AT&T expands Big D campus

​​​DALLAS – AT&T is expanding its downtown campus with the purchase of the Interurban Building, a nine-story former rail station and office that has been converted to apartments and retail.

The building at 1500 Jackson St. adjoins AT&T's office tower complex along Akard Street.

AT&T started construction last year on a $100 million effort to revamp its four-block downtown campus, which it calls the Discovery District.
