The sections where construction hasn't started are definitely not
"construction". And if we start distinguishing planned from proposed,
they should certainly be "planned".

For what it's worth, a highway=planned way inside a
landuse=construction area makes sense too. Unless you plan to update
the data regularly and/or depending on the timeframe, there's no big
need to have a highway=construction step between highway=planned and
highway=final_value.
