There are two 9/11 Memorial ceremonies scheduled in Crossville Sunday, the 15th anniversary of the devastating attack on the U.S. The first is scheduled for 8:30am at the County Fire Station on Livingston Road where a section of steel from ground zero is erected which was donated to Cumberland County a few years back.  Another memorial is a dedication of the newly constructed Post 9/11  Combat Memorial at the Veterans Memorial Park on Main Street beginning at 2:30 Sunday afternoon.  This memorial commemorates those Cumberland County residents who have given their lives in post 9/11 combat.
