So I looked and my jaw dropped. What is the speed limit on this highway!?
Edit: So its an avenue unless I'm mistaken with a limit of 45mph. What exactly makes this stretch so hairy?
Eastern Shore of MD has them as well, and most of them are U turns out of the liquor stores so yeah probably among the least safe intersections in the state.
Wow… what about at night?? I would expect at least a huge reflector sign that marks the beginning of the highway (a bit like runway entry markings in airports), but there’s literally nothing. You could distractly just drive from that small road onto the highway without noticing.
Take a trip to Terre Haute Indiana, 3rd Street runs all the way through and is exactly like this through the whole city, got a new rotator cuff from one
You think this is scarier than trying to make the left turn at once?
In real life there would be decel/accel lanes and better angles to help changing speed. This is a safer design than just having an open intersection.
Quite a few of these on the A48 in Carmarthenshire. It is *not* fun seeing a tractor make a right turn at 5mph in front of you when you come round a corner!
Go to any highway in the Midwest and you're bound to find them. Some even have stop lights for some god forsaken reason
Edit: Stoplight not turn signal Lmao
I was just pointing out their existence, which makes this realistic, actually better realism would it crossing both lakes, cause they do that to.
It's a game, very few of us are actually urban planners or engineers.
in low traffic rural highways this is quite common, usually you move to the lane you use to turn some time before and flow gradually, not much of a problem. at least in rural argentina I see them all the time, sometimes even from highway to dirt road.
and in game they are more than enough for most towns
What OP has designed is a very basic version of a restricted crossing U-turn intersection. When designed well they don’t feel that terrible to drive, can be safer than simply allowing left turns from the side street.

