That's not a cloverleaf, mate, it's a uterus. You've birthed quite possibly the world's first uterinterchange.
To my mind, the default interchange he replaced is the uterus-looking one.
Reminds me of the Martians from the 1953 version of "The War of The worlds"
better bulldozer can delete the pillars and then you can double click on any point of a bridge to add a pillar if you like.
What would we do without mods :D
@@Valay0r play a diffrent game
On / Off ramps angle is too severe & abrupt is why
You would think that all the land being used is a waste but here in Arizona the middle "unused" parts of the leaf would be turned into a water retention basins. While the Phoenix Metro (aka "the Valley") is all desert, when monsoon season roles in, any rain that lasts longer than a few minutes will flood the freeways. So, any "unused" land is actually used to shove flood waters into. If it rains enough to flood the basins, then we are in trouble 🤣
This is it, space isn't wasted if you find a use for it!
Hopefully Arizona uses that water for something other than big water features around the expensive homes... right?
In the middle and north of Alberta, they like to put bogs, sloughs, or ponds in there, too. Good ferda berds.
If the roads are elevated or at least separated with a barrier, it would also possible to have a park in the middle.
@@HappyBeezerStudios Let's have a picnic and play some catch this weekend at the fucking highway junction
My inner Biffa was screaming "LANE MATHEMATICS!!!!" I would have not increased to 4 lanes to make up for it, I'd cut it down to 1 lane for all those off shoots.
You underestimate the amount of traffic that will be visiting Engineeringdon! One lane is not enough!
@@RealCivilEngineerGaming one more lane will fix it!

Shouldn’t this be called the UNLUCKY clover leaf? Since 4 leaf clovers are the lucky ones? Architect move rce, architect move
Yeah I wouldn't call it a Clover Leaf at all it really doesn't look like one I would instead call it either a Trefoil or a Celtic Knot
Lungleaf.
YHeah, but could you imagine how jinxed it would be to call a potential design "Unlucky"?
@@TheGreatDrake Celtic knot is a bad ass name for a highway interchange. Love it
Ehh… Triple Clover Interchange
Because it takes up a ton of valuable land and the only addition is the ability to do a "U" turn.
Get rid of the bulbs, slim it down and you have a typical 3 way junction
The tall bridges over the clover exits could connect to the roundabout. As it stands, only one of the three ways can get to the industrial entrance. Technically they could loop around all cloverleafs, but a simple exit before the bridges could make things easier and smoother
Yes, it would need an exit ramp on the bridge and maybe even an entrance ramp if you need to continue into the city and the current ramps are for the third lane...the city out lane would need to circle a big.
This would be a total chaos in the ideal solution that is a mess and works perfectly.
If you have a highway triangle (0,120,240) and the areas in between would require connection to all directions this could be a solution.
But ifa main road is crossing the exit and entrance would be probably at 0 and from that you have access to the other two arms and 0-120 and 240-0 would be connected. If the area between 120-240 would require connection I guess there would only be an exit in the inbound connection and entrance from outbound on int 120 and 240 arm, they would connect the main with that area and the in and out from the 0 arm would be over the main... untill they probably notice the traffic is blocking the main and convert the 120 and 240 to full exit and entrance ramps
Those Clover Leaves are not useless, one extremely useful point of them is to allow Emergency Services to turn around onto the right carriageway for RTC's on motorways and diverting calls etc
Usually in real life there will be gravel emergency-only u-turn points along the highway.
@@Yay295 Exactly, there are far, far cheaper ways of having turnarounds for emergency services than installing enormous, largely unused clover leaves.
Of course they are not useless. You can use them to change highways if you just drive them two times in a row.🤨
I dont understand what the problem is
@@epox_ ...which is literally the exact same as taking the offshoot around the clover leaf
@@epox_ If you want to be as precise as possible, they're not useless - they're wasteful
You should definitely blur out the addresses on those letters. At least the info of the people sending you the mail, if not your own.
I was just about to say the same thing. His address is just a PO BOX thing, so not super important from a privacy issue, but the return addresses definitely are.
nah, i disagree.
