Most footprints here are valid though some outline gardens visible in imagery barriers like walls can trick you into thinking they're buildings becasue they also cast shadows. Buildings under construction tend to have more going on within the extertior walls. the reason that buildings overlap highways here is because the geomerties are not accurate e.g. the footprint is simply too big to allow the highway to pass. The correct way to address this issue is to make the geomerty accurate so that there is enough space for all of the features you can see. Adding a layer=-1 tag would suggest that the building you mapped is underground. Please keep this feedback in mind when contributing in future. Thank you for your contribution.
