These REAL BRIDGES push my engineering skills in Poly Bridge 3! 

can you build a bridge between my parents so they love each other again

My grandpa is a civil engineer and he made the plans for the foundations for both the Storebælt bridge and Öresund bridge - it's nice to see you remake them in Polybridge and explain how they work :D Your pronunciation was surprisingly good btw! Only thing is "Broen" = "The bridge" so you basically called it the Green belt bridge bridge lol...

I am a long-time Portuguese subscriber that started to appreciate the beauty of our bridges thanks to your content, so it's extremely gratifying to see you build the gorgeous Dom Luís I Bridge! Thank you RCE!

I was a bit confused by the "GREEN Belt Bridge" - it's actually the Great Belt Bridge. I crossed it last year and its pretty scary when you do that for the first time, especially when it's windy and dark. These 6km really felt like an eternity. But it looks really impressive!

For any math nerds wondering, the curve, that a cable between two anchors falls is called a catenary curve (it's function is cosh(x)), which sort of looks like a parabola but is actually an exponential.

You actually did ok with the pronunciation of Storebæltsbroen. But alas, you said the english name wrong. It's not the Green Belt Bridge, its the Great Belt Bridge. Very accurate recreation, used to drive over that thing twice a week for a few years. Thumbs up.

I used to live right beside the forth rail bridge. You kinda get used to it as a kid, but it really is impressive to see up close. It's massive and it's still cool to go over on the way to Edinburgh.

With the way the road was responding to the cables not starting in the catenary shape, that last bridge reminded me a little of Galloping Gertie, the first Tacoma Narrows bridge.

The "Harbor Bridge" in South Texas gets a lot of love from locals. It would be awesome to see you recreate it in this game.

itd be fun to see how polybridge handles the world's shortest suspension bridge, literally called the Wiggly Bridge, in York, Maine

Greetings from Brazil mate! Here are some famous Brazilian bridges to add to the wheel: - Ponte (bridge) Octávio Frias de Oliveira - Ponte Juscelino Kubitschek - Ponte Hercílio Cruz - And the most famous (but least interesting) Ponte Rio-Niteroi Hope you see this! These vids are awesome!

As a Belgian, I'll choose 2 bridges not in Belgium: - Grand Duchess Charlotte Bridge (aka Red Bridge) in Luxembourg, capital of Luxembourg. I would like to see how you build that in PB3 - Erasmus-bridge in Rotterdam in The Netherlands. Cable stayed bridge with an interesting pylon shape, where the pylon looks a person pulling on a rope. Could you make it work with working bascule? Bonus: a modern Belgian bridge engineer I'm a big fan of: Ney & Partners. Especially "De Lichtlijn" bridge looks like a big elastic bridge that follows the tensions... To hard to make in PB3.

A suggestion for next time: The Hochdonn high bridge in north Germany. It’s a 2,220 meter long, 42 meter high railway bridge above a huge canal

Real BILF for a next episode: Rendsburger Hochbrücke Some background on this lovely BILF. In the beginning of May this year I went on a vacation with a group of friends from my study (Mechanical Engineers mostly). On our journey to the vacation location we visited several awesome spots, one of which was this awesome bridge in Germany. The Rendsburger Hochbrücke was build in 1913, and has a train line running over the top and a 'floating ferry' underneeth. The total lenght of this BILF is 2,486 metres (8,156 ft), and its longest span is 140 metres (460 ft). Also, great video Matt! (and editors ;) ) Looking forward to the next one!

Loving this series! Made me look into bridges I didn't know much about. I challenge you (though it might not be possible) to recreate the Mystic River Bascule Bridge! Also the East Haddam Swing Bridge is incredible!

Matt you need to try the Mackinac Bridge from Michigan. It connects the lower peninsula to the upper peninsula and is one of the longest suspension bridges in the world. And it has a nice under-truss. Everyone loves an under-truss.

