Temporary Haul Roads and On-Bench Haul Roads. Temporary haul roads and on-bench roads should be maintained at a minimum of the 3.5 x the width of the largest vehicle using the road. If the road width is excessive, the time spent grading and watering for dust suppression is non-productive and expensive.
