Yup no worries.... With my rig I'm over 52ft. Also there are many many semi trucks tha drive that road every day ( mostly night) a great road no issues.
There is a long hill ( down hill) on the Princeton end coming down towards the mine.
Use lowest gear put on your 4 way flashers on and use your breaks to keep your speed in check, and you will have no issues.