The term for the hanging shape the main cables on a suspension bridge (or any other sort of cable or chain too) make is catenary. I think Poly Bridge is giving you something like parabolas, which can be close, but they are definitely quite different.

The Eads Bridge is a BILF! The Eads Bridge, is considered a masterpiece of engineering and a true American icon. Completed in 1874 at a cost of almost $10 million (a significant sum at the time), it was the first bridge to span the Mississippi River and the first to employ steel as its primary material. Designed by the renowned civil engineer James Buchanan Eads, the bridge is a stunning example of 19th century engineering. It spans 6,442 feet across the Mississippi River.

Portland, Oregon has some really nice bridges I'd like to see you try building. Including the St Johns Bridge which is a suspension bridge that was the highest bridge in North America when built (which they built because it was cheaper than a drawbridge-a very Poly Bridge motivation), the Steel Bridge (which has two independent vertical lift decks, and is named that because at the time most bridges were built out of cast iron) and the Fremont Bridge (a tied-arch bridge, which is a type you've never talked about on this channel as far as I remember).

I loved the GREAT belt bridge from Denmark. And your pronunciation was decent. Fun fact: the bridge has one of the highest arches for any suspension bridge because it's considered an international strait and needs to allow really tall ships and oil rigs to be sailed through.

Portugal mentioned!!! Thanks for all the content and fun you've given us!

I have two suggestions from North Wales; Seeing the Menai suspension bridge (built 1819-1826) would be amazing. It was designed by Thomas Telford and was the world’s first major suspension bridge and the longest of its time. Either that or the Conwy suspension bridge, also by Telford, built at the same time (1822-1826).This one was one of the first road suspension bridges in the world. (Conwy’s bridge also fits the in game span limit)

Bridge of Lions, St. Augustine, FL, USA. It's a fairly old bridge (kinda... they recently were forced to rebuild it due to deterioration due to age, but they stayed true to the original in a restoration effort). It's not super fancy, but it does have a drawbridge, which i thought would be fun. St. Augustine is the oldest city in the USA, at 457 years old, though the bridge of lions isn't quite as old as the city, it's still 96 years old. The bridge gets its name from 2 marble lions on one side of the bridge and 2 granite lions on the other side.

Four bridges in Japan that I crossed/visited in 2021: The Akashi-Kaikyo Bridge--明石海峡大橋 The Great Seto Bridge--瀬戸大橋 The Oonaruto Bridge--大鳴門橋 Kurushima-Kaikyou Bridge (technically three bridges linked together)--来島海峡三橋 Every one of them is several kilometers in length, so probably a stretch for this game.

The wobbling of the Green Belt Bridge made me want to see the Tacoma Narrows Bridge

If you want to do another cantilever bridge, the Royal Alexandra Interprovincial Bridge here in Ottawa/Gatineau always spooked me as a kid whenever I went on trips to Québec since the lane into Québec just, like, isn’t paved?? And would vibrate the shit outta the car?? Just imagine being like, 7, on your way to have a blast out-of-province and suddenly there’s a THUMP then VVVVVVVVVVRRR as you’re crossing a bridge. Wild. Edit: Alternatively, apparently the Québec Bridge is the longest cantilever bridge in the world atm, so there’s a probably better recommendation.

The Kaiser-Wilhelm-Bridge in Wilhelmshaven, Germany is pretty nice You should have a look on it opening up. Both halfs of the bridge swivel on their tower foundation. I know, the opening isn't possible in polybridge, but i think it's worth a look outside of videos.

A very iconic bridge I quite like is the Tacoma Narrows Bridge. You could even pass off any breaks as just being consistent with the real bridge XD

Hey RCE, I really loved to see a portuguese bridge in one of your videos. And I am even happier than it happened to be the Luis I brigde wich is one of the best looking and engineered in Portugal, designed by Gustave Eiffel the creator of the Eiffel Tower in Paris.

As a Portuguese, I'm immensely happy for the 1st bridge!! It looks very similar! And a very good detail by adding the little accent over the "i" in Luís!

