So today I spent quite some time correcting tags of three major roads in Luanda ANG, Kitwe/Ndola ZAM and Windhoek NAM. The three roads were tagged as freeways.
While they may kind of look like freeways, nowhere along the extension of these roads is there proper signage identifying them as such; the T3 dual carriageway from Ndola to Kitwe has many 60km/h limit zones, which automatically takes the right from that road being called a freeway.
The Windhoek B1 Western Bypass has all the structure to be tagged as freeway; however, freeway signs in Southern Africa are blue (K53 code); B1 has all its signage in green. Often authorities refrain from taking that step so that slower traffic is not restricted from using the road under the access restrictions that apply to motorways. This is the case for Windhoek.
The unnumbered road in Luanda is de facto an expressway, and it actually carries the name in Portuguese, which is Via Expressa. Also, the very intricate road configuration in Angola makes it rather difficult to always tag roads correctly, since the passing (inner) lane is also the exit lane to U-turns and other road links, which exist in a great number on most primary roads in Luanda and other cities. Non-observed speed limits range from 30km/h to 90km/h, so this factor alone doesn't allow any of these roads to be tagged as freeways.
To the taggers who were there before me. Please understand that I corrected all your tags (about 200 of them), and this alone would possibly trigger an edit war; I strongly discourage you from doing so. If you have any enquiry about the last edits of mine, please drop a comment on this entry, or PM me.
