You may add the traffic sign as a node if you want.

It looks like routing is correct here: a motor vehicle coming from Terre Neuve only has one option, i.e. turn left, because on the right there is only a cycleway.  Unless I am mistaken I don’t see what is the problem, exactly.

(That being said, if there is a D1e sign here it will be removed soon because the street is expected to be reversed and go from South to North; that will normally happen in September once "Foire du Midi" is over.)
