little traffic, rolling hills through the woods, very smooth compacted gravel (very roadbikeable but watch out with the descents)
this road runs right next to the Russian border (at a distance of only ~100 m of it for almost 2 km), not that you can really see any of it from the road, but do keep in mind that the border zone that starts right at the side of the road (marked with signs and yellow “Rajavyöhyke” tape in the trees) is only accessible with special permission (so if you need to take a nature call there or something, pull over to the other side of the road instead)
