Roughly 184 jobs at Lexington's postal processing center on Nandino Boulevard could be in jeopardy as the U.S. Postal Service tries to pull itself back to financial health. Lexington is one of 250 processing centers nationwide, and one of seven in Kentucky that will be studied in the next three to four months to see whether it makes sense to consolidate services, according to an announcement Thursday from the U.S. Postal Service. More than 35,000 jobs across the country could be affected, with savings of $3.5 billion.
