If you didn’t know, the 16th fairway was connected to the 3rd and went around the left of the PN and another 100 yards down that side, from the time The Old Course was widened from a reversible nine, until 15-20 years ago when the R & A changed mowing lines to toughen it. I never dreamed it would be changed when I wrote my book, so I didn’t think it needed a diagram.
Fair enough, I still think that centerline bunker work best when it forces interacting with other element on the course, which, in the case of Corner of the Dyke and Woking 4 (as Ira noted) is the out-of-bounds. TFE wrote about
Kapalua Plantation Course 5 last year as well. I guess my main idea is that, right or wrong, there is a class of player that will see a bunker placed in an otherwise safe landing zone as frustrating. On the one hand, they can just get over themselves, but on the otherhand, I think obfuscating a centerline bunker is probably a good way to keep the fair police satisfied.
I would propose that there are lots of ways to achieve what a centerline bunker does without actually using a bunker (if the goal is to force interacting with some other element). A short wall crossing the fairway at an angle could create the same split fairway, a shrub, an existing structure, even a large hillock. Lots of things could make players pick a side or end up with an obstructed shot, but for some reason the choice is always a bunker. And bunkers, I suppose, seem a bit more manufactured than other options whenever they are in a non-links environment, and add significant cost as well.
However, if the point is to just increase the randomness of outcome (which I think is fun), then pepper those bunkers effectively at random and call it a day.
