Lately I've been working on this project, which will include more add-ons in the future, but this is all for now.
The plugin includes a bridge on the ground level (I thought that was unrealistic to go up a ramp to cross a bridge in the middle of a city, most of them are on the same level...) also some statues to decorate the bridge and a channeling of the river with walls, ramps and platforms. For this part i'm missing a road linetool, but I don't know how to do it. (colabs are accepted on this point

So... I hope you enjoy!
