First of all the taxi way bridges that are elevated, I see ground spiking out... Also I see this in Dallas actually, when I cross the bridges my airplane jumps.
Also I was editing your AFCAD a bit, and as I was placing parking stands for the long term parking used by Qantas at the mid north section of the airport, I noticed that there wasn't any taxi-way incursion to that part of the airport... Here are some shots:

The rest is just créme dés la créme
Love the In 'n out burger!
