The National Trust for Historic Preservation, a heritage charity, has placed the famed highway on its 2018 list of the 11 most at-risk sites. The Trust highlights architectural and cultural spots it deems in danger from development or neglect.
Route 66 is up for designation as a national historic trail. The Trust says it would bring “recognition and economic development” to historic sites along the famous road. To have the road a national historic trail, and therefore officially protected, the US Senate would have to pass legislation and Trump would have to sign it.
