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.

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.
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!

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
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
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.
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!
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"?
@@WintersMinion Celtic knot is a bad ass name for a highway interchange. Love it
Ehh… Triple Clover Interchange
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

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.
Actually, the bridge makes the roundabout superfluous.
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.
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.
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.
Yeah, I'm totally into the turning around thing. It's one of the neat bonus features of a round-about - it's a built in U-turn if you just keep going.
@@Lord_zeelI like getting on a roundabout for 450° to make a right 😊
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.
Can we take a moment to appreciate the transition at 1:56? It was actually really smooth.
We absolutely can.
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?
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).
Okay yeah the ovals are stupid, but, unless you’re going right, the loops give you access to both turning around AND the left road way. Unfortunately if you’re planning on going left you’re going to have to take not one, but *two* needlessly long loops buuuuuut it kinda looks like fun to drive on 😅
I think his bio should be "I play every game in every way other than the one it was made to be". I can't even tell you how much you make my blood boil with your goofy actions. But you're also entertaining. Which is why I keep coming back😂
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!
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.
19:17, those would be the most dangerous crosswalks. Cars would roll back onto you, semis would roll forward onto you.
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!!
I think I'd like it more leaving the pedestrian traffic aboveground.
@@Dansiman1 That would make more sense, by my idea is more like a meme.
14:21 - Follow the Arrows. The REAL Reason this doesn't exist IRL is cause the inner loops JUST Turn you around from going one direction to the other on the same road. In all three cases. Cut out the inner loops, and then shrink the interchange lanes back in.
That was so SO lovely! It’s a Celtic Knot! Nice work Alex! (You too RCE).
[and Paddy].
I have never seen more realistic roads
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.
It looks pretty, but there's a better way with fewer bridges and less pavement overall:
1. Put the 2 lane corner sections inside the leaf instead of outside. Less payment, no bridge needed for the leaf feeder.
2. Leaf feeder can enter the roundabout from the right and exit from the left. You'll get traffic crosstalk like you do in a 4 leaf clover, limiting throughput, but if it's not high demand it would be worth the upfront and maintenance savings of not having a bridge.
AND it looks like the cross-section of the strongest shapes main shaft....
Hence the efficiency 👍👍👍