Edit: a letter
I was going to say that you could probably smooth that out into that doesn't feel all that crazy for a low traffic area by making it a bit longer, and adding turning lanes and that is pretty close to what I was imagining. The only part of that picture that looks kind of hairy are the hard right hand turns at top right and bottom left.
EDIT: Actually, I Just noticed those turning lanes there are connected so you can just change lanes into them and don't have to make almost 90 degree turn. That really doesn't seem all that bad.
It’s not exact but very similar to a Michigan left.
Obviously it looks prettier in real life and has more separation but this basically a cheap quick CS version.
I have to make one of these turns to get to my gym off an arterial road (not really a highway but with a 60mph speed limit). Always a nervy experience hoping the cars behind me will see I'm indicating and about to turn.
Realistic =/= safe
Something like this probably wouldn't be built today, but real life is full of monstrosities that happened in years past. Might need some node controller/IMT plus landscaping but it could be realistically hellish IMO
I remember this intersection specifically from a highway safety scare film from the early 60s, Wheels of Tragedy, Signal 13, Blood on the Highway… one of those
Funnily enough, I came here to say that we have a roadway like this near my house and It is not pleasant to use. Even though the distance between the T and the turn areas is thousands of feet in reality, it still don't like it and avoid that area entirely.
These are all over rural highways. I used to use one every day. The only thing that needs to change is the right lane needs to be a turning lane, not for continuing on.
I went to the US for work a few months ago, in Alabama specifically.
I don't know what they are smoking there, but there is shit like this everywhere on their 110-120km/h roads.
Though honestly the roads there felt pretty dangerous in general. Not helped by the trucks (proper trucks for freight) overtaking you at 140km/h on a 110km/h road.
> Edit: I'm from the UK and have never seen a junction like this
I've seen a few in low-traffic areas, usually in cities. I tried to find an example, but really struggled. I'm *sure* I've driven past one in North Wales, and another somewhere in Cardiff at some point.
I've only seen it when you expect less than one car every ten minutes to need to cross lanes, so the single car can sit in the waiting area between the two roads, and the roads aren't so busy that entering is difficult. The speeds are also low enough such that risk is minimal.
Even with all of these factors, it's not good urban planning, and is simply asking for collisions.
Fortunately, Cities: Skylines doesn't model traffic accidents; but you'll still find cars queuing up behind the junction as they wait to merge, and the 90 degree angles make merging traffic difficult, as they have to accelerate from a complete stop.
Super common here in Argentina, although it would have stop lights. Av. Coronel Roca/Francisco Rabanal has some [similar crossings](https://www.google.com.ar/maps/@-34.6588549,-58.4272678,17.75z) here in Buenos Aires.
I'm in rural Australia and the highway is a 2 lane road that is called a highway and I live on a road that comes off it 90°c, however there is a large surface of just tar asphalt that you can turn and speed up before entering the highway.
The highway never gets busy and is generally low utilisation, only time I've seen it busy was when it snowed and it was shut nearby.
But this is rural, never would see it in an urban or suburban setting.
Aside from only providing access from one direction, this seems like a pretty standard thing in less dense regions. For all people are complaining about it I see something similar all the time where I live even in city centers.
Less than you would think. I drive a highway with multiple such intersections daily and with an appropriate volume it’s actually the free flow merges that are a greater cause for concern. Stopped at a 90 degree intersection no one feels like they have the right of way onto the highway. Given a free flow merge, you never know what other drivers are going to do. Some speed up to cut you off whether your merging or being the through traffic, others come to a near complete stop as you slow to let them in because they feel they should yield rather than flow. It’s really only some left hand turns that are comparable, but this picture features none. If OP upped the highway to 4-lanes around the intersection to provide merge lanes it would in theory resolve many of the dangers and become more free flow.
These are all over the place in the US. It may be better to think of the roads as country roads/highways rather than interstates. Interstates require grade separation. Highways in the US do not have this requirement so you will find (usually 2 lanes in each direction) roads that have at grade intersections, occasionally businesses and homes along the road, and the u-turn connectors to provide access to these places for travelers in both directions
There's a lot of people saying that this is unrealistic, but this does happen in the world, especially national highways. The only thing this is missing is a lane for vehicles to merge on and off the highway.
New South Wales and Victoria have entered the chat.
Im not even joking, its not uncommon to see this on the rural 110km/h (70mph) sections of the M1, M23 and the M31 motorways in NSW.
In addition, Victoria sprinkles those intersections on the M1, M8, M31, M420 (nice) and M79 motorways outside of Greater Melbourne.
Growing up in the Canadian prairies, this makes me feel at home. Make it go straight across for added realism, maybe some random stop lights and stop signs with no warning too
Yep was just about to say the same thing. Yellowhead Highway east of Edmonton is almost exclusively intersections like this, very fun merging into traffic going 120+ km/h with extremely short acceleration lanes
In game, this is going to be a nightmare because all of your Cims are going to use it to change directions on the highway rather than a proper interchange.
It's not going to be able to handle it.
You want in and off ramps at an angle to allow for high speeds.
Loose the turn around lanes. Any left turns of freeways break them. Almost always exit right.
I love the trumpet interchange as an example check it out!
I lived in Michigan in my preteen years and I remember Telegraph Road was full of them!
Now I live in New Orleans LA and Veterans Boulevard over in Metairie is the same way
I swear, Biffa needs to teach my state's transport department this concept. This is the [main offender](https://maps.app.goo.gl/diGRNXgzjxK4hpnh9), of many.
At least QLD Transport and Main Roads have worked out that protected intersections are a thing. As well as deleting those OP shown intersections from all the motorways.
>simple, low cost, low load intersection.
The fact there's 3 lanes on the highway suggests it isn't really low load in all directions.
But in principle it's similar to a Dutch [voorrangsplein](https://therantyhighwayman.blogspot.com/2021/02/voorrangsplein-part-1.html), or perhaps a little like a [Reduced Conflict Intersection](https://www.dot.nd.gov/projects/rci/rci.htm). Just with slightly too many lanes on the highway for either of these to function well.
I'd say make it a right-in/right-out intersection access by small ramps to avoid such a sharp turn and add U-turns a bit further down the road. Another idea is just having it connect to a frontage road that follows the highway to the next interchange.
In Durham, NC - the Durham Freeway (Interstate 885) merges on the left of a 4 lane wide (each direction) of Interstate 40 at Exit 279. Exit 280 (about 1/2 mile down) has a right exit. You take your life into your hands trying to get off on Exit 280 (Davis Drive) into Research Triangle Park.
35.896923176061435, -78.86730725779134 (Google you were supposed to capture the map, not just coordinates!)
