You can't put the rue du Chapelain on a node with the (bidirectional) chaussée de Bruxelles, because (1) that's simply not where it is and (2) it would imply that you can turn left from the rue du Chapelain into the chaussée de Bruxelles - you can't, you have to take almost the whole new roundabout.  I hope I've done the cycling routes right now, but in any case, the rue du Chapelain can't be where you put it.
