Hi, thanks for your reaction!

If I understand correctly you are indicating the road markings would prohibit a connection from this road onward to the Rua da Lapa segment connecting Rua da Gloria. 

I have driven on this road frequently in the previous 2 weeks and the connection is used to cross the parallel Av Augusto Servero. This is the suggested path offered by another Google owned routeplanner, taxi's and other regular cars drive this route often. I cannot speak for it not being allowed by the road markings -- the ESRI imagery would suggest so, just from experience people do drive this way and it does  appear to be allowed.

However I cannot really find what the stance is at OSM on mapping how roads are used IRL vs what the road markings would suggest so I'll rescind my comments :)
