It's not quite Interstate, but it's close?

Interstate comes very close, but the rounded edges are throwing me off because they don't appear to be consistent! Also the E's don't quite match up. I'm hoping this isn't a custom because I'll have under-quoted it, darn the luck. Any help will of course result in much good karma, good vibes and best wishes sent your way...:-)


I'd say that someone added a stroke with mitered corners, converted the outline to a path, then rather clumsily added mitering by hand on some of the inner junctions…
