Chicago's Old Main Post Office to be redeveloped

CHICAGO (WLS) -- Chicago's Old Main Post Office, which has been vacant since the mid-1990s, will undergo a $500 million renovation.

British developer Bill Davies bought the building at 433 West VanBuren in 2009. He's partnering with Chicago-based Sterling Bay to redevelop the three-million square-foot building into a retail and residential space.

The Eisenhower Expressway runs through the 9-floor building, which was built in 1921, as it turns into Congress Parkway. The old post office was in use until 1997.

The building, which is listed on the National Register of Historic Places in 2001, has been popular for movies shot in Chicago, including "Batman Begins", "The Dark Knight" and "Transformers."
