Where was this Guam photo taken? (Solved!)

I took this photo in either 1974 or 1975. When I first posted it, I couldn't recall exactly where this photo was taken. Thanks to the help of a wonderful reader, I now know where. This is the GITC building,  at 590 S Marine Corps Drive in Tamuning. The view is to the north toward Tumon at the intersection of Chalan San Antonio or GH 14.  I took the elevator to a top floor to get this shot. It had to be one of the tallest office buildings on Guam.

Much of what's pictured here is gone. The area to the upper left of this intersection is construction equipment and some stacks of supplies. Can't make out the name on the building next to it.
