Photo update as of Tuesday, April 30, 2019. Not sure this has been posted.....the Skyliner tower closest to the Hollywood Studios station has been painted tan, which has a more pleasing appearance than the mottled steel gray towers.

Under the Skyliner towers in the wooded area between the Hollywood Studios parking lot and the Caribbean Beach resort Skyliner station, what appears to be large gravel has been spread out over the "corrugated" black sub-surface. (Pardon the blurred photo, taken from a moving vehicle.)
Thanks for the pics! Very good to see some paint on that tower. Now, how about doing the same on all the rest!
