To accurately describe the terrain characteristics of the Ardennes Region, the simplest analogy might be a scaled-down version of China's southwestern area, which is notably lacking in flat terrain.
Under pre-war consortium management, compared to the population of the Ardennes, the area's road network was quite developed, with even rural highways in very good condition. However, there was one issue — the roads were predominantly two-way single lanes, wide enough only to accommodate two side-by-side 4-ton trucks. Though all roads were originally designed to support heavy 70-ton tanks, the width of the roads undoubtedly limited the traffic flow. A quick influx of large forces would inevitably cause traffic congestion.
