Recreating the WORLD'S WORST JUNCTION in Cities Skylines 2!

My logic here is that they could not by all the land necessary to build a proper intersection, hence the field in the middle of it, so they had to do with little space

My guess for why they didn't go with a cloverleaf is that since the surrounding area is full of farmland they either couldn't or really didn't want to take up any more space than absolutely necessary

99% of "why" questions in germany's road engineering are answered by "because the farmer doesn't sell"

If you're going to be doing cursed interchanges you need to do the entire point area in Pittsburgh where multiple highways meet up and split apart. There's a two lane tunnel in both directions and TWO double deck bridges that are four lanes each way. It's always carnage. Even the inbound traffic on 376 coming down the hill to the tunnel entrance is carnage. Beautiful view exiting the tunnel but the whole thing is crazy.

My guess is they couldn't get the land from farmers to do a true Clover leaf so this is what they were left with.

This interchange looks a lot like a trumpet interchange. My guess is it was originally designed to be a trumpet interchange, and those crossover roads just allow the fourth direction, probably very rarely traveled, to merge into the highway

The reason why this was done the way it was done is quite simple: It's not a Autobahn Kreuz. it's just a two a roads intersection - and unless it's clogged all the time it very well serves it purpose for the amount of traffic there already is. There's really no reason to make driving a care more attractive if your bottleneck is one town over.

You could probably ask City Planner Plays - he had a whole episode of his CS2 series talking about eminent domain for putting interchanges in farmland. In my city we do have some roads with 55 to 60 MPH speed limits with honest-to-god stoplights on them. It's always seemed bonkers to me, but they've been there for years so I guess it must not have killed too many people

Check the bigger picture: yes, the junction is awefull. But there should be little traffic to handle. The road is the state road B3, intersecting the intercityroad L3129. You only use the B3 when you live in one of the nearby villages or the city of Butzbach. If you drive the highway, avoiding the B3 and using the highway A5 into A45 is 3 minutes faster, while 3km longer.

I think there is not much traffic coming from the town (east) onto the north-south road. Most people probably take there the exits further north or south to get from the town onto the north-south road. So the main traffic in this interchange would be cars going north-south or east-west (staying on the main roads) or going from the west on the north-south road. And those connections are far better then the ones from the north-south road to the town in the east.

10:04 You forgot, In Germany most cars are NOT right-hand drive. So it is a bit tricky to look that direction from right window.

It looks like there's an abandoned rail line to the east. Maybe that also limited the amount of space available, particularly if it was active when built?

Say hi to Paddy for me!

My guess is the farmers didn't sell

Can you answer some questions? 01. WITHOUT MODS, can pedestrians actually walk on Alleys and on Gravel Roads? Didn't have time to observe. Under what circumstance do they walk on Highways? 02. What are the criteria that enables a non-service or non-delivery car to drive on a Pedestrian Street? And does the relative close proximity of a cop car have an effect on this? 03. Is there a direct connection to the number and types of out-of-city connections with the number of people potentially moving in and visiting my city? 04. Is there some added technical first responder difficulty layer if an accident is in a tunnel? 05. Does Noise and Air Pollution only bother Residential or does it also have an effect on Commercial and Office? 06. Is there like a general engineering rule or advice about how many 2-way highways are too many to avoid making your intersection a sort of (possibly "turbo") roundabout? How much is too much not to use a roundabout? 07. Do all taxi stops get supplied with taxis from all the taxi depots on the map? And do they get some sort of smart distribution between the stations from all depots? 08. Can you supply me with some semi-large chart of tested numbers about which ?x? sized Residentials, or Commercial, or Office, or Industrial fit under what type of bridges (road,train,subway,...) of what elevation height (or how much relative height difference)? 09. Do you know all the zoning sizes for Waterfront Housing? 10. If when starting a new map it doesn't have snow but is indicated the lowest temperature can be below zero can snow occur? And where? On high mountains only? How do I know it will happen without speeding time through a year?

The Brüttiseller Kreuz near Zürich is probably the most famous roadblock in switzerland. Back when i was still listening radio, it was always in the traffic news and it looks horrable on google maps.

my guess is that you only would take this way if you want to take the scenic road to the village Pohl-Göns (beatiful name btw.). Otherwise you would just take the exit 1.5 km before. Same with the other directions. So I would say this arm are there just because why not. I would asume this intersection was heavily planed on what are arms people would actuale use regulary. That doesn´t mean that they are stupid :). But I am just someone with no backround in civil engineering. what I find quite amusing is the course of the B3, how it is sometimes part of a motorway and then simply continues as the B3

I'm not even an engineer but even i was facepalming as we went through the structure of this junction 😂

There is a rail line in the south-eastern quadrant. But that rail line just dead ends 2km further north. Now, sometimes the railway operator needs those tracks for shunting or parking wagons, in which case they aren't as redundant as they seem. But even with the rail line immovable, it looks like it's still possible to put EITHER a left turn loop (8m elevation increase on 200m ramp, 4% up slope, as at 19:00) or right turn ramp (11m drop on 360m ramp, 3% down slope, as at 17:44) in there. Either one of them would eliminate 2 of the 3 conflicts on the eastern side of the B3. I would personally do the left turn loop. Especially with how that turn is prioritized over the even the straight movement at 16:28. Coming from the south and wanting to go towards the east you can easily use the previous turn off from the B3 onto "Gönser Straße" instead (the right turn at this interchange might even be prohibited to eliminate the last crossing conflict in the east). And finally, building the left turn loop first would allow you to put the right turn ramp in once the railway becomes removable.
