Why do highways have to be one direction roads?

[Ser Cartoon of House Head]

Not sure about other countries but in the UK most motorways are one wide strip of concrete with 3 lanes going each way separated by a metal crash barrier in the middle. A road like that in thei game would be nice as always having to have 2 highways is a pain at time and just looks messy.

Like when you start a new city you have to somehow accomodate 2 one direction roads to merge into something like a 6 lane road but it just never looks right.

Because of ingame limitation. How do you want to connect a ramp to a highway in your case without creating a intersection which would mess up your highway? Furthermore it's just more advantageous to seperate them into one-way roads.

Even at the start of a new city, traffic will need to leave the highway and shoot off in different directions, so connecting a highway directly to a 6 lane 1 way road or any type of single road isn't efficient. A splitting mechanism like a roundabout or a squarabout (diamond interchange included in case someone was about to suggest it) is an ideal way of enabling highway traffic to disperse.
In a new city, I usually use something very simple like this,

That can later be upgraded to a larger version if traffic inreases beyond the capacity for that road.

I was thinking this too, there should be two-way highways in the game the width of the the four lane roads with a crash barrier in the middle isle.

I typically leave a 6 cell space down the middle of my highway to allow for on and off ramping which is crticial in game, otherwise they will be major congestion on the exits and entries, especially if you have an intersection city, I only use roundabouts and the Toggle Traffic Lights mod to help ease the lights used on my roundabouts.

@Bushman82 You get this in the Mod "german roads" ..
4lane- "Autobahn" with 2 lanes in each direction..

You can use the 6 lane two way road, it just permits building on it. So realy you would like that road but with a barrier on it and no building permitted. I guess it would make laying highways easier. I just the two way 6 lane sometimes and don't build on it.

Isnt there a slower speed limit though on a normal 6 lane road?

Yes, of course, because a 2 way 3 lane/1way 6 lane is just a large road and not a motorway.

And usually one lane is always taken up by parked vehicles.... really what it the point in a 6 lane raod when only 4 lanes are actually used?

Anyone else notice also, all the low density houses have driveways but everyone parks on the road? No wonder you get trafic jams all the time day and night.... ok day....

Poiint being they are not really a good alternative to highway for connecting districts.

Boss, you got it wrong. It's 6 + parking.

[Ser Cartoon of House Head]

To be honest I have never looked that closely. Being a neat freak it always bothered my how many cars are cluttering the streets. I wish the game had car parks.

[Stealthy]

Use the roads with trees. No parking allowed along them.

I was not aware of that, thanks :)
