There is a bridge mapped where Davis Road crosses the freeway (just south of here).  That's almost certainly what StreetComplete is asking about.

beddy, the random untagged lines you see all over the central valley are left over from a landuse import by https://www.openstreetmap.org/user/nmixter (I think?).  Since they're untagged and not part of any relations they shouldn't be affecting anything, but should probably be cleaned up.
