Having been to Petrozavodsk I can say that there is very little good quality road lighting outside the city centre, as can be seen in some of the photographs here the timber roadside poles appear to only be a 3-phase power transmission line, which may be the airport supply. Given that it was not dark, but foggy at the time, I too initially wondered whether they had mistaken a road alignment for the parallel runway, but can't see a candidate for this.
