This guide is intended as a reference for use during the eld data collection phase of the provincial process in assessing sh passage at culverted sites.1 It is an important part of the provincial assessment process which uses a holistic watershed approach. The eld data can be used as part of the development of a sh passage restoration plan2 or as part of regular road maintenance inspections.
The objective of this technical note is to help road owners and managers assess the suitability of heavy vehicle configurations for resource roads. Basic information is presented about the relationship between truck weights and dimensions and elements of road geometry. The information should be useful when evaluating new truck and trailer combinations for a road system, planning the use of specialized equipment transport vehicles, or considering road upgrades. The intent is to encourage managers to ask the right questions and, perhaps in some cases, draw attention to the need for specific analysis to ensure road safety.
