The purpose of the Purple Heart Trail is to create a symbolic and honorary system of roads, highways, bridges, and other monuments that give tribute to the men and women who have been awarded the Purple Heart medal.
The Purple Heart Trail accomplishes this honorary goal by creating a visual reminder to those who use the road system that others have paid a high price for their freedom to travel and live in a free society. Signs placed at various locations annotate those roads and highways where legislation has been passed to designate parts of the national road system as The Purple Heart Trail. The actual format and design of the signs varies from state to state. There are currently designated sections in 45 states as well as Guam
