It's an annual event, to remember officers killed in the line of duty.
But this year, the Fraternal Order of Police Lodge Four memorial march comes just days after Lexington Police Officer Bryan Durman was killed by a hit-and-run driver.
So Wednesday's event will have a special honor for him.
The evening began with a FOP meeting, and the march to the Peace Officers Memorial in Downtown Lexington will follow.
The annual march was already planned before the death of Lexington Police Officer Bryan Durman last week.
But FOP members say his death makes this walk even more significant.
They will also be honoring 126 officers from across the nation who died last year.
Normally, the march from the FOP lodge to the memorial includes about 75 members.
This year, it is expected to be bigger because of Durman. A carnation will be placed at the bottom of the memorial in his honor.
The march, which begins around 7 p.m., is only for FOP members.
But the public is encouraged to show their support by lining the streets and watching the ceremony.
During the march, Martin Luther King, Junior Boulevard, along with a portion of Main Street, will be closed to traffic.
