oh yes it does the map clearly shows richmond and furthermore ""between"" implies richmond, sure its not only richmond, but i-80 is the major artery into san francisco and oakland which are major job centers and people from as far north as sacramento vacaville and fairfield commute through richmond and the rest of thios portion of freeway daily. this is not my point of view at all, in fact it is not a point of view it is a conclusion based on caltrans research reported by the media. I'm not opposed to ""part of"" being worked into the wording that is fine. when editing wikipedia you should improve wording not remove wording that is technically off and well cited as you did. thats borderline vandalism.
