Up on the ramp you're coming from the tollway that is, you can see quite a lot from up there. But on the street view the Google car is heading SW at grade on the 2-lane frontage road, the main freeway lanes are to the right and become elevated, and the overhead ramp had to fly over everything that was already there. Notice how the frontage roads give a street address and access to properties facing the "limited access" highway.
