Is this 1 building with 2 numbers ?
Or 2 buildings with 2 numbers ?
Use existing extra nodes to split up the buidling if it's not.

Should the exit/node be moved to this spot ?
By my judgement it should be there. It's not a real issue, but more of a learning-how-I-should-map question, to ensure my future edits are correct.

Kan iemand de naam van deze straat bevestigen ? Komt niet overeen met CRAB.

Are the cycleways still here after the construction work ?

These 2 roundabouts have 2 lanes that limit wich road you can exit to. Should we add this information ? (Signs on the rounadbout are however verry well indicated.) Also how should such a thing be done ?

There is a parking area here for O.C. Boerenpoort.
