Elevate Your Downtown Intersections with "Vanilla Overpass Project" 

I love the look of that, nice! :-)

nice. i've always wanted this in my high-density cities. this was sorely missing from the gameplay.

You're a lifesaver! I didn't know about the need to brace the nodes to avoid those B sections from messing everything up. Always wanted to try an overpass from one direction and a tunnel from the other, with dedicated right lanes on the ground level so the only intersection would be the left turning ones, as well as incorporate some kind of overpass in a continuous flow intersection. Got me pumped up to get back into the game

Wow! Placed this in one troublesome intersection in my city, and now everything just FLOWS! Thank you so much.

absolutely brilliant. Having this issue right now in my city with arterials backing up, and no room to build a large interchange. The lack of room stems from smaller land area between rivers.

They have a lot of intersections like this in Bangkok. What's interesting is they usually disallow right turns (they drive on the left so that's the wider turn) altogether in situations like this and then provide a U-turn slip lane, so to make a right turn you do a left turn and then a U-turn. It's kinda weird but it works. From what I've heard they don't have eminent domain so the government has to come up with really crazy solutions to traffic sometimes.

I tried these roads and got them to work but they are such a hassle. While your method of starting from the middle is an improvement it still ignores the fact you are using them in a confined space. Try using bracing roads when you are upgrading a busy junction surrounded by existing buildings. Another issue is the blue mantle shows through unless the roads are perfectly aligned and that’s harder if the roads are not perfectly straight and at 90 degrees. When they work they are beautiful but it’s a laborious task. However, another great video and very informative. I love the way you explore advanced topics in a clear and precise way.

Been sitting on this for months and finally had a use case for it in my city and it cleared the traffic completely. thanks for the tutorial. I did have some issues getting parts A and B to connect properly and had to re-build that step a couple times but i got there in the end.

You could make right turns free-flowing by giving them a dedicated lane. One lane each way for straight ahead should be fine.

If you do a single lane crossed bridge like this, and another that's tunneled, you could have, say, North-South traffic making left turns on the bridge and East-West traffic turning left in the tunnels and have all continuous left turns.

literally the best RU-vidr for the game no joke! love these videos makes it so easy to build and learn

It's a cool system, some cities have this, and you can indeed change it depending on where most traffic wants to go. You can simply have about twice as much traffic going at the same time, ish.

This guy's intersections ideas are just so creative space saving and interesting both in functionality and look

Good stuff! Gives you that Northern Virginia feel: lots of money for roads but no eminent domain.

This is amazingly confuse. Thanks for share the bypass roundabout!

I'm glad you clarified at the beginning, because I only clicked on this because it said Vanilla

I love this. There's something with a similar vibe in my city and it's quite practical. Thanks for another awesome recommendation.

That is so cool, I have tried making things like that just using anarchy and move it and just get a mess. Definitely going in my mod collection.

I've just started watching your videos. and I cant get enough... Congratulations on being the reason I fall back in love with Cities Skylines!

I love your intersection and interchange so COOL!😊

This could be a good way to set up a small footprint junction between two motorways, since the biggest problem with vanilla + node controller roads is that to have your slip roads that change elevation, they can't be too close. Using the Opposite - the outer lanes rising/lowering with the centre lanes at level, you can have a stacked junction in a smaller footprint. Lets take an example: A North/South highway A East/West highway. The N/W is on elevated ground already and the E/W highway was cut into the ground to create grade seperation. Instead of adding in the slip roads far back to provide sufficient time to weave over/under, or even over and OVEROVER (over the highway that's already higher than the other)... A small roundabout is constructed at halfway height between where the two motorways pass each other. for the N/S, making it is the same as the initial part, except that you slope the grounded road between the two grade heights. The E/W likewise, slopes the grounded road between the two grades but the centre lanes road is made as an at-grade ground to tunnel, OR, the centre is grounded and the outer is 'Elevated'. (would that even work?)

ooooo, thanks for the upgrade (turn off collision) tip!!! I was wondering how to get pillars to work! Great Video as usual!

Oh man! I think I saw one of these when my wife and I took our trip to Dublin on the cab ride to our hotel! I'll have to give building one of those a try.

thx for the tutorial! i downloaded these a week ago and it's been sitting in my assets unused ever since

Sounds like I'm going to love this. Doing the same with node controller, move it, and fine road anarchy is a pain.

Very cool. Once again saved to my CS playlist

This video has changed my life!!!!

This is what I have been looking for!

WOW! That looks AMAZING!

Love your assets in the workshop I always get them 😂😂

Thank you for the great tutorial! WIth the video coming with Vanilla Overpass I coulnd't get it working. Your way is working much more consistent. Beside that I really like how you work out all the details in all of your videos.

