The bug
I've looked in the WB and cannot see a reason why these two AI workers are building a road here. They were building a road in a diagonal (north east) direction and then shifted north west. There's nothing up there at all.
I have a save game and a screenshot.
Trigger
No trigger, just requires observation.
edit: I figured it out, it's creating a very, very long road in order to connect its other cities. I'll leave it to the AI developer as to whether this is actually practical in this particular situation. It's probably not a bug though.
