One thing I'm not sure about with in this image is that this concept retains two parallel roadways around the perimeter, backstage. It seems only one service road is necessary. The other, outside road under the power lines is a legacy of routing guest traffic around the back of DCA to the Simba lot, right? Seems it can be replaced with show buildings, etc., they're already storing stuff long there, etc. and new parking garage coming.
Maybe these changes apply (not including a bridge to Simba, just not enough info)?

What the overall area looks like now:

EDIT: For reference, SWGE shows how close a show buildings can be to the property line and public roads, and how narrow of a service road is necessary.
