48 Medieval bridge! Cool Idea!

Polybridge tutorial Actually very interesting, it's awseome see how much possibilities there are with lego pieces 0w0

The best thing about LEGO is that it can be used to translate into real life, so most, if not all, of these bridge designs can and will work, and have worked, irl. LEGO is just simply too good.

Love these lego videos! My math teacher showed the class some of your videos which was cool!

As I was watching this I was thinking I'd love to see your take on a transporter bridge. Did not disappoint! :D There's one near me that's over 115 years old and is still in use today.

Pic your favorite bridges: 0:10 0:52 1:33 2:24 3:13 4:26 5:15 5:50 6:39 7:29

in my opinion the bascule bridge is the best, its fast and it seems very simple to build.

Very cool! I don't know if these all have real-world examples but if they do it would be cool to put a little clip of a real-life bridge with that mechanism after each one!

My favorite was definitely the table based purely on the fact that I didn’t know LEGO had produced pieces for pneumatic.

az első a legjobb.... egyszerű, olcsó, elegáns, fenntartható, a többi komplikálthoz képest...bár jobb egy olyan híd amit nem akadályoz senkit a haladásban és emelgetni se kell

WE used to have a swing bridge like #5 were I´m from. It was build in 1927 and replaced with a modern bridge in 2003 :) It was very cool

Never fails to impress me

Now we're gonna need RCE to review it

Love your videos. Always excited to see a new one posted

ASMR + Engineering + LEGO = Win.

Very fascinating. Would love to see how efficient each design is in energy usage.

0:08 A MAN HAS FALLEN INTO THE RIVER IN LEGO CITY!

I like the new textures of the Poly Bridge. XD

0:10 Bascule bridge (Simple) 0:51 Bascule bridge (Rolling) 1:33 Bascule bridge (Chain-attatched) 2:24 Retractable bridge (also known as Thrust bridge) 3:13 Folding bridge 4:26 Swing bridge 5:13 Tilt bridge 5:50 Table bridge (pneumatic) (similar to Vertical-lift bridge) 6:39 Vertical-lift bridge (hydraulic) (similar to Table bridge) 7:29 Transporter bridge (also known as ferry bridge or aerial transfer bridge) 8:49 SIDE BY SIDE 9:09 SIDE BY SIDE (synchronized)

Would be interesting if you made a video about movable bridges, as in: bridges you can place down and pick back up again after use!

Your a amazing lego engineer. Your intentions is like great. Awsome!

1,3&6 are my favourite ones and number 6 (4:58) is also nice for when you want to change roads

This guy is a lego engineering genius

When you realise you can just make the bridge taller but you’ve been trying to build this guys inventions for over 2 hours: BRUH…

I could see a combination of bridges. For example the addition of the Transporter bridge with others. Now a container ship could offload a container onto a bridge. And then a truck could transport the container on a highway. You wouldn't necessarily go to a standard port to unload your cargo. In fact there could be a combination of rail and truck for transport.

The table bridge got me a good laugh, well done xD

I like how this youtube channel is constantly teaching us mostly simple logical solutions to modern mechanisms. Very informative and makes us more aware of our surroundings.

This is why both a ship to battle against another kingdom and a vehicle going to McDonalds are *able* to *safely* cross the bridge. The battleship just won against Brickish Kingdom. The vehicle went to McDonalds and *finally* found the normal ice cream machine and bought what they want. Nice build!

Some improvements could include tension pulleys when string is used, wheels instead of smooth bricks for the transporter bridge and retractable bridge, second guide for the retractable bridge, and many more. But nicely done in its simplest form of demonstration. 🙂

I smile when the truck rolls through. It’s like “Twelve Days of Christmas “, “and a partridge in a pear tree!” 🎶

imagine the transporter bridge (7:29) irl😂

I like the last bridge and the truck used to cross the bridges

If you wanted to be a bit more compact on the folding bridge tou could use 2 gears and a chain instead of 3 larger gears

5:40 bro just rides through a cable lol

Bro imagine what would happen if a car was there while it was going up😂 5:26

You have the greatest satisfying videos on RU-vid! Thank you!

What a great video, thanks a lot for these ideas. I will for sure rebuild the one or the other... 👍🏼😀

Very cool!!

Great video. The more complex something is and the more parts used, the higher the chance of something failing. Keep things as simple as possible, for longevity. Applies to everything

My favourite part is seeing the boat clearly fall over some edge just as it's going off screen.

Please consider treating us with a video of more involved versions of these simple beauties next. I happily watched this'un again straight after it first finished. You've concentrated on the deck here, how about the supports in the next one? Then you could have Suspension, Cable Stay and - what I'm really hoping to push you towards (phrasing!! sorry) is your elegant version of Tower Bridge on the Thames with its Double Bascules and seemingly Suspension cables and yet Box Girder too. Many smiling thanks for being such a brick.

8:21 next, make a lego 3D printer

3:05 retractable bridge design flaw you need to make the other bridge a bit lower, and add a smooth piece so the bridge doesn’t click onto the other side

The Slauerhoffbrug is a cool one to make from LEGO. A bascule bridge where the pivot point is moved to the side of the road. Also, the typical Dutch drawbridge is missing!

Could you do a video for types of tidal control gates?

I'm kind of curious how you would approach a bridge with a railway over it. You could use the vertical lift bridge, but the gap would be an issue. If you'd like to build more bridges, could you consider approaching one with rails on it?

3:45 I am enjoying the sounds of the womb.

The ideas are really great. It was so clever that it felt good to watch.

The swing bridge definitely my favorite.

anyone else gettig polly bridge vibes here

0:44 who else saw small plastic rope

Don't know why but I think I've watched this video for the 10th time, but I still want to watch it again, it's so amazing and interesting