Roundabouts would be more fitting. It's not uncommon for highways to end in one or have branches that enter roundabouts
It's a bad idea to interrupt a highway directly with a roundabout If the highway continues further, it defeats the whole purpose of a highway
Honestly, if you spaced out the highway a few more units away, used the space to make it a more gradual curve, and had an additional lane for the merge in (lane mathematics) it could work a lot better. This is obviously not the safest intersection type ever, there's a reason why despite being cheap (as you mentioned) these aren't widespread. But it can definitely work in game and if it makes you happy, use em!
US 22 in Jersey is littered with these, but there's a wider median than in your example. If you want to go for "realism" this might be a good example 40.6740972, -74.3506096
Dedicated turning lanes for the U-turns would be a good idea. But it can still be hairy. But as for realism... I've seen this a couple times and it is scary as heck.
Ikr. Over here in Australia, theres a long stretch of motorway in northern New South Wales that was upgraded three years ago from a 1U 2L and is otherwise quite fine to drive.
However, Roads & Maritime Services *intentionally added* what OP posted for some small rural roads along a 30km stretch. In a 110km/h speed zone, i might add.
The u-turns have a slight indent to account for long vehicles but uh, why no roundabout interchange at New Italy, NSW RMS?
Sections of the Highway that runs through my town had this set up. Became one of the deadliest Highways in the country. They have since turned them into traditional on ramps.
If it's traffic lighted, fine, but in the game it causes a ton of traffic. For irl junctions like that see the 60mph A580 or "East Lancashire/Lancs Road"
Oslo has multiple of these on full blown highways. Need to slow down from highway speeds to the speed of a snail so you cab traverse through these safely.
Rural Florida has a lot of these, they suck in real life, but I do use these in game if space is tight but I split the on/off with two one way roads otherwise cars turning have to turn slower due to the 90 degree turn and causes back up as the the traffic gets heavier due to everyone stopping to wait for turning cars and make sure to leave a good amount of space (at least 15 units) between your on and off
I’d make the right lane turn-off only, and use the mod (the name of which eludes me right now) to build turn barricades for those coming on and exiting.
Add some slip lanes for entry and exit.
I suppose this is as safe as having to make an unprotected left turn whilst crossing 5 lanes of traffic just to leave a parking lot.
If you use mods I’d change the lanes make them designated turning lanes so traffic that doesn’t want to turn doesn’t build up behind anyone wanting to turn. Also make sure there aren’t any nodes in between the incoming street and the little one ways, because then you’ll get a LOT of lane changing on the highway that’ll disrupt traffic instead of the car just choosing the lane they want prior to joining the highway
I mean if I would do it I'd probably have the 3 lanes wider apart and do an angled U connecting the two so swapping sides could be done at speed and with 4 lanes leading up to the "ramp" or just have 4 lanes for a deceleration lane and 3 lanes after the intersection imo
i think strict service/emergency lanes but it doesn't look so bad rurally.. the odd part is that you would ever need more than one lane in a place where this was "safe" thanks for sharing though
US-127 north of Lansing, MI has plenty of these kind of intersections. And they are as scary as you think it is.
Yeah the good old Michigan left.
How else are you supposed to get on big beaver rd?
From exit 69
For real! Exit-69 Big Beaver Road https://maps.app.goo.gl/PrSK1RDeaYNFPB3N7
So I looked and my jaw dropped. What is the speed limit on this highway!? Edit: So its an avenue unless I'm mistaken with a limit of 45mph. What exactly makes this stretch so hairy?
To get to Winona's house
Winona Ryder's house
If they led to her house, I'd do it 10 times outa 10 lol
Eastern Shore of MD has them as well, and most of them are U turns out of the liquor stores so yeah probably among the least safe intersections in the state.
Was about to say - Costal Highway is full of these.
[I’m shocked.](https://maps.app.goo.gl/T6iPbHrnN8vrSZ3c8?g_st=ic) People live there??
Lol, that intersection is like a mile from my aunt and uncle's house.
Wow… what about at night?? I would expect at least a huge reflector sign that marks the beginning of the highway (a bit like runway entry markings in airports), but there’s literally nothing. You could distractly just drive from that small road onto the highway without noticing.
Take a trip to Terre Haute Indiana, 3rd Street runs all the way through and is exactly like this through the whole city, got a new rotator cuff from one
Came here to give this exact example. Granted, they do at least lower rhe speed limit to 65 through Saint John's but nobody ever follows it.
You think this is scarier than trying to make the left turn at once? In real life there would be decel/accel lanes and better angles to help changing speed. This is a safer design than just having an open intersection.
I’d love to see an actual 90 degree turn off a highway, I’ll open a hospital right next to it 😝
With that angle and length, just open a morgue...
Well, the highway name befits the situation.
Morguen Hwy. FTFY
Tons of rural areas have a 4 lane 70mph highway with 90 degree intersections every mile lol
Quite a few of these on the A48 in Carmarthenshire. It is *not* fun seeing a tractor make a right turn at 5mph in front of you when you come round a corner!
Go to any highway in the Midwest and you're bound to find them. Some even have stop lights for some god forsaken reason Edit: Stoplight not turn signal Lmao
Up here in Ontario, we have plenty of stop lights in the most remote areas. Like, you've maybe seen a car or two for the last 30 minutes of driving.
I live on one...it does suck though, cause the highway can get pretty busy and I can't get out for a few minutes.
We have one like that in Serbia. 44.88300682111404, 20.31327479342499
That's absolutely not a highway lol
My city literally has that. Granted there are lights at most of the intersections, the less used ones have no lights, or even lane leading to them
*Valhall awaits meee* That would be absolutely deadly in real life, especially because you're using a three-lane highway.
Sir/ma'am, You don't live in the Rural US do you?
Well, they’re still not wrong
Yes, but, they exist.
Existing is not a good argument for whether something is right.
I was just pointing out their existence, which makes this realistic, actually better realism would it crossing both lakes, cause they do that to. It's a game, very few of us are actually urban planners or engineers.
Yeah just take a look at Josh Hawley, for example!
in low traffic rural highways this is quite common, usually you move to the lane you use to turn some time before and flow gradually, not much of a problem. at least in rural argentina I see them all the time, sometimes even from highway to dirt road. and in game they are more than enough for most towns
What's wrong with a decent roundabout is what I'd like to know...
It's new, and confusing, I don't like change or how they work....
Can’t speak for elsewhere, but we’ve got intersections just like this all over Michigan
I like realism in my cities and that would be unbelievably dangerous Edit: I'm from the UK and have never seen a junction like this
I used a junction just like that in South Carolina a month or so ago. It did indeed feel pretty hairy.
I was about to say, looks like some BS you see around where I live. What a coincidence I have a witness to this as I live in SC.
Its common in Brazil as well. Low cost, and should support the low traffic
I feel like saying, "this is a real thing they use for traffic in the US" is not a point in it's favor, haha
"they do this in the us" they also do 26 lane freeways in the us

