How do I set just this small segment to no auto traffic (I think it is general: no) without setting the whole road to no auto traffic. Access on this road blocked by gates, must be a resident with RFID tag to enter. All guests have to enter through the main entrance which is staffed so this entrance segment needs to be set to no auto traffic.

The access on this road blocked by gates, must be a resident with RFID tag to enter. All guests have to enter through the main entrance (on Old Meadow Rd and Provincial Dr) which is staffed and can allow guest in.
