I am realizing the question of whether the road is submerged or not is irrelevant. Because the road isn't submerged. At least not the part of the road you removed. This can be seen if you use the recommended image layer for Norway, called "Norway Orthophoto". This image layer is dated to 2019, but by having a look at sentinel images from 2022 I can confirm that the road is still not submerged.

I suggest you revert this change and rather update the lake boundaries instead if you want to fix this issue.

You should never ever default to using Maxar Premium Imagery, Bing aerial imagery or Esri World Imagery when editing in Norway. Always, and I mean always, check first whether you can use "Norway Orthophoto" first. This layer will have significantly less offset than the layers you mention, and will usually be more up to date and higher res.

I totally get that this was an honest mistake, but the point above is incredibly important. If you do use the sources you mention you risk decreasing the quality of the data in Norway.

If you have other edits in Norway relying on Maxar, it would probably be a good idea to re-visit them using the imagery source I mention.