Storebæltsbroen consists of four different parts. Store: wich meand big (there is also a lille(small)bæltsbroen. Bælt: I Think its just the name of the water it cross. Bro: Wich means bridge. En: It is just something we put on the back of our words if we talk about something specific, like when you say “the”.

"Heróis do Mar", as my portuguese people would say. Brilliant video by the way. Keep the great job and feel free to decrease the lack of engineers in Portugal😂

In Rio de Janeiro, Brazil we have the Rio-Niteroi Bridge, it's huge, it does a big turn and, in a part, it goes up and down so that large ships can go underneath.

This is my favorite series Matt does. Real bridges are so cool.

How about the *Charles Bridge* in Prague, Czechia. It’s a medieval arch bridge built in 1402, and it still works perfectly fine to this day, surviving multiple disastrous floods. Loving these videos RCE!

The Macanac Bridge in Northern Michigan would be fun to watch! It's a 5-mile bridge connecting the upper and lower peninsula and is the border between lake Michigan and Huron.

Do the original Tacoma Narrows Bridge, also known as Galloping Gertie. It collapsed pretty quickly so it couldn’t be that hard. Plus you could fix it

The Viaduc de Millau in France is an exceptionnal bridge, has lenght of 2.4 km and his high is 340 meters. That will be interesting to do it in Poly Bridge !

i havent been up to date with many poly bridge 3 videos, but i caught this one and it was a treat to see you have some many tools in the new title to be able to complete these recreations!

I'd love to see you recreate one of Pittsburgh's bridges. We have a bunch to choose front, but my favorite is the Smithfield Street Bridge with its helix design.

Would be amazing to see you try to build the Slauerhoffbrug in The Netherlands! Would definetely be the weirdest bridge you've ever recreated.

Tsing Ma Bridge is a bridge in Hong Kong. It is the world's 16th-longest span suspension bridge, and was the second longest at time of completion.[3] The bridge was named after the two islands it connects, namely Tsing Yi and Ma Wan. It has two decks and carries both road and rail traffic, which also makes it the largest suspension bridge of this type. The bridge has a main span of 1,377 metres (4,518 ft) and a height of 206 metres (676 ft). The span is the longest of all bridges in the world carrying rail traffic.

Here are 2 bridges from Melbourne, Australia I would like to add - Bolte Bridge - A bridge easily visible from Docklands and Marvel Stadium. - West Gate Bridge - The bridge that goes across the docks of Melbourne and Yarra River and is right outside Southbank and the Melbourne CBD.

Not sure if it's in the wheel already, but I'd love to see the Mackinac Bridge in Michigan, USA. Super cool bridge and sounds like it would be fun to build here.

i saw the fourth rail bridge on christmas day in scotland when i was on my dad's ship (RFA Fort Victoria) truly a sight to behold, i also went under it in a car and stood next to it, also saw a train going over it, such an amazing bridge. edit: this was in 2022

As soon as you put in those first four foundations I knew it would be The Forth Rail. Iconic bridge.

You should definitely try to build the pont de Québec (Quebec bridge). Its history is pretty interesting (it failed twice during construction). Its also the longest cantilever bridge in the world.

Would love to see a side by side of the real bridge and yours when you finish building them, with you pointing out differences etc. As a dane it was nice to see Storebæltsbroen! Fun fact: it was promised that once the bridge had accumulated an income equal to the budget to build it (about 2.5 billion pounds) it would become free to drive on! About 5 billion pounds in income later, we’re still waiting on that promise :,(

You should do the Puente de Triana (the official name is Puente de Isabel II) in Sevilla, Spain. It's not as impressive as the ones shown here because of their size, but it has a lot of history behind it and is the most iconic bridge of my city.

