This zone is probably the most densely-filled with roads. If you open up the map, look for a structure marking just east from the “eye” icon. This structure is a tall building, that is only reachable by a long bridge from the eastern side. The final outdoor skyshard is on its southern side, next to some metal pipe, close to one of the bridge pillars.
You’ll find the rest of the skyshards (numbers 11 through 18) indoors, in public and solo dungeons. The first ten were easy in terms of not fighting anyone to grab them, while the last eight are easy in terms of their locations being marked on the map as dungeons.
Just bellow the bridge.
