How to add construction with conditional access?

So, basically there's no way to map such restrictions? there's another case as well, where the crossing is restricted only for cars until 31.10.2021 6pm-6am: https://www.tsk-praha.cz/wps/portal/root/o-spolecnosti/mapa-staveb?poi=606454ffd8d9a78a0e9cee3d.

It is possible to map such cases with conditional restrictions. The point is that we do not want to map such short term restrictions which lie within regular update circles of data consumers like routing apps.

1. It's not "no way" to OSM. The cause is applications using OSM data usually don't update their data very frequently (even if they are not reviewed and directly used), so better keep these limited-time changes separate to avoid unintended problems. You would want to ask for the software you are using to support temporary:*=.
2. This one you can add motor_vehicle:conditional=no @ (18:00-06:00), but you must remember to change it back. (Which is another factor not favoring maintenance of shorter period data)
3. Although https://wiki.openstreetmap.org/wiki/Conditional_restrictions#Use_with_keys has a motor_vehicle:conditional=no @ (2018 May 22-2018 Oct 7) example, this is argued against in https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/temporary_(conditional)#Why_not_:conditional? .
