Which street refers to the title equivalent to the English "Princess of Wales"?

The street that corresponds to the title equivalent to the English "Princess of Wales" is Dauphine Street. The term "Dauphine" refers to the title historically held by the heir apparent to the French throne, akin to how "Princess of Wales" is used for the heir to the British throne. In this context, Dauphine Street in New Orleans reflects the deep historical ties and influence of French culture and titles within the city.

The other streets listed do not carry a similar royal connotation. Burgundy Street, for instance, is named after a region in France but does not have a direct connection to a royal title. Chef Menteur Highway and Deslondes Street also lack a link to the concept of royalty or its heir, reinforcing that Dauphine Street is the most fitting choice given its association with the historical framework of nobility and leadership in France.