"Sorry kids!" shouted the engineer gleefully, as he watched a bus filled with kids plummet into the water. In a bit of horrendous news today, the Stolbourgshipbreeanburren experienced a catastrophic collapse on its first day of operation. The engineer who designed the bridge was invited to watch as a schoolbus filled with children made the maiden trip accross the bridge. Calamity struck as soon as the bus reached the first part of the birdge that was suspended via cables. Onlookers could only watch in horror as the sound of cables snapping rang through the air. The road gave way soon after and the bus could not be stopped in time. Many reported the engineer shouting "sorry kids!" as the bus sank to its watery grave. Others reported seeing the bridge sway and oscillate ominously the day before the bridge was to be opened. When asked for a response, the engineer started blaming architects and insisted that the failure was due to the fact people were unwilling to make use of what he called "the strongest shape". As of yet, it is unknown to which shape in particular he was referring.

I vote for the Bolte Bridge in Melbourne. Basically a bilf with architect's 'support' pillars which aren't connected to anything. "The bridge features two 140 metre high silver (grey concrete) towers, situated on either side of the roadway at the midpoint of the bridge's span. These two towers are an aesthetic addition by the architects, and are not joined to the main body of the bridge."

Drawbridge over Regalica in Poland The only construction of this type in Europe using a mechanical system - it using weight to stand ( like strongest shape!! )

You should try the Lions Gate Bridge from Vancouver Canada, the terrain on either end is different so it may look kinda cool compared to some of the more symmetrical ones

Btw natural curve for tension bridges is called a parabola and it’s basically a part of a circle, it also never changes through different gravity, fastest way for a static object to get to point A to lower point B, it is the strongest curve for tension and arch bridges. It’s so strong as all the force on the bridge is evenly distributed and I think in this game the starting curve is a parabola.

Regarding the Big Belt Bridge and big ol' boats passing beneath it, it wasn't too long ago that a Finnish made cruise ship, "Allure of the Seas", sailed under it, but, it was so big that they had to engineer the smokestacks so they could retract while going under it.

You should do the Mackinac Bridge that connects Michigan's upper and lower peninsula. It's a little over 8km long and is the longest suspension bridge between anchorages in the western hemisphere!

Would love to see the Samuel Beckett Bridge in Dublin, Ireland built in Polybridge. It is not very long with a span of 123 metres (so you don’t need to scale it) and its shape is very interesting that looks like the instrument harp

As a dane... the GREAT belt bridge is indeed impressive. And when its 2 in the morning, it also works fabulous as a drag strip

The Duluth Aerial Lift Bridge. It's a lift bridge in Duluth Minnesota at the entrance to the Duluth Port. Super cool bridge built right before ww2 and its on the National Registry of Historic Places. It takes about a minuet to lift it all the way up (135ft). The bridge has a horn on it because there is a customary horn-sequence it has with all ships and a special sequence for the SS Arthur M. Anderson because she was the last ship to see the Edmund Fitzgerald on the night she sank.

It would be cool to see you build a lift bridge, some suggestions would be the aerial lift bridge in Duluth or the portage canal lift bridge in houghton/hancock

You should do the Mackinac Bridge which connects lower Michigan to upper Michigan

Your channel is my first ever contact with engineering in any form and It's been a while since a new topic got me so interested in it.

What about building the world's longest single-span bridge (229 meters) dedicated exclusively to carrying pedestrians and cyclists? Its an arch bridge called the "Three Countries Bridge" (France, Germany, Switzerland) that crosses the Rhine. What about adding a tram bridge to the wheel? It's called the Beatus-Rhenanus bridge and (I'm not sure how to describe it) it's a 290 meters double bow-string double arch tram-pedestrians-cyclists bridge that crosses the Rhine between Strasbourg and Kehl. PS: Can't wait for the Millau Viaduct!

Bridge is love bridge is life.

i would love to see you trying to make the longest bridge possible

Port Mann bridge, Lion’s gate bridge, Second Narrow’s bridge and Pattelo bridge (not sure if spelled correctly for that one) are all very neat bridges in Vancouver

i’m 14 and i want to be a civil engineer when i grow up and your the reason for that i’ve been watching your videos for a good 3 years now and thank you.