Thanks for teaching me the Nice™ maths. I did not know this, and I do not know if I will ever need this, but thanks.
A T - junction can be made non-conflict with a single bridge. Have the side road cross the main road over the bridge. On the far side, the main road has an off-ramp that turns through 90 degrees onto the bridge. Then the on-ramp turns through 270 degrees onto the main road from the bridge, turning inside the 90 degree off-ramp. On the near side, both on-ramp and off ramps are straight-up 90 degree outside turns from/to the side road. This is the simplest and cheapest way to create a no-conflict T-junction.
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 tornado highway spiral is cool. Imagine being caught in a tornado on it though, you'd be dead as the entire thing collapsed.
Can't believe how fast that pupper grew into a full size dog
21:35 No need for an (expensive, lots of maintenance) bridge to swap the roads over. Two ideas:
a) Have the two "wrong side of the road" lanes, enter the roundabout at 120 degrees apart (as well as the normal road be the third junction of the roundabout.
b) Make the two roads curve (like the shape of a lightblub) and to be the T arms of a T-junction, add a traffic light, to connect to the normal 2 lane road (at the top of the lightbulb shape).
Generally, you don't want to make a U-turn on a highway... unless you're in New Jersey! Highways not only have businesses whose driveways are accessible only from/onto the highways, but also residential streets. So in order to access these places, you must go past them, make a U-turn, and then get back on the highway headed in the opposite direction. It's absolute madness! And if you miss your turn, well then, you've got two more U-turns to get back to where you wanted to go (or slam on the brakes, throw on your hazards in the shoulder, and throw the car into reverse... never my choice, but I've seen it plenty of times).
The cloverleafs would be good for "rest stop" type commercial areas (fast food, gas, vehicle sundries), or even commercial/industrial shipping hubs. Things that you want to have maximum exposure to highway traffic, without necessarily having to dump out into your city proper to get to.
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.
people wanting to use the exit on the leaf would have to go through all three leaves if they come from the left (if the city is at the top as seen at 24:48). you might want to add a few more bypasses from that roundabout.
Ah, the fabled "SCP logo interchange"
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
@@WintersMinion I know, but I said “a part of your city” not a separate city
Cheers, Alex! Great blueprint and design!
The means to double back on oneself can be a god-send when an accident or road works mean the exit at the previous junction is not usable.
I'm also one of the weird ones who when I first saw the road plan of Spahgetti Junction wondered why everyone seemed to find it complicated.
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's fine in a game but to answer the question in the title, one word, money. That's a whole lot of real estate and excessive paving and support costs (signage, structural support, etc) when a well built roundabout or intersection would be 1/10th the cost.
[RealLife] put it as the center of a minor city, normal suburbia outside, except no "convinience" stores. have a convenience sector which is the internals of the clover. this sector is then designed for tourism.
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
Mjah, flyovers are the most expensive and also the best. In The Netherland we have many “clover leaf” crossings and they just congest when it is very busy. Just fly over.
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.
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.
What a cute dog! He should have his own channel. Maybe he could take you on walks, and maybe carry a stick.
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.
Coming from the industrial area via the roundabout, cars can only go “straight”. To go towards the solar farms, they would have to go round two clover leaves, wouldn’t they? So perhaps add another pair of ramps from the roundabout to the bypass that bridges the crossover?
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.
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.
"IT kinda looks like a slice of chili or a slice of cucumber..."
I just see a face screaming into the void of industry.
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 ♥
Would suggest moving the roundabout into the cloverleaf to eliminate the triple stack flyovers. Removes some of the aesthetics, but seems to be a low flow road primarily for heavy goods bypass.
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.
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...
You had a working 3-direction highway interchange and replace it with a far bigger and costlier one to add the option to turn around a tiny bit sooner. "Pointless" does not even begin to describe that. This is a really high-cost active danger to everybody.
you now have a u-turn where there are more lanes merging into each other inhibiting the flowing traffic - and that on the outside of a turn (where you do not want to have any changes in lanes).
For the upgrade to 6-way, I'd have left the outside portion on ground level, and used bridges to convert the feeder lanes to left-side driving. Gonna need bridges anyway, better to make them smaller.
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.
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.
You can force roads you lay to be a bridge part even on the ground (or change them after the fact) then raise or lower them as needed.
Scenario: You have a major population center off to the west and a shopping center at the northwest corner of the interchange. Using u-turn loops for that traffic kinda makes sense.
This is CS2, cars turn around for seemingly no reason all the time. I had to redesign whole junctures just because u-turning cars were blocking traffic.
I was not expecting to see a 3 leaf clover today
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!
Ah the ol' "cervix layout", a classic
In the real world, decreasing radius turns are particularly dangerous for trucks and motorcycles - both of which have a limited amount of traction that can be spent on either turning OR braking. Constant radius turns and loops are safer since they are more predictable for drivers/riders.
As a Lori driver, clover interchanges are the bane of my existence
You could put the roundabouts inside the cloverleafs and have a bridge to the roundabout.
It would solve the wrong side of the road issue and also no need for the other bridge to go over it.
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.
Heads up, you missed some blurring.
The thing you call "the bum thing" looks like spades, then you constructed clubs this time, so now we'll need hearts and diamonds as well to make them complete
You could have slip roads to the centre of the leaves for industrial centres or farms.... That way the produce could be easily and efficiently transported in any direction
Because it does exist, it's just not as bloated and large when its implemented in real world situations.
Versions of this idea literally surround the downtown area of Houston.
“This interchange doesn’t have that many bridges, so I suppose it’s pretty realistic.”
*Laughs in Texas*
You're definitely an architect at heart.
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.
*peers at thumbnail* Adding a place to crash on the highway because you missed your turn isn't the best idea. Forced weaving is just asking for trouble.
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.
20:58 you could a clover hoop instead of a direct connection
Slightly different layout of the on/off ramps but this is exactly what Spaghetti Junction in the UK is (in terms of the highways themselves)
I doubt think you need the 3 bridge set up in the centre of the interchange. 1 normal bridge, 1 ground level and 1 underpass with small bridges crossing. Underpasses are cheaper to build IRL than spans
They have a couple intersections like this in ann arbor, without the unnecessary cloverleaf
Missed opportunity to make an extremely efficient design in that junction
the three curves aren't needed, they only make U-turns considering you can go two directions from each way without the cloverleaf circles.
I mean, it's just a cloverleaf with 3 leaves instead of the typical 4 leaves. Hardly revolutionary, and there are trivially-better ways to connect the ramps.
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?!
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.
The added exit/entry on the clover could skip the crossing bridge if the drive on is before the drive off.
It exist near Palmanova, Italy. It does have the U-turn roads however.