Elegant and compact! Looks good!

ah, the braces. one of Yumbl's tips I should always remember.. previously took me so many redo's/undo's to finish just one overpass.. 😅

Cool will check it out thanks for the video :)

This intersection is common in Jeddah, Saudi Arabia with over and underpass. And the ground level intersection is for turning left and right.

Thanks, very interesting, Happy New Year, cheers. :)

awesome mod highlight! thanks! like that you showed your road lines too! enjoy your format!

Ingenious use of a very handy mod. Thanks!

"See? I do things" :)) priceless. subscribed

Thanks for making that so simple and work so well

I'm so glad I joined your discord. I am watching this 5 mins after it was uploaded

Another great video but where is new market? It's been months!!! Happy new year!

This is so cool thanks for showing it.. i downloaded it right away :)

Ahhh awesome! I'd tried this mod awhile back but couldn't figure it out from the description on Steam. Feel like the assets are named in reverse haha. Definitely gonna have to give this one another try :)

and another great idea to implement thanks!

Cool asset, nice detailing

This is a quite interesting idea to grade separate a 4-phase intersection into two 2-phase ones. I guess we don't need to sync the top intersection with the bottom one at 11:43 so they can have more flexibility :-)

I like your first idea better, the one where straight-on traffic goes to the overpass. If one road goes to an overpass, and the other goes into a tunnel, I think it would work.

Yes! I have never seen anyone make a center turn overpass in city skylines before.

I did this on the highway test map but with straight though traffic. And then made a roundabout underneath. With some clever TMPE lane connectors you can make sure the roundabout doesn't offer a straight through route.

Love it. 👍👍

huh, this looks very similar to the middle-interchanges on the 290 near chicago. harlem ave exit is the one i'm thinking of. it's a system interchange rather than just an intersection. would love to see your take on how that interchange works and what you think of it, especially since it forces the CTA metro track to move to the side of the highway instead of in the middle like the rest of the blue line on that branch. actually any interesting interchanges that exist in real life would be neat to see you dissect and "fix"

Nice space saver.

This mod is great, and has saved me so many times. The only bad thing is that it doesn't have a trees variant, or bus or bike lanes, or any of the other variants of a vanilla six-lane road. And for a final bit of nitpicking, I also wish there was a variant with unidirectional underpasses with the underpass not being centered with the rest of the road, just so I could recreate a very specific intersection in my hometown.

Love these videos

the tutorial i needed

there was this game called "Intersection Controller" that has the second configuration from this video and called it "Center Turn Overpass", its pre-built into the game

i would love to see this but with trams, trains, and US style roads. i would use that a lot if that were the case

This is the most realistic intersection other than a simple traffic light for me...

I have gotta mess with this once I get a day off.

Very good explanation

Always great.

I feel like you could use reversed roads for the overpass in the overpass left turn configuration, and create a variation on the counterflow intersection.

No lane connectors, no round abouts... MY kind of gameplay! And to think i discovered you because of the king of Roundabouts :P

If you make east west go straight through on an upper level, and north south go straight through in a tunnel, you can make both left and dedicated right turns in the middle.

It looks like you've re-invented the "Center Turn Overpass" -- or at least that's what VDOT's site calls it. Definitely a fun way to split the traffic to two two-phase lights!

Oh. I actually got roads with the labels A, B, C on them (it’s a tram road). I didn’t realize this is how you use those kinds of roads and I have been using them recklessly in my builds and i did not understand why they keep clipping (yeah yeah, I should have read the description 💀). Anyways, this is really cool. Thanks!

Seeing that junction during the intro before the change makes me want to cry. 😭 Also, as much as I like the look of this, I don't like the idea of awkwardly fudging things to make them work. But I hope the devs take notice of stuff like this and make the game legitimately support that kind of functionality.

Hi, Nice work as always I have done something similar with no mod, used plan roads( single and dual lane highway ), North -south uses overpass to continue 180 degrees straight ahead, and east west use a underpass to do 180 degrees straight ahead

I hope they allow us console players the option for this sort of stuff in Cities Skylines 2 🙏🏼. This looks so amazing 👏

This would be way cooler if you could add basically two ranps side by side at different heights, allowing for a stacked intersection. So say the west to north is set at 12 high same as East to South. South to west and north to east are at 24 high. No lights, no congestion. Can't see this working unless they mod it to offset the ramp all the way left or right instead of center. Or a mod that allows you to convert lanes into a raised ramp.

I have (effectively) the same mods as you and this still looks like absolute magic!

