Unable to answer "What height limit is indicated here?" – Railway-Road Crossing – node/5105595620 via StreetComplete 59.3:

The "railway" is Pittsburgh Regional Transit's light rail. The roadway is at the same level. The tracks and road diverge on the same plane; the tracks and road are not above nor beneath each other.

Should these paths inside Sandburg terrace (condo development) be marked as private access?