First

Actually, your Danish was quite a lot better than your English translation of Storebæltsbroen - great build btw, I recognised it right away. You'd translate it to Great Belt Bridge and not Green Belt Bridge :D Funny story about that bridge. It opened in 1999 (before that there was a ferry). My x-husband is also an engineer and we crossed the newly built Great Belt Bridge going on our honeymoon. And he wanted so badly to really look at the bridge and study it carefully for his first crossing of it so I agreed to drive over it for the very first drive. Turns out there was an issue with the payment station at the end of the bridge and we ended up being in a queue all the way on the suspension bridge - driving no more than 20 km/h at any point - so he definitely got to see all the details of the bridge... in slow motion :D Did you know that there's a whole extra section of the bridge called the West Bridge. The one you built is called the East Bridge - and in between the two parts they anchor to an island called Sprogø. The West Bridge is a box-girder bridge that is both for cars and trains. And for the suspension part the trains go down into a tunnel while the cars cross the suspension bridge :)

6:10 I have a painting of this bridge in my living room with the city of Porto (where it is located) behind it :)

Nipigon river bridge in Canada. It's a simple cable stayed bridge but it's got a cool history. When the second bridge section was under construction the roadway lifted on the open side and shut down the bridge for almost 2 weeks. Basically cutting Canada in half and halting all vehicle traffic as no other roadways cross the river.

i like Wadebrkdge's Challenge Bridge, also called Anneka's Bridge, an asymmetrical cable-stayed bridge built in 4 days on Challenge Anneka. it looks weird.

7:36 : Matt: "Unlimited height foundations modifier? That won't help at ALL!"

You know it’s a good day when you get home from work & you see you got a new RCE Poly Bridge video. Suggestion: the Bay Bridge in queen annes county Maryland. Though it does have a curve in it so not sure how that would work lol

The Rio-Niterói Bridge is almost 13 kilometers long and has a central span of 300 meters. The work took just over six years and was delivered in 1974. At the time of opening, it was the second largest in the world. Currently, it remains the largest in concrete in the Southern Hemisphere and the eleventh largest in the world. The bridge has the longest straight span in the world.

Two suggestions for Dutch bridges. 1: The "Python bridge" in Amsterdam (a real RealCivilEngineer type of bridge.. trusses galore 2: the Slauerhoff bridge in Eindhoven... one of the weirdest bridges you ever seen... will need hydraulics though

Hi Matt, amazing video as always, keep up the great work! you should attempt to build the world's largest tensegrity structure, the Kurilpa bridge located in south-east Brisbane, it's a marvellous bridge and I have even had the pleasure to walk across it and admire its beauty in person. I promise you it's not a work of architecture and is in fact a huge feat of engineering!

Add the Verrazzano Bridge to the wheel. I find it very appealing and it is a bridge that I often cross. It is a suspension bridge connecting Brooklyn to Staten Island in New York with two layers of road.

An awesome Bridge for you to check out is the Fort Madison Bridge. It’s a swing bridge with cars on top and trains below. The bridge swings out of the way to allow river traffic through. Obviously the swing function would not be able to be portrayed in poly bridge. I just think it’s a really neat bridge. We used to go watch the trains and the tug boats pushing barges. Was always satisfying watching the bridge swing.

the Arthur Ravenel bridge in Charleston SC, when it was built it was the largest cable stayed bridge in the western hemisphere (it's currently 3rd). Altough the older Grace Memorial bridge would be more interesting in polybridge, as it was a cantilever truss and the diamonds of the Ravenel can't be done ingame.

my great grandfather worked on the Tobin Bridge in Boston. we even have his daily journal with weather and costs of the construction in it. he never actually had a degree but he had a photographic memory and a sharp mind according to my mother.

