The photo of the two San Mateo-Hayward Bridges was taken in the summer of 1967, not '68 as I stated earlier (the vertical lift span on the old bridge is lowered in the picture.)

The "west tower and two remaining truss spans" were removed in the summer of 1968, not 1984 - the 1984 date is when the towers and spans of the old Dumbarton Bride to the south were removed.

I believe the photo entitled "Bridge circa 1967" was actually taken in the spring of 1968 - this image was used as a cover illustration for the San Mateo phone directory that year.

The second image was used on the cover of the 1968 San Mateo telephone directory, if my memory serves me right. The coming of the replacement span in late 1967 to me was a graphic reminder of the rapid changes that were taking place in the Bay Area...
