was not complete in San Josť until about 1978. It was numbered
as Route 21 in areas until the freeway was under construction.
maps even had this section signed as "17" and 17 (now 880)
The interchange was not complete with US101 until about 1982. I
lot of photos of I680 North on 4/12/2008. I added even more on
2/19/2009, and that was on a really good day!
