STEAM Workshop link now available, click download then click on (Main File) option.   This interchange has been made to be as realistic as possible based on real life photographs. I've done my very best to make it as symmetric as possible, but keen eyes will find some very small imperfections.   DDIs are safe and efficient interchanges. I'll let wikipedia explain why since I'm no engineer.   From wikipedia:     Includes three versions:    Ground. The interchange is built just like in real life, with only 1 overpass to save money. This one has two lane one way on the diverging part. Ground Highway. Just like above except diverging part is made from three lane highways too for increased capacity and speed. Elevated. Same like the first one, except the whole thing is elevated off the ground and further ramps are made from one way roads.   The assets come with no highway stubs attached to make it as small as possible for ease of plopping. Just attach highways to each end.   Remember you can use right-click to rotate the asset for plopping.       To install, unzip file, then move the files of your choice into \Users\*YOU*\AppData\Local\Colossal Order\Cities_Skylines\Addons\Assets   Replace *YOU* with whatever your user account name is on your machine.   Please note the AppData folder is hidden by default, you'll have to show hidden files in explorer to find it.     Visit my Asset Studio for news on upcoming uploads.   If you like this product, please take a moment to leave a comment or give me a rating, I really appreciate that little gesture in exchange of my work.
