By the 1980s, the operations had outgrown even the expanded facilities at the Terminal Annex. The facility's volume had grown by the mid-1980s to 14 million pieces of mail per day, and the annex was plagued by inadequate space, overcrowding and inadequate work areas. Accordingly, the Postal Service Board of Governors in 1984 approved the construction of a new $151 million general post office in South Los Angeles. Almost 50 years after Terminal Annex became the city's main mail-processing facility, the new processing facility in South Central opened in 1989.