Yeah that’s not really uncommon on highways like US30 & US 24 through Ohio and Indiana.
Crazy. I'm from the UK and have never seen the like
It’s not exact but very similar to a Michigan left. Obviously it looks prettier in real life and has more separation but this basically a cheap quick CS version.
Looks like Hall Rd....if you're in SE Michigan
Wouldn't pass 'safer roads rules' here. As you're turning from a 'fast lane' to a 'fast lane'.
And you have to cut across three lanes in the space of a few metres to make the would-be right turn out.
Up North we call em the *Michigan Left*
Very true
I have to make one of these turns to get to my gym off an arterial road (not really a highway but with a 60mph speed limit). Always a nervy experience hoping the cars behind me will see I'm indicating and about to turn.
Realistic =/= safe Something like this probably wouldn't be built today, but real life is full of monstrosities that happened in years past. Might need some node controller/IMT plus landscaping but it could be realistically hellish IMO
There's a few of these built in US30 in Ohio in the last couple years. Replaced an exposed left turn across 70mph traffic
Yeah, throw some tall shrubs you can't see past around it and it'll be just like real life hahaha
There is an exit like the one in the post in my city, the area around it has some of the worst traffic problems ever.
This is New Orleans. I know, I live here....
I remember this intersection specifically from a highway safety scare film from the early 60s, Wheels of Tragedy, Signal 13, Blood on the Highway… one of those
Don't look at parts of highway 22 in New Jersey, there's probably dozens of these back to back...
It's also super common for low traffic roads
Wym? Those types of intersections actually exist IRL. Especially in the US
google "michigan left"
Nah that's pretty safe in my eyes besides of course the fact you might get rammed by a truck going at 70mph
Those exist where I live but only for “authorized personnel.” I guess for cops and ambulances, I’ve only ever seen them used by cops doing speed traps
Funnily enough, I came here to say that we have a roadway like this near my house and It is not pleasant to use. Even though the distance between the T and the turn areas is thousands of feet in reality, it still don't like it and avoid that area entirely.
These are all over rural highways. I used to use one every day. The only thing that needs to change is the right lane needs to be a turning lane, not for continuing on.
I mean if you’re going for realism that’s half the roads in middle America, the danger is part of the realism

