The National Trust, along with the Road Ahead Partnership and state and local partners, is seeking a National Historic Trail designation for Route 66 due to the sunset of the Corridor Preservation Program in 2019. National Historic Trails are nationally significant historical travel routes designated by Congress. There are currently 19 National Historic Trails, including the Santa Fe and Lewis and Clark Trails. This permanent designation, which would not increase regulations or restrictions for Route 66, will bring greater public interest and investment to the communities along this iconic highway and encourage their economic revitalization. Most importantly, it will help preserve Route 66 as a vital, iconic, and evolving piece of Americana for generations to come.
