In the beginning, Paradox launched Cities Skylines without trams and tram avenues. You can read all about the introduction of the game here. Then Paradox came up with the Mass Transit update, but with no real tram avenue possibility. Almost every city in the world where the trams run in the streets. They have street avenues where the trams run in the middle. So! It was really nice to see that Streetlamp user on Steam Workshop, managed to release some very beautiful street avenues with trams.

Not only Tram avenues, but also Tram stops are included
But that’s not all! He even managed to build quite a nice Tram stops too. You can, in fact, choose to have platforms on both sides in the middle of the street or only on one side. Fantastic!
You can either download the 4-Lane Road with Tram Platforms package alone or you can browse to Streetlamp’s page on Steam Workshop where you can see more of his avenue streets with trams tracks in them. Distrita has also tested this MOD and it works perfectly. Why didn’t Paradox add such tram avenues with the Mass Transit update? This should be standard! Great job for sure!
Including Streetlamp users, there is also a user calling himself BadPeanut. He has even created smaller streets with tram tracks in the middle. These tracks are green and so the cars can’t drive on the green field. However, he has also made Bus Lane in the middle variants too. Adding this to your city transforms your city a lot for sure to become today’s age streets with public transportation running on them. Distrita has tried to mix these streets without issues with the latest update of Cities Skylines.

Six-Lane roads with Trams on them is another great Tram MOD update
It is nice with avenue street tram tracks! But, how about American type of six-lane roads? Ifriqiya user on Steam Workshop has made quite nice addons to the six-lane roads for the game, where this person has added tram tracks. It looks really nice. Also, he has made red bus lanes where the trams tracks are too. Quite nice I think!
So, now you can add two quite nice MODs. Distrita has tested both of them and they work nicely. They simply add that little extra to your cities in Cities Skylines game, which is great. The developers of this game never thought it would become this popular, but amazing MOD adders like these people adding such parts to the game keeps the game alive for way longer.

All of these street addons with trams and bus lanes, also have variations with trees and without trees. Use the streets that fit your city best. Creation is really the only limit in Cities Skylines.. And do share them on Facebook. Trams for life!
