Roads made real.

CSUR is the largest road mod ever for Cities: Skylines.
It helps players to more efficiently build realistic road infrastructures and massive road networks.

CSUR provides you with the richest road content for Cities: Skylines in an unprecedented scale.
More than 400 different CSUR road assets are available on the Steam Workshop, and are packaged into 11 asset packs to suit your city-building need.
If you cannot find your desired CSUR road in our Workshop collections, you can even create your own CSUR road using our generation software, as simple as downloading Blender and running one command line.

Visit our discussion forum to connect with CSUR players around the world.


Help us improve CSUR.

CSUR is a set of open-source software under the GPL-3.0 license. It takes in road modeling elements and/or textures (licensed separately) and generates everything needed for a Cities: Skylines roadtypes asset. CSUR welcomes code contributions to help make it better.
