Hello all together,
I´m not complaining about optimizing the way via the JOSM optimizer function. In some cases the road is replaced by another road not created by JOSM but some other tool (I do not have in mind and have to check). Bridges and tunnels are deleted and connections to interchanges are cutted. In addition these roads are made only very roughly (as mentioned in my previous blog).

In the other case a part of a highway (let´s call it the the northward bound part) is simply erased (maybe peaople think highway as double lane is enough). But also in that case all IC´s and junctions are cutted.

Dear lyx,
here in Korea I´m sometimes facing the problem that the people doing something strange to map are unable to understand English language so it is hard to ask them why they did and even harder to explain taht they something wrong.
But maybe I´m wrong in transferring the German approach to map a highway always as 2 roads in different direction is not longer applicable (in that case I´m asking myself how a routing SW can work on the OSM dataset).

If there is a chance to restore it would be helpful to know how.

Best regards + thanx a lot for your comments Dieter = vineldi
