re Jawbones, the "simple" solution which of course won't have occured to the council elves and safeties would be to remove a small section of the fencing that penned you into the jawbones, so that a temporary matting path surface could be laid paralell to the jawbone path, meaning the optimum route across the road was still the crossing.
It would have taken 20 minutes with the buzz saw and could easily have been welded back in place later.
If the jawbones were closed for a few days it would be one thing, but this has been weeks and I assume it might end up being months.
