You have a good point here.

Normally, short-time changes for roadworks are not put on the map, because they have a lot of unwanted side-effects (e.g. for researchers using OSM data to measure accessibility of a territory and getting wrong results because of some roads being temporarily unavailable).

The wiki says we shouldn’t care if it’s less than 6 months.  But for main roads or boulevards, it is still worth updating the map even if it’s 2-3 months.

I wouldn’t mind if you would change the map here.  Fill the "note" or "fixme" tag on the ways themselves explaining this is temporary.

The most important point is: do it if you can be sure to survey it again in the future and undo it when the works are finished.  (As long as you don’t create a note saying something like "survey needed" which would put the burden on other mappers, who already have to monitor about 200 open notes asking for extra work. 😫)

Have a nice day.
