At least some people are using construction=yes as trolltag (with
intended meaning equivalent to [highway=construction; construction=*]).

In this situation I would decrease road class of partially closed road
- for example from primary to residential in case where it is open to
  keep it usable for local residents but not intended for transit
  traffic. In so long-term cases it would be OK to tag also new
  maxspeed, lane count etc.