As a well trained bar man (an student engineer) who serves a lot of guiness I would like to point out that the 3 leaf clover is not the lucky one and it is in fact the 4 leaf clover. You only draw a 4 leaf clover on a persons first guiness as that is the lucky one every other should just be served with a 3 leaf.
He did say the 4 leaf was the lucky one
4 leaf is pretty standard, 5 leaf and above is 'lucky'.
No logo on the foam
@@pbsixgun6 4 leaf are honestly quite rare, 3 leaf are super common though
@@SebastianD334 percentage wise maybe but if you look in a clover patch for about 5 mins you can find at least a couple

id love to see a historical version of city skylines... my idea is this:
you start maybe in the middle ages and build a small village based on medieval technology... you get maybe a year to try to get your village to be how you want it to be
then at the end of the year, time moves forward say, 50 or 100 years... the ai decides a bunch of events that happened in that time period.. maybe a plague, a fire,
a war, lots of immigration, floods, prosperity, meteor strike, revolution etc etc... when you come back youre in a new age with new technology, new buildings, some of
the original village has changed based on the ai random events.. you then have another year to make changes to your village that is now a town, try to make it prosperous
then another 50-100 years goes by etc etc until you get to the modern era.. therefore you kinda get to design a city in a more realistic way...
anno 1800 have it.
You've just described Civ 6 districts and unit traffic because of single lane roads to each city. OR that's just Anno 1800,
Try Anno 1800?
Transport Fever 2 is gud, but theres no random events. You directly control city growth
Save for major catastrophic events like great fires, natural disasters, wars, etc. I could see the beauty of such a game.
You may end up with a historic district built near a freshwater source, consisting of narrow alley ways, low buildings, and a religious building at the center. Factories will be built down river, on the shoreline, near a train station, or a highway exit. Great fun!
Can we take a moment to appreciate the transition at 1:56? It was actually really smooth.
We absolutely can.
I have never seen more realistic roads
Three things:
1. You don't always need to transition to four lanes before splitting into two two-lane arms. Three is usually sufficient, as the middle lane can become the left lane of one arm and the right lane of the other. Also, someone in the far right lane realising they need to head left only needs to make one lane change. Four lanes can be beneficial when combining two-lane roads, however, as merging introduces risk.
2. Where the leaf connects to the industrial area could have been done with a single two-lane bridge if you used smaller leaves inside the larger leaf.
3. A vehicle heading from the industrial area to the city via this junction will need to travel via all three leaves. It works, but a slip-road might be prudent.
Instead of a high bridge and a low bridge under it, you could make the 2-way loop much closer to the junction and use two straight low bridges to run over the 1-way loop. Less expensive, more compact, and safer due to fewer turns.
How about using a roundabout?
19:17, those would be the most dangerous crosswalks. Cars would roll back onto you, semis would roll forward onto you.
I really loved your transitionts in the beginnging! They where great!😊
Wouldn't putting the roundabout on the leaf after the industrial road passes under the arm be better? No triple stack.
Think he could leave the roundabout where it is and not need the triple stack, there's no need one lane needs to be on a particular side if it's going into a roundabout. Or delete the roundabout and keep the stack.
that‘s what I was thinking too
The roundabout is indeed kind of redundant as it is now.
It could be used to connect the crossing ramps to more than that one distributor road. Or you could skip the triple-stacking; which would save you the expense of one bridge, at the cost of lowering the throughput by forcing traffic to give way to each other when crossing over. Or you could use the roundabout to connect extra ramp connections to the 3rd level of the stack. Or any combination of these.
Or you could eliminate the roundabout. After all, anyone who comes up the distributor road and doesn't actually want to join the highway can use the 3 leaves of the clover interchange to turn around.
Rather than a roundabout *and* a bridge, since that connection to the bulb acts as a service interchange (connecting a surface street to the freeway network), you could just take a cue from the Diverging Diamond and use a traffic light to control the crossover. Game-wise you could get away with just the roundabout but realistically that seems like a recipe for atrocious traffic accidents.
You want a dastardly challenge? Build a city with all of its roads underground! Except the ones that need to directly connect to buildings, but only one road segment per building is allowed above ground! Each building needs its dedicated road leading underground! Use taxis, buses, trams, and perhaps consider subways! Even handle pedestrian traffic underground! Imagine underground roundabouts! Imagine multi-level underground beehive roads inside mountains! Constantly keeping an eye out for underground traffic jams! Perhaps test out a tornado? Underground clovers?
