I am actually translating in most instances as "strip" - or actually geschlagene Schneise as cleared strip. Only for the first reference, in the principal part of the text, near the beginning, which is also the first quote above, I use "(fairway lanes)" - lane because its the technical term, fairway to be better understood. My idea is to communicate to the reader what this actually was - a strip cleared in the forest, often 20 or 50 km at a stretch, that the Roman soldiers could march up and down. And probably some 20 m wide, to reduce the exposure to attack from the sides. "
