Was looking over some photos of some random stack interchanges and was wondering what is deemed the tallest stack interchange in the US?
People in Dallas gloat about their "High 5" Interchange (I-635 and US-75) and I read that that one is 120 feet tall.
Any place with a taller "stack" interchange?

The Judge Harry Pregerson Interchange in L.A. (junction I-105 and I-110) beats the "High 5" by...five feet.
I wonder what the basis for measurement is. Dallas' claim for the High Five seems to be based on the elevation difference in profile grade lines for the US 75 mainlanes (533 ft at lowest) and the west-to-north ramp (652 ft at highest).
