Is the last change (#38296743, highway=primary --> highway=motorway) really correct? In other maps, this stretch is part of the EN111.
We cycled here some time ago (Rua Arnaldo Sobral, then this segement, then to the south over the bridge Edgar Cardoso) and there was no motorway sign on our way.
The only motorway sign we saw was applicable for way 190236197, going from here to the east, but not for 173916350 or 173916773
