Diverging Diamond Interchange Tutorial (DDI) - Cities Skylines

i did it as an underpass on a few maps

I usually use a height-separation of 12 for crossings. This is more than you need for normal roads but clears the electrical pylons on railways and trams (and probably trolley busses). If an intersection is entirely ground-level or raised I will usually provide underpasses for pedestrians, otherwise elevated walkways. One 'feature' I think is nice for larger intersections is also providing a cable-car crossing.

Yumble, I need to know how to make the perfect hydro power dam. I'm an XBOX player, so it's probably a little different on game consoles, but still. The road stuff has been hella useful.

Check out the I-70 and US-50 interchange on the west side of Grand Junction Colorado. It's a diverging diamond that goes under.

I got a suggestion. Try 15 units.

I got a good way. Think of a diamond.

Hii how come the texture of your grass and 'hillside' look different from mine in Vanilla... is this a different texture mod or something? Thank you~! nice guide i will try this one also

Have you tried doing junctions on a bend?

Why the roads on your videos so dark it looks cool is that a mod?

YUMBL, I'm curious if the DDI can be done with 3 nodes, using expanded nodes with node controller kinda like your recent SPUI. You'd have to use a reversed-direction road asset for the middle segment, but I think it could be a much tighter design?

Make sure to include a power backup generator, since this "design" without powered lights is quite dangerous... Second, if you make the overpass bridges two lanes wide, you don't have the merge issue. They did this design near my home (in hurricane zone) without a generator. They put lights at the ends of the offramps as well. The idiots that designed ours planted palm trees that blocked the view of the red lights in the middle of the interchange. It also really confuses foot traffic crossing the bridges, since they cross to the center and then back out to the side of the road for the sidewalks. They also marked the traffic lanes at the outside of the curves, not the inside. So, anyone who is going too fast in the marked lanes will hit the curb or wall! I always drive the inside of the curves, despite the markings. I would have preferred the DDI with two tunnels and zero lights. None of the locals likes this intersection, so it was put here against our objections.

I want a stack.

I'm not a fan of the diverging diamond interchange, but I am a HUGE fan of your work! Your more recent works are even more polished and professional.

what mod are you using to show the unit distance for the roads?

Hey can you do a pinavia?

A pin agua interchange

How do you manage pedestrians around interchanges?
Me: I don't ¯\_(ツ)_/¯ simple

underpass where i am - I-75 and University Parkway have a DDI built as an underpass. I’d assume it’s much cheaper

It's not really so much better than normal for a game, but in real lif it's supposed to lower accident risk. Personally I think this ain't anything a roundabout couldn't fix.


What you can do in cities skylines is remove the cross altogether and make it a twist over/under pass rather than an interchange.

I used to live near Dorset Rd and Interstate 270 in St. Louis, which is a DDI that runs through an underpass. I have heard it's the first DDI west of the Mississippi too! Thanks for the welcome tutorial!

did you ever end up doing a traffic light tutorial for this interchange specifically? wouldnt you want the crossing light and the other crossing light green at specific times so traffic doesnt stop on the overpass?

i miss the ddi in my hometown so bad 💔 i live in henderson nv now and its cloverleafs and diamonds as far as the eye can see

I built a diverging diamond interchange in the Asset Builder using vanilla highways and no mods. I had to make the arterial an over- and underpass on to the highway for it to work. Otherwise, that junction where the vehicles have to crossover will never work.

when i first made it in Cities skylines i didn't mind realism that much so i went for a small ugly bridge/tunnel to replace the intersections so there wouln't be cars crossing eachother at all.

Morgantown wv plans to convert 3 of 5 interchanges (exit 152, 153, 154 on i79) to diverging diamond

I built it, but you have to post a tutorial on how to set up timed traffic lights. Please!

No traffic lights, yields

I put pedestrian paths along, over, or under service interchanges

Those triple trees on islands look a little bit strange since they are blocking view. Except that - awesome!

The pillar is dangerous though. Imagine flying at 100km/h / 60mph, loosing control for whatever reason and crashing into that wall.

i use h:9 as a minimum for my bridges.

can you tell me what road are you using and how do you get two lane ighway

Beautiful.

This is very common in the Netherlands (slightly differently configured with more straight roads and T-junctions). However in the Netherlands it is preferred to have overpass elevated due to the high ground water levels. So I think it is important for realism to avoid building underpasses when constructing near the seashore.

It's just a diamond interchange, it's not diverging.

Is it possible to replicate in full vanilla game?

I have a feeling that making them function is the easy part for you, and most of your time is spent making them look so incredible

Yooou knob.😂I said it to the car that did the weird thing at the time when you started to do traffic manager

you can also do sloping with network multitool

I put this into asset manager and it barley fit but now I can use my own

Drainage.
You made a pond.
Does it even rain in CS?

Z fighting, not zee fighting.

I tend to divert peds by building a paralel collector to my arterial interchange. also try building ped overpasses, i treat them the same as my roads with grading and landscaping

How do you get the right lane to be a continuous right turn? TMPE won't give me a seperate light to keep it green

How come these tutorials feature roads in the middle of nowhere, and they are never a part of a bustling city?