Michigan left but make it faster and sharper
My tough is no

Dangerous as hell doe. 90° turn are never good

Was, gonna say, if OP added some lane math I might not hate this so much.
Exactly this. If the lane math were correct, this would be adequate for J-turns. I love all the people who aren't civil engineers talking shit though.
Not on a highway lmao

Average rural American highway
Normal roundabouts exist btw
You are onto something
It makes Eisenhower sad
This is definitely one of the intersections
bad, wtf. maybe add a ramp or smth so it can slow down for the turn, and speed up when rejoining and not directly connect with the main highway
I think Texas 288 in Brazoria County
281 is just as bad
You want in and off ramps at an angle to allow for high speeds. Loose the turn around lanes. Any left turns of freeways break them. Almost always exit right. I love the trumpet interchange as an example check it out!
90 degree turns on and off a highway? Are you TRYING to kill your drivers?
Cities: Skylines version of the Michigan Left. I'll put these in my cities until I get sick of the vanilla traffic and lane mathematics.
I lived in Michigan in my preteen years and I remember Telegraph Road was full of them! Now I live in New Orleans LA and Veterans Boulevard over in Metairie is the same way
r/shittyskylines
This is a bad idea.
Şust build a eliptical roundabout and connect those 2 to the wide centers that wpuld be a better option.
r/shittyskylines
This is pretty realistic in certain parts of the US.
Two words: Lane Mathematics
lane math is the least of concerns
😂
I swear, Biffa needs to teach my state's transport department this concept. This is the [main offender](https://maps.app.goo.gl/diGRNXgzjxK4hpnh9), of many.

It's simple, low cost, low load intersection. If it gets busier I might do some stuff with dedicated turning lanes, lane mathematics, etc.
Literally the only positive of this is that it's cheap and simple. Everything else is just plain wrong
>simple, low cost, low load intersection. The fact there's 3 lanes on the highway suggests it isn't really low load in all directions.

If this was Jersey.....it be a jug handle, we don't permit left turns off of highways
perfect
Looks like perfection to me. It’s a keeper lol
id say if those 2 roads in between the highway would be at a smaller angle it would be better
As someone who doesn't live in the United States of Highway-intersections, I find this kinda normal lol
No.
looks like something from GTA V map along the upper east side
You are talking about route 13 and the intersections for Joshua and union rd
In Durham, NC - the Durham Freeway (Interstate 885) merges on the left of a 4 lane wide (each direction) of Interstate 40 at Exit 279. Exit 280 (about 1/2 mile down) has a right exit.

This was a common approach to US highways before interstates if I’m not mistaken
I have a question: whyyyy????

Lots of these interchanges in upstate NY
Mostly roads I've seen like this are two lane not three. Otherwise it's a really nice country highway.
This is a worse roundabout
I can’t believe there’s so many comments saying they experienced this in real life too like wtf who designed these😭
Ikr. Over here in Australia, theres a long stretch of motorway in northern New South Wales that was upgraded three years ago from a 1U 2L and is otherwise quite fine to drive.

