How long will the maintenance work last?

Construction sites under three months are not mapped in OSM!

The reason is here:

"The reason why we don't map short-term closures is simply that many OSM-based navigation apps only update their data every three to four months. If you map a closure today and take it out again in two weeks, it will be correct in the online data, but - assuming they update in the meantime - it will still be in the satnavs until August, then users will be routed via unnecessary detours and then complain that OSM is no good ..."
