 For the next six years, Scott worked on getting the road added to the National Register of Historic Places, and finally succeeded when, on September 25, 1997, the National Park Service added the 17.6 miles (28.3 km) within the forest to the National Register. He subsequently wrote a book, Ridge Route: The Road That United California, from the research he had done for the National Register application, that was published in 2002.