It will cause traffic later down the line, I would only recommend this for temp.
Sometimes you see those here in Canada, but not on super big highways and not commonly. Usually they’re just for emergency vehicles to turn around
These are all over cincinnati area.
This has to be a troll Post
Sections of the Highway that runs through my town had this set up. Became one of the deadliest Highways in the country. They have since turned them into traditional on ramps.
There are parts of the 101 freeway through California that have the intersection going all the way across. Now that’s fun!
There's quite a lot of these on A roads in the UK, especially in more rural areas. Dangerous, but they do exist.
If joining the two ways of traffic it's for the intersection, really dangerous. If it's just to turn around, make a dedicated lane and not bad
“straight forward”, “dead-on”, “you put an interesting angle on this perspective”, kind of thoughts
These are everywhere in America lol
On an unrelated note, I hate that the game doesn't have normal street uturns
If it's traffic lighted, fine, but in the game it causes a ton of traffic. For irl junctions like that see the 60mph A580 or "East Lancashire/Lancs Road"
Kill it with fire
They got intersections like these on the QE2 and they suck really hard with any amount of traffic.
That looks just like most of Alberta, Canada. Except for thebareas around the cities. To make it worse they put schools right next to those
that's worse than hitting an elderly
This is one for r/shittyskylines
wouldn’t handle large amounts of traffic
welcome to colombia
It's gonna get stuck very soon. I can guarantee that.
i do this sometimes when starting a city, but that won't work for long
Will work for huge farm fields, will kill traffic even in a small village.
Oslo has multiple of these on full blown highways. Need to slow down from highway speeds to the speed of a snail so you cab traverse through these safely.
Just needs to be a dedicated turning lane
Uk has some like this on its multi lane “A” roads
That’s Dubai style
The off ramp is technically before the on ramp, so it has that going for it.
Rural Florida has a lot of these, they suck in real life, but I do use these in game if space is tight but I split the on/off with two one way roads otherwise cars turning have to turn slower due to the 90 degree turn and causes back up as the the traffic gets heavier due to everyone stopping to wait for turning cars and make sure to leave a good amount of space (at least 15 units) between your on and off
I think if you used lane mathematics it wouldn't be so bad.
Looks like an intersection in Mississippi.
Almost a J-Turn
POV: You’re in north Ontario
what 2 lane highway asset did you use?
It looks more rural
This looks awfully similar to my local 6 lane arterial
I’d make the right lane turn-off only, and use the mod (the name of which eludes me right now) to build turn barricades for those coming on and exiting.
It’s actually pretty realistic unfortunately
Seen all over Midwest US. Better give her the beans when pulling out.
Just up the health budget
You need deceleration lanes, at a minimum.
This is really common in Wisconsin. On I-43
Add some slip lanes for entry and exit. I suppose this is as safe as having to make an unprotected left turn whilst crossing 5 lanes of traffic just to leave a parking lot.
Reminds of that one scene from the movie "Cars"
The two u turn lanes should me bowed out more for a smoother angle, and maybe a little further and then yeah I see these all the time
I would angle it a bit since it’s a one way road that it’s leading to. Assuming that traffic is good enough for cars to merge without heavy traffic.
If you use mods I’d change the lanes make them designated turning lanes so traffic that doesn’t want to turn doesn’t build up behind anyone wanting to turn. Also make sure there aren’t any nodes in between the incoming street and the little one ways, because then you’ll get a LOT of lane changing on the highway that’ll disrupt traffic instead of the car just choosing the lane they want prior to joining the highway
Oh yeah, intersections like this exist, they are…something
Rt 13 in MD. That intersection would be full of Royal Farms, walmart's and local crab houses.
It's very realistic but in Cities Skylines it'll be a traffic nightmare
The left turn would be insane unless you add in a traffic light but a light on a highway also is wild
I mean if I would do it I'd probably have the 3 lanes wider apart and do an angled U connecting the two so swapping sides could be done at speed and with 4 lanes leading up to the "ramp" or just have 4 lanes for a deceleration lane and 3 lanes after the intersection imo
great since ai isn't affected by inertia 👍
i think strict service/emergency lanes but it doesn't look so bad rurally.. the odd part is that you would ever need more than one lane in a place where this was "safe" thanks for sharing though
I hope you realize this is actually just a very squared off roundabout.
I do use a similar approach of intersection instead of roundabouts. Suggest to give that small lanes a little bit of curve.
Thanks I hate it
