A road? Were you looking at the floor plan for one of the underground parking levels?

first diagram in the link is traffic flow. there's a blue circle going all the way around the building. appleinsider has kindly cropped out any sort of legend, i suppose it could be underground though.

Ahh, you're right. I took a look at the PDFs and the blue circle indicates emergency access routes.