You make it look SOOOOO easy and SOOO Nice... I tried for over an hour and could never get it to work. I build the 2 lane road over then the C and B sections want to lift the ground and build up at the same lever as the over pass. I tried building the C/B parts first and then the over pass, and got funny glitching at the end points with with look like DEEEP holes. No matter what setting I put it on, Normal, Build Bridge, or any combo, could not get it to work... It all stars on flat ground too. Only thing that was different was they were not 6 lane roads but not even close to getting them hooked up. So have to try again another day.

Finally some attention on this mod!

I like to see you do it with a 8 lane avenue and a 2/2+2/2 overpass (north to south) and a 2/2+2/2 tunnel east to west ;)

There's one interchange that I think you would love. It was designed a while back by a streamer by the name of freelancer Alaska. It was quite a bit ago now and I'm not sure if any recorded footage of it exists anymore but I know he posted the sketch designs on his Twitter. I'll see if I can get his permission to share the picture with you on yours or in your discord. But it was an interchange that was almost entirely at grade level but still didn't have any crossing traffic. It was very large but very visually appealing and very efficient

In downtown areas it would be great if this way of separating left turns are under instead of over the intersection

It would be interesting to see variants on this idea. Like if the left turns were a roundabout above the intersection, or if there was a way to make this a triple-stack (maybe one curve is overground while the other is under). Either way, this is a fun idea and is a nice way to keep traffic to a minimum.

A traffic circle killer. Nice! I wonder if this will play nicely with Roads United.

Those overpass left turns are a brillant idea for using the vanilla overpass :O

neat! i've seen similar, but, the overpass is not over, and it's under (but not underground). still, kick ass setup.

Reminds me of Florida, seems really complicated though.

You should write a book about designing overpasses and interchanges. I'd just call it, "The Art of Turning Left."

To fix the first round about traffic .. change the speed of the over and under to faster so it becomes priority. I think I saw a few going straight.

Damn this is pretty

This is great! Thanks YUMBL. You mentioned about the ability to do a tunnel version. Do you have one or plan to do one? Would be great to see

I think it is more beneficial to traffic to have one left turn using overpass and the other using underpass :)

Would you consider doing an in depth look at the Building Theme Manager? I get asked about it all the time in the FB group and there are plenty of players who get stuck. Common issues are the difference between styles and themes, not realising you need to download all the assets, that you need all types of buildings (RICO) in your themes if you want to assign it to the whole city, that you need all the levels of buildings and that a 1x2 can only upgrade to another 1x2, etc.

I know I'm a few weeks late, but none the less; I like to use these in 2 ways: high flow 4 way intersections I'll do an overpass in one direction, and a tunnel in the other. At grade is for left and right only, with right turns being conflict free. Allows a 2 phase light to handle everything (larger node so left turns at the same time.) Secondly, and similarly, I'll use it to create a semi high flow service interchange where space is premium. The highway gets it's overpass, the side to side gets a tunnel. I'll bring the highway ramps to a single point interchange at grade, and a 2 phase light handles all the interchange traffic quickly. These 2 methods allow me to upgrade low density areas to high without reworking my road network.

I tried to build an overpass like you did. I gave up and used move it on your asset and moved the elevated parts where I needed them.

Could this be used to make a compact 4 level stack for 100% free flow? Hmm, to the drawing board!

thanks for your vid ive created a city full of overpass😂

Straight through in one direction on overpass, other direction through tunnels. This essentially allows straight and right to never stop and you only have to control left. Maybe?

2:20 If you make the ramp a bit longer (9u, not 8u) you probably won't have to create a brace between C and B roads like at 3:45, as the game is unable to unify the two segments, as the sum of the lengths of the segments is greater than 12u. 5:37 If I'm not mistaken, the overpass ramp road is already acting as a brace.

Everything is great in these videos that help our cities funktion in the right way but wenn is newmarket returning? Love the hustel !

This seems like it would also be useful for tram road intersections, so the trams don't interfere with traffic flow.

Can you do an underground pass and an elevated pass on the same road? I was thinking keep the left turns + traffic lights + pedestrian crossings at ground level, elevate one direction straight-trough and right-turns and sink the straight-through and right-turns on the other direction. That way we get no crossing traffic on the straight-throughs and right-turns at all, only on the left turns, which is why I rather have them on the same level as the pedestrian crossings, which get in the way... if at all possibe?

Very clean 👌🏽

Now this is more efficient. I actually designed a proposal to a city of a similar design. Where cars would go underground to take turns without waiting at a light. This allowing two sides to be green 50% more of the time. Tripling or quadrupling efficiency. The town had an odd intersection where only one side could be green at once. With a flow rate of 90 cars a minute. And 7 cars through per green. It was awful.

Waiting for a no overlap intersection, basically just have left turns on opposing sides go underground and the other 2 stay above ground so they don’t overlap and then there’s no stopping