This shall be called: Gopherland? Molenia? Burrowy? The Dig Republic?
And another different challenge: You can only build ANY building under bridges!!
Just regarding the title - because it requires three giant loops so that people can turn around and go back the way that they came. Almost nobody would ever take those sections of road in real life (the 3 oval lobes around the center, I mean).
RCE casually doxing return addresses at the start there
If you make one leaf in the clover leaf extra oblong you've got a really strong shape.
My favorite part of the blueprint is that not only is "coming" spelt incorrectly with 2 m's, but the letter O in "comming" isn't a full circle at the top and kinda looks like a U.
Can't believe how fast that pupper grew into a full size dog
That was so SO lovely! It’s a Celtic Knot! Nice work Alex! (You too RCE).
[and Paddy].
Cheers, Alex! Great blueprint and design!
AND it looks like the cross-section of the strongest shapes main shaft....
Hence the efficiency 👍👍👍
These cloverleaf arms are some sort of a roundabout, which gives you access to every arm of the highway junction, but i have to admit this junction is rather inefficient and complicated to drive.
One small addition:
Add slip lanes from the roundabout to the outer loop to allow left turns both into and out of the industrial area.
At the moment, a left turn would require 3 stages!
sometimes, you need to turn around on the highway using a special intersection, because of construction on another intersection that blocks a road that you would otherwise take
so for americans needing to take a left hand turn, but the left hand turn leaf is obstructed or under construction, you may have to take a right, and then two lefts at the next one (assuming they are the same) which will then take you the same direction you originally wanted, but effectively uses a turnaround
theres also the fact that the highway may be faster than driving in-town, especially to turn around, as some layouts may make it nearly impossible to do so safely, which is why you saw that garbage truck use the leaf to turn around, because it was faster and easier than using the city streets
The tornado highway spiral is cool. Imagine being caught in a tornado on it though, you'd be dead as the entire thing collapsed.
That one garbage truck showing why it's a good idea to have service ramps once in a while. Reminds me of an interchange we have around here. Trumpet shape with service ramps on two ends. The third end service ramp functionality is provided by a "regular" grade separated junction.
Concerning the 6-way functionality: The only case around here where this occured, they simply built 3 cloverleaves.
Staying with this design however, the additional ramps would make much more sense with a bridge into the void left by the indirect ramps and using a trumpet design. You might as well include direct ramps to the outer two-lane ramp at that point as well.
Also coming from that industrial area, using a third lane at the end creates a continuous loop, making it way easier to get in the direction you want without constantly merging. It'd be a weirdly shaped roundabout.
You're definitely an architect at heart.
Wouldn't you save a lot of road and space to put the roundabout directly into the turn around on the cloverleaf? Then you wouldn't need the crossed roads, or the extra junction before the overpass. Plus it being a roundabout has no negatives there, since the turn around gets very little traffic trying to go straight through it.
The only purpose of the leafs seems to be U-turns. All of the other directional choices are possible without them, is much simpler, and absolutely does exist.
1:32 I thought i loved this channel already but to see a fellow drummer brings me pure joy 😂
Actually if you think about it, what this design gives you is the ability to cross over a highway without using overpasses an making turns that will slow traffic. Imagine you're coming down the left hand highway going east (because you're an evil brit driving on the wrong side). But your house is on the right side of the highway. You could either come to a complete stop, turn right and go over to the other side and back. Or in the 3 leaf clover , you take the leaf and never slow down.
Ah, the fabled "SCP logo interchange"
Ah the ol' "cervix layout", a classic
This was really cool to see you take a design and then flesh it out into something more useful and functional.
The trick with the poo container is to put a damn at the outlet to make power from poo.
And the 3 way cloverleaf is probably rare because of it's size. And it requires the three roads to intersect at somewhat symmetrical angles. The T-interchange allows for for a break-off from a straight through road.
