This will be right for most cases, but not always. Sometimes access
through the gate may be restricted, but free on both sides of the gate.

An example: a service area at a highway. For regular traffic it is
available only from the highway, but there are gates (normally closed)
to local/service ways outside. Only authorized may open and pass the gates,
though the roads on neither side is officially closed for traffic.
