Have a look at Mariahilferstrasse in Vienna. There were the same arguments. Where does the traffic go? Which streets are gong to be made worse in compensation for making one better.
The answer to that was, none. No street was made worse to accomodate more cars. The traffic in the case of Mariahilferstrasse simply mostly disappeared. It did not spill over to other streets.
