Thanks! That helps a lot, I can see why it makes sense to not have them as roadways. I was completing work someone else seemed to have started. I might do the next town over, so I may change over the border along Loch Raven to be a separate way. Thanks!

Also added changeset/77880658

I tried first to add a point on the highway and the road underneath it that lined up, but that incorrectly added an intersection. So instead I added a boundary line between two points that were near each other, one on the road, one on the elevated highway. Is there a different way I should do this? There is another spot in Towson, Maryland that has the same problem, so I want to make sure this is a good way to do it. The boundary of Towson has errors that I am trying to fix. I filled in a bunch of missing sections along Loch Raven Boulevard, but there are still two places (this being one) that don't make a completely enclosed section.
