Aah! OK, that's understandable and easy. You don't have to manipulate the old "farmland track" to Zülpich Industriegebiet. The reason lies in the street from Nemmenich. Someone who mapped this before us did connect both ends at separate joints on L162. This is not "usual". I did it the "right way" and joined themn together in the middle. This should resolve your routing (could take a few days).
Kind regards, bye! :)

Hello Spixi,
I strongly suspect you created this note: note/4439582 Please stay logged in when creating a note respectively don't forget it if you edit yourself after that anyway. I closed the note so we discuss here. I honestly don't know what was wrong before. I think now it is even more wrong. You created two separate ways at the crossing, but in real life I cannot see a divider between the two lanes. So one lane like before was correct.

oops, my comment was mistakenly pasted here. It belongs here: note/3650065

That's wrong. There is a speed limit sign of 70 before the junction to Heimerzheim to reduce speed at the crossing area. And there is no annulment sign to 100 because of rural area after that, in fact there is just another 70 sign. After that, there are another 70 signs (even 2 on both sides). And then there is a speed camera at the bridge of A61. I mapped everything and reworked mistakes in the whole area. So you were definitely completely wrong.

Hello "Hubert Hallig", someone created a note that a way through the forest at Wachtberg-Pech that you mapped basically does not exist. Please have a look: note/3416139 and answer it

Talpmas, please respond!

Hi, you already added the restaurant while the OSM situation still shows a construction site. There is an open note, can you close it by revising the area? That would be nice note/2562568

We need feedback, please answer here first before continuing mapping. I also wrote a PM.

Hi, are you on vacation ;)
Have you had time to look at this way?

Hello themartinix,
another mapper opened a note about this way which you mapped. Please feel free to join the discussion and solve the question why this is a service way or track: note/3230624

Hello, Talpmas? We would like to solve the question

ford=stepping_stones is wrong here because there is no water: way/1053137871 | way/1053137870 | way/1053137868. Furthermore, please only map restrictions that are signposted on the ground. horse=no is useless. Of course no horses should ride there. Please only map traffic sign restrictions. If there is no traffic sign, remove all restrictions.

same thing with the parking spaces like in changeset/119921330

amenity=parking is only for the parking lot as a whole. The individual spaces must be mapped with amenity=parking_space. Can you please correct that? amenity=parking_space
