barely signed road reference code (near northern exit from Zakopianka tunnel) (approximate location: <a rel="nofollow" class="external free" href="https://www.openstreetmap.org/?mlat=49.64512&amp;mlon=19.91318#map=17/49.64512/19.91318">https://www.openstreetmap.org/?mlat=49.64512&amp;mlon=19.91318#map=17/49.64512/19.91318</a> ). It is some internal code, not used for navigation, not used on reassurance markers and conflicting with road code applying to it (roads 7 and 28 were going though that road section at time of taking the photo).
