Hyphens, En Dashes, Em Dashes

Q. Working on an architecture book that uses a lot of duplex addresses—i.e., 1522-1524 Main Street. Thought it should be an en, but someone pointed out the numbers are not inclusive, as 1523 Main Street is not part of the address. Is that correct? Should it just be a hyphen? Thanks!

A. Whoever pointed out that the numbers are not inclusive has a very good point. A hyphen is the better choice than an en dash in that context.
