union/downtown

english-test.net/toeic/liste … lding.html

please explain:

  1. It’s at Fourth and Union.
  2. Where is the Stafford building? It’s downtown, near the library. - shouldn’t it be:
    It’s in/at the downtown, near the library.

Thanks…

It is at the junction of Fourth Street and Union Street. (Fourth and Union are the names of the streets.)

It’s downtown is correct because the preposition ‘down’ is already included. Another one is not needed. ‘Downtown’ and ‘uptown’ are treated in this way.

It’s downtown / it’s uptown
but
it’s on the west side of town / it’s on the north side of town, it’s in the southwest corer of town, etc.

Thanks!
You meant: corner of town?

Yes, sorry.
