Hi. Traffic signs are not consistent here. I based at comments from this note
https://www.openstreetmap.org/note/3034089

I verified in the field.  the answer is: it's complicated.
 The only sign between ul.  Pliszczyńska and the viewing platform in Łysakowo is "C-16a / 13a - horizontal - End of pedestrian and cyclist traffic" which stands in front of the buildings with No. 17 (coming from Lublin).
 There are no other signs (also on the other side), car barriers, etc. The road is normally used by agricultural vehicles (I passed a tractor).
 I don't know how to mark it, I stopped at improving the surface.

If you believe individual signs should be mapped, I'll take a look at that and try to do it, however I rarely use this scheme.
