ABSTRACT ESTHETIC degradation and erosion constitute the major environmental impacts of forest roads. Re-cent observations from an experimental road in Mon-tana show that impacts are strongly related to road cross-section width: cut slope, road surface and fill slope, and the attendant clearing. To reduce impacts, a single-lane road was constructed to carry all traffic, including log hauling. Hauling was simulated for three other road standards and compared with the experi-mental road. In this instance, where 6,787 m3 (1.5-million board feet) of timber was harvested, the single-lane road was probably the best choice.
