[OSM-talk-be] intersection looks very wrong -> use PICC with JOSM

[Jakka]

I uploaded the intersection.
Feel free to look.

Route du condroz from the intersection to right. I saw that there are 
lot of turn arrow to go left???? there the highway is split in two 
separated highway . You cannot turn left. Is this correct or should it 
there be merged in one with 5 lanes....or are these old marks perhaps 
separated with curbstones.?
