I have only played the course 10,000 times, well maybe played 5000 and walked/ran the property 5000 times.
I am not exactly sure what level that posted picture is taken from. I think it could in fact be the far left of the back teeing area.
Behind this area is the teeing area (higher on the ridge) for the fourth hole going out. Frankly, the closer one gets to the green, with a shorter shot (and closer to the gorge with less elevation) the more ominous the shot becomes.
Gil and George rebuilt the teeing area ~110 yards and at this angle with a back flagstick, you are unable to see any green-space beyond the flag. It is flush up against the Palisades. This also becomes a problem with long uphill putts to a back pin position as the putt looks like it will roll forever if long.
I probably should not admit this considering the skill level of golfers on this site
but I have been long and had almost 100 yards shot coming back because of the steepness of the area beyind.

the picture of the bridge GB posted is taken from the 16 green, 3 teeing area. The third hole is the branch of the bridge to the right. Straight ahead gets you to 16 tee and the rest of the property. It is possible to pass others but because of the routing the major part of the span is only used in one direction. Our grounds crew does a great job of maintenance here (there is a longer and higher span near #12) but it is a hoot to watch people on them for the first time.
