just saw this on AZ offroading:
"Hewitt Station Rd. is closed to thru traffic. Posted as of March 2017. Local residents complained of noise and dust and the county who still maintains the road put in a gate. I have a picture of the alt routes to take to circle around. I can email it if you like. It was quite a surprise as we didn’t stage anywhere near posted signs and found this out on our decent and return. We instead had to take the 60 at milepost 223 for 8 miles to return to our truck/trailer.
I have the AZ backroads book and gps – neither off which foretold this"
I was just there the day after christmas. If you come in off the road Queen Valley road it is open for a few miles. Look up the “Montano Loop Trail” on AllTrails and it will give you specifics of where the trail starts.
