Crossing signs are used to identify locations where the historic trail route crossed an existing road or highway. They help raise public awareness of the historic location of the trail. Ideally, these signs are used where evidence of the trail is still visible, but they may also be used where the trail is no longer visible. These signs can be used on almost all speeds and classes of roads, although you probably won't want to use them on high speed and interstate highways.
