Map the Duplicação da CE-085 (see e.g. http://portalpecem.com.br/pg_obras_ce85.asp, http://www.cearaagora.com.br/site/2014/02/ce-085-obras-de-duplicacao-estao-quase-concluidas/)

set max speed

Not sure why way/335600674 is tagged as golf course.. Also other features seem improvable, e.g. way/335600673

Not sure on the mapping here - Western Freeway/Highway end/start should be around osm.org/#map=15/-37.4902/143.7917; the recently completed duplicated parts should probably still be
- marked as trunk
- designated as A8

map dualling

A4 extension mapping seems wrong; it is not a dual carriageway, and rather a motorway link; see e.g. https://www.youtube.com/watch?v=zK0om2K0Sb8&t=98

way/46040701 seems like a private golf course, can someone with local knowledge confirm that?

Golf course closed, remap camp ground, see

and

Please provide details on these two pitch & putt courses (way/115566952, way/115566951), such as name, website, phone.
