COLUMBUS (AP) — The struggling U.S. Postal Service is expected to announce plans to close about 250 mail processing centers around the country, including 10 in Ohio.

The $3 billion in cuts to be announced today would slow first-class mail service, ending next-day deliveries of stamped letters.

A list released earlier this year of processing centers targeted for closure included facilities in Akron, Athens, Canton, Chillicothe, Cincinnati, Dayton, Ironton, Steubenville, Toledo and Youngstown. A union leader said processing offices in Cleveland and Columbus would be the only ones left in Ohio.

The consolidation of mail processing centers is in addition to the planned shutdown of about 3,700 local post offices. In all, roughly 100,000 postal employees could be cut as a result of the various closures.
