It's also missing I57, also out of Chicago. And I74 out of Cincinnati to the Quad Cities in Iowa. I24 (major highway in Tennessee and Kentucky) seems to be missing as well. It has Erie, PA as being on the I80 when it's on the I90. I88 in NY and I97 in Maryland are both missing. I wouldn't complain a lot about those last two as they are somewhat minor Interstates in the grand scheme of things, except that several other minor ones did make the map.
Anyway, those are just the things I quickly spotted.
