This was TRACK not PATH, it's a track used by construction machinery. Yes, old path is gone, but this is completely different way. And it still exists, here is 2 days old photo of the situation on the ground: https://www.r00t.cz/i/k05snkkr.jpg
It's perfectly normal to map tracks that go trough construction area and I will be adding it back, it goes all the way to Letnanska, just before recycling center. 
And yes, I actually live here and map by surveying what's on the ground, not by ortophoto alone.
