Cities Skylines Detroit Outlines Outline SVG is a single design from the Cities Skylines Extra 23 Skylines bundle, available on its own. The download contains this design in AI, PNG and SVG. The vector formats scale to any size without losing quality, so the same file works for a sticker or a wall print. Every design on uVectors is included with your plan. Download this one on its own, or take the full bundle if you want the rest of the set.
