According to Trafikverket the road ends here, and nothing north of here exists. Instead it seems to branch off to the west into a grid system.

I can't see these on any sattelite imagery, maybe things have changed recently or are currently changing. Updates may be needed.

Björkön is now a municipal nature reserve (kommunalt naturreservat). The border of the nature reserve needs to be added or imported. I'm not familiar with the process of doing this however.

Can't see this building on imagery?

According to Trafikverket Road Network open maps this does not connect to the road towards the east.

This stream is suspect. I can't see it on Bing or Maxar. And it would go right through a house?
