Highways are expensive to build but they are important for shifting high volumes of traffic. Most of the traffic will be towards the cargo terminus. Once you have rail then that would help transport goods around.

Once you get more industrial areas and they start becoming larger, it is very important to have a road layout that can deal with high volumes of traffic and having dedicated connections for them to the highway network. I've usually built my industry separate from the other city, having access to that roundabout.

How I've started usually is to build a roundabout on your first interchange.

Placing industrial zones next to highways is recommended. You'll need enough products though, so make sure you have a lot of industry. Those disctrict-policies generate a lot of tax-income because commercial buildings start selling more products. If you are having problems with generating enough income it might be nice to look into the city-planning policies Big Business Benifactor and Small Business Enthusiast. These roads look kinda cool but I haven't used them that much yet. The Network Extensions Project recently added some new roads that are intended for neighborhood-traffic (tiny roads). You could see a picture of dirt-roads in a village near my city below: These roads are very cheap but you could get traffic jams if you intent to use it for something else than local traffic. These roads are for local traffic only and don't need to handle that much traffic. I only use them in villages outside of the city where there are no future expansions planned. Thus when starting the first approach might be better. I could upgrade these roads to 6-lane or 8-lane roads if needed and it works better than two one-way roads. In those cases I'm often building two-way roads like you could see below: Especially at junctions you could get into trouble. However, when I'm zoning a new area with as main goal to make it high density from the start this approach might work less good. This solution is quite cheap and is good for further developments in the future. The two one-way roads you can see were upgraded to two 4-lane one-way roads, which makes it a nice boulevard that could handle a lot of traffic. Still I'm using roads with the same width in here. All the buildings are high density and all the green places you can see in the distance are being developed. I'll give you some examples below:Ībove you could see a photo of my city when I just started with it. You could actually really lower costs of roads without degrading roads to dirt-roads. Something I could recommend is the Network Extensions Project I was talking about in this thread earlier. I see Only the bare necessity then. Would you mind if I ask you for some example pictures? :DDDDD