Please do the Tsing Ma Bridge in Hong Kong at 1377m(4518ft), making it the world's longest combined railway/car suspension bridge and it connects Lantau Island and Hong Kong Island which serves as a connection between the main parts of Hong Kong to the Airport offshore on a man-made island. This is also the longest bridge fully in Hong Kong and also getting lots of love from locals including me, this bridge has been part of my childhood when we were going out of Hong Kong for a vacation and crossing this bridge and looking and it's high suspension pillars and grand cables connecting made me shiver out of excitment, so I beg you to do it just for experiencing it one time.

It's a much smaller bridge, but I love the Dafne Schippersbrug in Utrecht, the Netherlands. Named after an Olympic runner, this bridge is for pedestrians, joggers and bicycles only! It is asymmetric suspension bridge that ends at slightly different heights, with the eastern side leaning on the top of a school!

the skyway in ontario canada. it's a gargantuan cablestay(?) and truss bridge that goes over the point where two of the great lakes meet. I haven't been there in a few years, so it's a bit of a fuzzy memory, but it's awesome to drive over.

Another Scottish railway bridge that you could build is the Tay Bridge. The original collapsed with a train on it during high winds in 1879. The replacement uses upper and lower trusses in the middle and its a real long boi, so it might be a fun build.

When I saw the Forth Bridge, I at first thought it would be the Québec-Bridge, which became infamous for collapsing twice while being under construction, and I thought you wanted to show us what was done wrongly and how it should have been done to avoid the collapses.

The Danyang-Kunshan Grand Bridge is a 164.8km (102.4 mi) long. Now obviously the bridge itself isn't super fancy beyond it's length but that is where the challenge lies! Make a bridge in Poly Bridge 3 where the car drives across a bridge the full scale 164.8km! If u want an even greater challenge have the car drive only 164.8km so it can't be infinitely looping. This is the challenge I pose!... Unless ur just an architect.

If you want to know the first bridge is Luis I Bridge, the second is Fourth Bridge, the third is Green Belt Bridge. Hope this helps!

Don't worry that Storebæltsbroen swayed a bit, it actually does that in real life. It's not that bad tho. Also, I have sailed under it, I have never felt so small in my life, I knew it was huge, but that change my perspective on everything.

“and i would bridge 500 miles(meters) and i would bridge 500 more just to be the man who wasnt an architect” would be a great bridge song

this is my favorite kind of content you put out, I love it so much

If you're up for a challenge translating a weird bridge into game format... The Kurilpa bridge in brisbane (or as we call it the daddy longlegs bridge) is the world's largest hybrid tensegrity bridge. a huge portion of its strength comes from the tension of steel cables pulling against each other, actually a little bit like the cable muscles you put together here.

Would be brilliant to see any of the bridges along the river Tyne especially the swing bridge or the millennium bridge, not sure if they're physically possible but if they are it would be great to see.

The architecture of the Göltzsch Viaduct ("Göltzschtalbrücke") in Greiz, Germany would be pretty cool to see in this game!

Nicely done! I'd like to see you give the Eshima Ohashi a go (the Japanese bridge that looks super-steep from certain photos/videos online)...1.7 km length, 6.1% grade on one side, 5.1% on the other...but I feel the asymmetry shouldn't be a challenge.

You should move next to the Forth train Bridge, it's a BILF paradise, there are three massive impressive bridges right next to each other like a beautiful family. Posted from the Forth train Bridge goodness!

Hi! There is a bridge in my town it`s name is 'Kryukiv Bridge'. In most part it is as simple as possible, just a bunch of trusses, but there is a part in the middle which raises straight up as ships come under. Also its a double deck bridge. Cars a going on top and trains on the lower deck

U should build the Anzac bridge in Sydney. It needs more love bc it gets out shadowed by the harbour bridge

Check out the John T Alsop Jr bridge in jacksonville fl. Its not real big, but its one of my favorites because of the views you can have of it, and the lights at night

Would love to see the Second Narrows Bridge from Vancouver!
