I think that's actually a screengrab from a really good video on the topic (was probably already posted elsewhere on DDF):
This map made up some new interstate highways with some pretty creative routes. There is no actual I-50 or I-60, due to concern over confusion with the previous U.S. Highway numbering system. https://en.wikipedia.org/wiki/Interstate_Highway_System
LOL
It's all discussed in the video - whoever did the screengrab just pulled the image too soon (in the next few seconds after he discusses 50 and 60).
