I remember a few years ago someone telling me that when the 5 was being planned that the routing was going to go along US 99 and through Coachella Valley. But that San Diego was a buig influence on making sure the 5 went to San Diego. I have looked online to see if there is anything to this, but haven't found anything. So I thought I'd ask on here. Is that true?

That wouldn't make sense, since the point of Interstate highways was to connect the major metropolitan areas in as short a distance as possible, right?
If there was ever a plan to send an Interstate through the Coachella Valley (and it appears this was never a proposal), it probably would have made more sense to route either I-10 or I-15 through the area.
