The Nashville Post Office will be closed on Monday in observance of Memorial Day. There will be no mail delivery. Mail will be collected from blue collection boxes located at Post Offices on Monday. Postal officials advise anyone with stamped or metered mail ready for delivery, especially businesses, to drop this mail into a blue collection box at the local Post Office instead of waiting to do so the following day. Street collection boxes will not be collected until Tuesday morning. The Post Office will resume regularly scheduled retail lobby hours and mail delivery on Tuesday, May 26th.
