Forest roads must be maintained in a condition that allows them to handle traffic loads at any given time, which is only achievable if their dimensions remain within the prescribed limits. The dimensions of the elements of the plan, profile, and cross-section of forest roads depend on factors such as soil type in a constructive context, the category of the forest road, and the type of vehicles that will use these roads. In this study, a forest road constructed on soil types IV, V, and VI was examined, and its dimensions were determined. The share of soil type in constructive sense is 63% of V category, 34% of IV category and 3% of IV category. The average width of the roadway is 6.11 m, with an upgrade of approximately 3% and a downgrade of 6.5%. The cross slope of the roadway is 3.1%, while the slope of the cut areas is 120% (1.2:1), and the slope of the fill areas is 86% (0.86:1). It was concluded that the forest road is in a condition capable of accommodating traffic load. However, attention should be given to the wider roadway width and the lower slopes of the cut and fill areas, as these may require adjustments to ensure efficiency and safety.
