Why doesn't this layout exist in real life? Cities Skylines 2!

We're checking out Cities Skylines 2 (City Skyline 2) today, and this time I get sent an interesting looking intersection layout that I recreate in Cities Skylines 2 to see why they don't exist in real life!

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 🤣

That's not a cloverleaf, mate, it's a uterus. You've birthed quite possibly the world's first uterinterchange.

[acockroft]

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.

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.

[TimmyTonk]

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

[Mike__B]

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.

[andybrinegar]

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

[TheEpicDragonCat]

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.

Shouldn’t this be called the UNLUCKY clover leaf? Since 4 leaf clovers are the lucky ones? Architect move rce, architect move

[bergar]

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.

[jAujAl]

Can we take a moment to appreciate the transition at 1:56? It was actually really smooth.

[Poptartsicles]

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.

[blackoak]

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

[cdwarrior]

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.

[stolenromeo]

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.

[tigrecito]

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...

[johnm]

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

[spell_me_right]

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😂

[gwalla]

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.

[proletariennenaturiste]

19:17, those would be the most dangerous crosswalks. Cars would roll back onto you, semis would roll forward onto you.
