The Mountain Fire closure order was amended last November. Looking at the map there appears to be a much less arduous detour than in previous years. I'm sure some hikers have already walked this route:

At approx mile 168.6 take the Spitler Peak Trail south for 6 miles to Apple Canyon Road.
Make a right/go north on Apple Canyon Road for 0.4 miles.
Make a left/go west on Bonita Vista Road for 3.4 miles.
Make a right/go northwest on Forest Service Road 5S21 for 3.7 miles.

Total detour length 13.5 miles.

Here is what 5S21 looks like:
