Note regarding the above map:  it was photographed on the wall at the Yolo bypass maintenance office area, but we have not seen that map otherwise in any other records.  The date of the map came from a white label added-no date showed on the map.  Therefore this may not be an authentic map but a planner's rendering from the 21st century.
