Another suggestion from a reader: Where in Montreal do a street (“rue”) and avenue of the same name intersect?
Bonus half-points if you want to throw in streets and crescents, streets and boulevards, streets and terrasses, etc., which are much more common.
UPDATE: I should have excluded numbered streets and avenues (too easy). The answer I (and contributor Jean Naimard) had in mind was Alexandra St. and Alexandra Ave. in Little Italy. But I’m sure you can come up with others.
