You are correct that the toll plazas for DHS parking are being built as shown on your map. I was referring to the center of the map I posted, where it shows the road dividing, and then two Stop lines. I see that as a guard booth controlling access to the SW resort. I shouldn't have called it a toll plaza. It is closer up the road than where the current toll plaza is.
Those stop lines will be painted on the ground for traffic control. I presume there will also be Stop Signs there. Here below in the red arrow is the access to the Resort driveway. Circled in red is the gatehouse, also in red.
Here is a close up with just the blueprint. Red arrows point to the gates.
