I see, did you put the notes marker on the exact spot, because if you mean the crossing about here: 56°57'06.6"N 24°23'21.6"E or you mean through LIDAR the many little divots in the earth. Looking with satellite, I can't seem to see roads, so they might be military trenches, they might be still a glitch in the LIDAR map. I have no idea what they are, but NE the divots continue in a straight line so that might be a road, and I don't think that they are military trenches because around here: 57.07057504571693, 24.086275131870227 with LIDAR you can clearly see that they are trenches being zigzagy and deep.
