Each day officers put their lives on the line, and each year Indiana State Police honor the sacrifice of those who have died with a memorial service.
The tradition continues Wednesday morning at the ISP post with a special dedication ceremony.
The service begins with a traditional roll call of ISP units killed in the line of duty, after each name called, troopers fire off a single shot.
This year three highway bridges in Southwestern Indiana are being named after local officers.
That includes two I-69 bridges over the Patoka River at the Gibson/Pike county line.
One will be named after Trooper William J. Trees and the other after Oakland City Officer Michael Deno.
Both officers were killed in Gibson County.
The I-64 Big Bayou River Bridge will be named after Sergeant John Hatfull who was killed in Posey County.
