That unit went by primary roads, the last movement was downhill so it isn't subject to elevation modifier. Heavy bridges cost 0 points. Conditions do not matter for primary road movement but it is Normal. So a unit with 24 movement points went 6 kilometres in a turn, all of which by road movement on a primary road (4 movement points).