Oh, and great that you have Move It there, basically an essential tool for smooth curves. I know dragging roads around isn't realistic, but in reality things would be planed before built, so all that smoothing would be done before a single trench is dug.
It exists already. That's effectively a 3 level stack interchange, but using more Right-of-Way - ie more land purchase.
It would seem the most efficient use of space for the 6-way would be to turn left towards the interior of the u-turn loop, then roundabout and bridge over. Probably not the cheapest, but at least you don't have huge ovals of unused land.
Here at Dragon Transport LLC. We appreciate your support for U-turns. As most people know we always go the extra mile. Usually after missing the last exit.
Now I know why Matt doesn't like night cycles in games. He has a massive window behind his screen. There is no contrast in the world that will make his life easier with that setup.
One of the sacred rules of road building is to minimise traffic disruption during every moment of construction. Minimal disruption is preferred to fastest possible construction times.
I didn't expect to see my monitors on someone video, best monitors in its class
I need you to make a part of your city where it’s like millions of roundabouts to make sure your 100 bri”ish lad
He's done a city like that already
@@TheGreatDrake I know, but I said “a part of your city” not a separate city
I actually think from a real life perspective the turnarounds make sense, as it allows for less bridges to be built along the highway to connect sid roads to both sides of the freeway and it creates a constantly flowing junction, saving money and time.
It’d be more realistic if you didnt soften the landscapes as much, so it looks like real road cut ins. You could add vegetation to mimic humans doing revegetation after earthworks
You know Matt, I've been watching you for well over a year now. You help me fall asleep some nights, you help stop my boredom and you get me through a lot of bad days. Thank you, Matt. you're a real one without even knowing it ♥
basically a t or y interchange that allows u turns. maybe if all of the highways ad buildings on either side? but realistically they’d be accessible by collector streets
im sorry what..........DRUMS! got to see more of the drums!
Did you miss my 1mil special??
@@RealCivilEngineerGaming You're wearing a cap instead of a hard hat on those drums, sir! How could you?!
Good one, Alex. That's as good a design and drawing as any CE has ever done.
The issue of that side thing you added is that you can only get there from one of the 3 main roads.
To get there from the other you need to use up to 3 different clover turnaround parts, that will cause a lot of congestion.
That roundabout could've been used to reduce that triple stack bridge mess down to a regular bridge system to sort the lanes into the right order, that's what roundabouts are for!!
I think the not turning around part might be somewhat of a regional thing. I tend to agree, but I know on some of my trips to Mexico they don't have left hand exits, but they do have exits that basically just go up and over and turn you around. So inside of exiting left off a highway via something like an overpass at each exit, you would drive down the highway a little further and turn around at that overpass, then make a right hand exit. Seems a bit odd at first, but kind of makes sense as well in some ways.
Best setup and dog and drums ever bro nice room cant lie
You dont need the outer loops and the design with them creates more crossing over of multiple lanes at merge points and uses more land which could end up more expensive than the overpasses you saved, if you look at the intersection of the West Gate freeway and Western Ring Road in Melbourne you have a major three way that gets everyone there without loops and with the ability to get in the correct lane a long time prior ALBEIT with more overpasses
2:27 Exactly what an Architect would say.
How does nobody talk about those incredibly smooth transitions
At the end I was shouting at the video. You should use the space inside the clover leafs for the turn offs/ons. Underground turn off that can be both single lanes.
Love the “looks good from my house” moment
better off with a trumpet in this scenario. Allows the through motorway to continue with no disruption and only has two bridges. It also fits quite snug in your location aswell!
I'd like to see a city where your different sections of the city all have one central roundabout that you have to use to get into the different parts of the city/area. So a road system like a kod draws the sun.
I think a lot of road designs Matt doesn't get because he is from the UK where they drive very little compared to the USA, and the land to cover is only about the size of one North Carolina. Where I'm from actually. We would prefer they stop building roads for all the tourists to move in anyways, go around and only come here for relaxation spending their money.
But yea, Matt calls turning around useless all the time. I imagine he simply doesn't see such long stretches of road without exit or petrol as we do with his country being a little short compared to countries like the US or Texas 😅 my local next turn around if I forgot my wallet is about 20 miles (32km) until the next exit.
This is so cool to try out an idea.
