The Trail of Death signs are part of a larger auto tour route through Johnson County, highlighting the Santa Fe, Oregon and California trails.
The state of Kansas recognized the Potawatomi Trail of Death in 1994, passing a resolution declaring the trail a Regional Historic Trail.
The Johnson County Park and Recreation District provided funding for the signs. Overland Park crews installed and will maintain them.