You can also connect roundabout of 4th road to the bridge in front of the leaf.
Your intersections make me happy in my special area
21:00 No, you don't need that extra bridge: make the _entrance_ to the clover leaf first, then the exit. Then they are in the correct British order.
1:50 What an absolute legend!
“This interchange doesn’t have that many bridges, so I suppose it’s pretty realistic.”
*Laughs in Texas*
Missed opportunity to make an extremely efficient design in that junction
Man...his fanmail is just overflowing!
I was just wondering if you had uploaded a CS2 video and then the notification came from Heavengineer
You actually do not need those cloverleaves even to add the possibility to tarfic turning back on the highway. Just add lane between both roads before intersection and make 180 turn.
Thumbnail looking like a productive system
almost proper lane mathematics XD like others mentioned 4 is a bit nuts but the middle 1, where you cross the 3 directions you could do with a 3 lane since you have 2 main and 1 incoming from the "clover" that, after crossing the mid-section, goes off the clover again. there you could leave 2 way again. but other than that its neat. also i think the roundabout is kinda pointless, when you already match the laneside. except for, if we are realistic, forcing a slowdown
You should do a video where you engineer a viewers city/fix it - i think that would be a pretty cool video
So, the reason you've never seen a junction like that is because of its space usage _combined_ with the fact that it doesn't really do anything other, more efficient junctions can't. You could just use a 3-way flyover or trumpet instead.
There is two main reason why that type of layout don´t exist.
1: It feed back in the crossing. This create unnecessary traffic. While that is also true for a 4 way cloverleaf. To make a direct access 4 way highway crossing, there need to be 8 bridge interconnect as well as 4 ground level interconnects, on top of the normal crossing. This make it so a 4 way highway crossing with direct access often need to be either really large, or be 4 levels.
2: its really large.
Making a 3 way highway crossing with direct access you only need 2 crossovers and 2 side ramps. And well the main bridge. So making a 3 way direct access highway crossing is actually quite simple not that expensive.
Of cause, making 2 of 3 way highway crossing would be cheaper and easier than making 1 of 4 way crossing. The main drawback of that solution is that it will have a capacity limitation between the two 3 ways hence that solution is typically not used either.
You should visit Texas. All of the highways have service or frontage roads with businesses on them.
It is not uncommon to drive down a highway toward a business, get onto the service road, essentially make a U turn and drive back a mile down the road you were just on to get to a business.
“This is Britain”
3 seconds later:
*Tornado so strong it completely destroys buildings*
If you want to go from the industrial are to the city, you now have to drive 2.5 circles first.
Come onto the highway through a clover leaf, drive the clover leaf towards the solar farms and the drive the clover leaf towards the city...
thanks alex s for the letter. i will download citie skylines and willl try out this intersection myself. Looks realy intersting. I will test this intersection with right side traffic and check pros and cons
The Industrial Road being on that leaf means that if it wants to turn left it has to go through all three leaves
I kept thinking of the Cologne-Heumar Autobahn triangle that is local to me. Not sure, this design might actually be an improvement for that.
the intersection of 416 and 417 in Ottawa Canada was my first though.
I feel like it's rare in real life that a highway ends while intersecting Into another. Also this layout makes it expensive if you ever decide in the future to have the north/South highway continue north.
bud that does against in spartanburg sc heading into nc on the i85 highway.
"It's a work of art." Careful. Almost sounded like an architect there...
I think the better way to go about this would be to make the entire midsection of this crossing, the part that's like a triangle, raised. Then you have the cloverleaf blades coming off of that.
22:20 you did a round about you didn't need to cross the road😮 and at 17:24 you only need 3 lanes instead of 4, just my input! Love your videos keep it up!
You should probably set up some water purification on that human waste mountain thing
At that point of confusimg people just putting a roundabout at the end of that highway lane was peek comedy xD
HWY 401 & HWY 427 in Toronto, Ontario, Canada is basically that but contends with 27
Defo should be called the cucumber junction.
I feel like this should have been a large 4 lane roundabout, where the two lanes that split off are then also added to merge on..
you should look at the highway interchange between south field and I-96 near Detroit Michigan. It has a ton of massive bridges
